 Well i have problems with my speedometer for a time ot worked and then stopped and so on but now since august it has stopped working together and i'm afraid of driving because i don't know how fast i am going

 The speedometer on my silverado does not show the proper mph figure. it varies from 0 mph to 40 mph no matter at what speed i am traveling. this is especially dangerous when traveling the mass pike as i have no idea how fast i am going. around city driving it usually stays at zero with an occasional spurt to 60. i cannot find a recall from chevrolet regarding this type of problem but there should be. this is a manufacturing problem.

 I own a 2004 chevy silverado 1500 4x4. the speedometer started malfunctioning around 90000 miles. it would work but not read correctly. it got worse and worse. now very very rarley does it work properly. most of the time it reads incorrectly sometimes it doesnt move at all. sometimes it is all the way at max and sometimes it stays on 0 and sometimes it is stuck somewhere in between. the truck now has about 135000 miles on it and everything i find says it will cost between 300 and 500 dollars to get it fixed. i have researched and found that it is probably because of faulty instrument clusters that gm knows about and wont recall. i dont think it is right that i have to pay for their faulty parts. it is very unsafe not being able to know how fast you are going.

 Speedometer begins acting erratically. ranges from 20 -120mph regardless of actual speed.
05/14/199975000
 As i pulled out of a parking lot i hit the gas a little harder than usual as to not get hit and my speedometer went to 180 mph and made the sound of gears spinning but not catching. it occurs everyday since it is a piece of crap and my oil and fuel gauges are gone as well. no repair, the recall is for up to 70,000 miles and since gm didnt notify me i went over before i found out. if it is against the law to speed then i dont see why it is legal for an auto manufacturer to sell a product that in effect condones and forces me to break the law.

 The driver's side ac randomly starts blowing hot air while we are driving along in our 2004 silverado which started about 2 years ago at about 80k miles. in order to get the ac back, we have to pull over and turnoff the engine and then start it back up. some days it never does it, sometimes several times and usually on the freeway but sometimes on city streets too. this is in addition to the speedometer, and other instrument panel issues that have had to be repaired over the last 2-3 years (after the warranty expired)

 The blower motor resistor in numerous general motors vehicles has been known to short out and potentially cause fires. this has been made more visible by a recall in canada by transport canada (transport canada recall # 2011074). i have had to replace the blower motor resistor in my vehicle and the replacement is already starting to malfunction. if this is recalled in canada it should be recalled in the u.s.

 I own a 2004 chevy silverado and i'm having issues with the dash cluster odometer reading correctly. i feel it a safety issue when you can not tell how fast you are going while driving. if your caught going 20 mph above the speed limit, it's concidered dangerous enrecliment. am i wrong? the odometer reads incorrectly every time i drive my truck.

 Problem 1.the plug that controls the blower motor in my 2004 chevrolet silverado melted and started smoking. i replaced it and 3 monthslater it is now happening again. without the use of the blower motor i can not use the heat,ac or window defogger. this truck has less than 50,000 miles on it. when i search online i see that many others have the same problem. their plugs have melted and in some cases have also started fires. not having a window defogger is very dangerous. problem 2. the heater blend door actuator has stopped working. what this did before the plug melted was to control the temp of the air coming out of the vents. when it stops working like it did to me was to blow burning hot air right in my face even with the ac on. imagine driving at 55 mph and have these things happen to you. please make general motors recall their products and fix them so this problem will not occur again. thank you.

 2004 chevrolet silverado 1500 5.3 motor z71 package. dual climate control goes to full heat, dealer said this is a common problem. fixed once under warranty. found blogs online to trouble shoot exact problem and fix myself. some people reported fires. even when ac off it still blows hot air. turning the vehicle off and then restarting it has been working. i do alot of higway driving and cant always pull off and restart the motor. being that heat still blows when this happens and wont stop, putting the windows down does nothing to aid this problem.

 February 20, 2010 i smelled a burning electrical smell. after a quick look under the dash on the passenger side i found smoldering wires from the wiring harness that is attached to the heater fan. the wires run from the heater fan motor to the resistor. the resistor is also damaged. the wires had to be replaced as well as the resistor. the parts dealer said that this part frequently must be replaced on this model truck and they keep at least 30 in stock just for this reason. this vehicle only has 63,575 miles on it. as a result, i was unable to use my heater or defroster which resulted in being very cold on my drive home from work at 6am and i could not defrost my windshield to see properly. *tr

 I have a 2004 chevy silverado 1500 ss, the driver's power seats, driver and passenger heated seats, and mirror dimmer's lose all power. they were working 30% of the time. i took it into the the dealership, they said the wire harness melted and would cost $500.00 to fix, they can't determine why it melted. they left the harness unplugged because it left in, it would cause further damage to the airbags. my drives side aribag will not inflate if needed until replaired. i called gm - chevrolet to make a complaint saying this is a safet issue and nothing due to human error. they said it is out of warranty and is not a safety issue or a defect, they are also not sure of why it melted, it could be many reasons: something touched it, wear and tear, a gm part gone bad. they claim this is not a gm issue. they said because of all this and the age of the car, they will not compensate for any of it, but then said regardless of the age of the car, the wire is not supposed to melt. *tr

 Speedometer does not work correctly. the speedometer floats as you are driving and also shows mph when at a complete stop. sometimes the speedometer sticks at 120 mph. this is happening every time the vehicle is driven. this is a major safety issue since the driver does not know how the correct speed that is being driven. *tr

 '04 chevrolet k1500 - throttle body sensor the issue is that the truck keeps coming in and out of reduced power mode which when it is in this mode it is very hard to maintain speed which in turn is inherently dangerous. in '07 i had the connections cleaned and repaired (under warranty), on july 7th of '08 i had the whole throttle body sensor replaced (out of warranty), and it started acting up again on june 25th of this year. i qualified for the 12 month repair warranty, but had driven over 12,000 miles. out of the blue my truck goes into reduced power mode. i pull over and basically restart the truck a few times and apparently the computer resets and exits the mode. this worked for the first week but now it has to sit overnight. the check engine light will stay on for a day or so, but then will clear. i have taken it to three dealerships for diagnostics and no one can put their finger on the specific problem. the most current one has told me he could replace the throttle body sensor, but can't guarantee that will fix it. he has three more '04 chevys coming in and out of the shop with the same problem. what they have been able to tell me is shown below, but still haven't been able to fix it. scan revealed 2 p2135- throttle position sensors 1-2 correlation. using your site i have found the following service bulletin: 060604026 (nhtsa item number : 10020835). i don't mind spending the money for the repair, i just need to know what i need fixed. i'm worried about pulling onto the highway and then loosing power and causing a wreck. *tr

 All gauges on my 2004 chevy silverado 1500 have failed. former class action suit was filed and won on behalf of truck owners. suit only covers vehicles under 80k miles. mine failed at about 100k. discussed issue with gm and they will not fix the issue. found on nhtsa web site others are having the same issue at about the same mileage. the cluster is a defective part installed in production and seems to be destined to fail. part failure causes vehicle to fail emissions and thus makes vehicle unregistered. part cost more that $500 to repair. no recall has been established at this time. *tr

 I noticed, beginning in august, that the speedometer in my 2004 chevy silverado 1500 began sticking when my speed decreased. beginning in september the gauge began sticking when accelerating, and on october 24th, the gauge stuck at 45mph, even while to truck was in park not moving. i received a paper back in august about a class action lawsuit regarding this mal-function and i believe i will take that, along with some of the research i have gathered from this and other websites, to my chevy dealer and see what they have to say about it. this is a safety hazard and gm needs to issue a recall and protect it's customers. *tr

 The speedometer on my 2004 chevy silverado has stopped working properly. when at a full stop, it reads 20 mph, and increases accordingly from there, so the proper speed is never displayed. it is a constant problem, and consequently the driver of the vehicle is never sure what the actual speed of the vehicle is. the parts have not been replaced at this time. *tr

 I purchased a 2004 z-71 silverado on december 31, 2007 with 16,020 miles. in july of 2008 my gauge cluster started working intermittently, at first only the oil and fuel gauges stopped now my whole cluster has been rendered useless. the dealership is making excuses not to stand behind their product, even though it is a known issue that is common knowledge to almost everyone who owns a gm truck. they have told me that it is my ignition not the gauge cluster, even though everything else that is powered off ignition power works perfectly fine. being a former mechanic i can tell when someone is informed about what they are telling me, these service consultant

 The digital instrument display on my 2004 chevy silverado z71w/53k miles quit working. after 5 minutes, the display appeared. the next day, the digital display did not appear for 45 minutes. all analog displays (mph, oil, water, battery) were ok. the proposed class action lawsuit against gm appears related to the analog gauges only. loss of digital display is also a concern, since transmission gear and any power train, brake, or vehicle warning messages are not visible. my concern is whether the loss of analog / digital display are related, such as a common electrical connector. *tr

 Was driving down the road in my 2004 chevrolet silverado and the speedometer quit working. granted, the vehicle just hit over 100,000 miles, but would not expect this to happen. the needle sits below 0 mph and will occasionally jump to between 5- 10 mph no matter the speed of the vehicle. i am apparently no the only individual that has this issue on the same model vehicle. *tr

 The speedometer on my 2004 silverado k1500 is pegged right now and is not working at all. this happened shortly after the warranty expired. i have seen many similar complaints online at www.topix.net/forum/autos/chevrolet-tahoe/t2bgkbgi55eknu77c. this is unsafe and apparently fairly common with gm vehicles, yet there has been no recall issued as of yet. *jb
