 We have battling the problem of the sunroof leaking on our hummer. there is drain tubes in the corners of the sunroof this water is supposed to go do these tubes then on the ground. how ever this is not the case. in most cases the water leaks down the pillars in the trucks dash compartment and soaks the carpet on both sides and the head liner. we have had it to the dealership on several accessions and they just say they were stop up but they just leak the next day like nothing has even been done. they charge 300 dollars to do this. i have the technician tell me that nothing he has done will fix this off the record..whe the water is pouring in there is nothing you can do the onstar goes off and your lights on the inside go dim we have had the cpu short out due to water the blower controller both front speakers and behind the dash all the metal parts are covered in rust. when the electrical parts shorted out the wires were burnt and we were driving when this happened on one occasion and had to have it towed. we have tried everything taken it the dealership did not help. the truck is allways damp inside. then of course the smell of the carpets. i even have contacted gm and just said take to the dealership and they are gona charge the same thing. i am scared for my wife and family to drive this truck. we will not even leave in the garage due the risk of fire. if you google this problem there is over 60k topics on this and forum after forum about it. and every is saying this. it is obvious that this is a design flaw and gm is not going to stand behind this. i think something should done about this before something very bad happens to someone in these trucks. i just want it fixed nothing else.

 This will be the third blower motor resistor that i have had to replace. this time i am replacing the harness because it burned up so badly on two terminals. gm has yet to acknowledge this problem... i paid $26 for the resistor, and it's going to be $30 for the harness, and i save a ton on the labor because i am a mechanic, but this is a potential fire hazard. there is an air flow in this area, and can fan or start flames in this area if it occurs while driving. very dangerous! this is my second report. *tr

 As i was leaving work the other day, my hummer h3 lost its a/c. as i checked it out i found that the a/c pump would turn on, but there was nothing blowing thru the vents. as i did an internet search i found a blog regarding this very problem, it seems to be an issue with a resistor and connector in the blower system. it melts and becomes useless. this is not only an inconvenience at 100 plus degrees, it is a fire hazard as well. i believe this needs to be looked into. *tr

 Very very common problem with gm products and excessive problem with h3 heaters. you smell something burning in your vehicle then your heater fan starts fluctuating and ultimately stops. there are reports that the dealership will fix the burnt plug, but it won't fix the problem, it'll burn up again. now i have no heater in january in ohio this should be a recall !!!!!!!!!

 The blower on my 2006 hummer h3 stopped working while driving down the highway and we smelled a burnt plastic smell when the blower stopped. the smell eventually went away, but the blower never worked again. i found that this is a huge issue for not just hummer owners, but other gm vehicle owners. the resistor and plastic clip were melted together and when disconnected, fire damage was evident. this resistor for the ac blower is located right under the glove compartment and luckily nothing flammible was close to this when is blew while driving down the highway. i also have pictures of the damage and subsequent danger this issue poses. othere posts of people seeing this issue. http://www.hummerforums.com/forum/hummer-h3-17/air-conditioning-problem-grrr-16020/page2/#post264883

 On october 30th i smelled a faint scent of something burning inside my vehicle, but could not find anything. november 1st was our first cold morning so i started my car, and had no heat. the system wasn't blowing, but the heater a/c controls were lit up. since i am a mechanic, and have knowledge i went right to the fuse box in the engine compartment. the fuses were ok. i then went to the blower resistor pack which is located under the glove box. the orange power wire in the harness was burnt up pretty good, and the terminal molded into the harness pack was also burned up pretty good. i then went online to google this problem to see how common it was, and was surprised to see how many complaints there are about this problem, not just regarding the hummer line, but within gm vehicles itself. i called the service tech where i have my work done, and he was very familar with this failure.

 As i was driving to my office from a lunch break, my a/c and ventilation stopped working, i turned the on and off dial and air never came back on, shortly after that a strong burned smell came from the glove box of my vehicle, i pulled over and noticed a little bit of smoke coming from underneath the glove box. i did some research on the interned and discovered it was a burned out vent blower resistor (ac delco part# 15-80647) i have since replaced it but it still not working. i have the burned part if ever needed, i must say i don't feel at all safe with a situation like this as it has never happened to me. i decided to include my complaint as i have seen many people with the same problems on this vehicle, a fire is eminent and should be prevented.

 Overheated and melted resistor and wiring harness for the hvac blower motor on a 2006 hummer h3. this has happened to my vehicle and a friend of mine. also many owners on the internet have had this same problem. it is so prevelent that many parts suppliers are advertising the parts for sale

 Purchased 2006 h3 with 58k on it. at 61k the a/c blower would increase in speed for no reason then go back to its setting. at 62k it stopped blowing for no reason. online search of h3 a/c blower issues gave me a place to start looking. fuse was ok, checked resistor pack (pn 11221007.011) under dash and found pin a melted with sign of recent electrical fire due to shorting out. the orange connector on the harness was also melted. further online research of this issue revealed that it is a common occurence. i called dealer and was told they have never heard of it. i purchased resistor pack, connector, and pins then changed the componet myself. works good so far....

 I bought my hummer h3 in august of 2009, used at a chevy dealership that is a sister store of chevy/hummer dealership. my 2006 hummer was fine until the cold weather hit. the first incident occurred around the first week of november. i was leaving to go to a friends house around 9:00pm i went outside however to turn my heat and my heated seat on, and about five minuets later i went out to my car to leave and my car was freezing with no fan motor on at all. after staring at my fuse box and reading the crappy owners manual for around and hour, we came to the conclusion that no fuses had been blown. the next day i drove my vehicle to the chevy garage. the service man checked it out and said that he would take care of it. a week later i was driving back to pick up my hummer up. on the way home from the dealership i got about five miles up the road and my car was filling up with smoke. i then returned my car to the dealer. a week later again i picked my car up, drove fine and get this i even had heat for about a month. until it was around christmas and the same thing happened, dropped my car off and a week later picked it up. two weeks later and it was around the middle of january, the same thing happened. i took the car to the garage yet again and the fixed the same thing that they have been fixing, no change and no investigation on the problem. the fifth time happened around five or six days after i picked my car up from the previous time getting fixed, only this time they brought it to their sister store the one with the hummer certified technicians. i finally got my car back two weeks later. then around the last of the cold weather it happened again it was the beginning of april. i got it back and had no problems, not even with my a/c, which i run all summer long. now this november was the first time it happened again since last april, and it

 I have two 2006 h3 hummers both with the 5 speed manual transmission. upon acceleration from a stopped position in first gear, depressing the clutch for the shift into 2nd gear the engine rpms revs to about 4000 and stays there. shifting into 2nd gear & releasing the clutch the rpms drop back down. accelerating to about 3000-3500 rpms, depressing the clutch, again the rpms climb to around 4000 and stays there. the same thing occurs during up shifts ... this has happened no less than 7 times on one h3 and 5 times on the other h3. the hummer dealer can find no stored codes, and can not duplicate this. gm has been notified, but nothing has been done to repair this problem because the dealer can not supply defect codes. this has been going on since august '06 with no end in sight. i have asked the ecu be either reflashed or replaced and was told it was too costly to just put parts in without any codes. i believe the software could be corrupted. and is not aware anything is wrong. thus there are no codes. *jb

 Last week i was driving locally home when my h3 cab filled with smoke blocking my vision and the a/c blower stopped...i nearly drove into a tree...if i had been on the highway at speed, i would be dead. i took the car to a local shop, as close as i could get...anyway my dealer was shut down as gm went into bankruptcy. the mechanic found that a wiring harness connector burned out, creating the smoke and cutting the blower off (see photos). i reported this to gm, asking them for refund of costs and to investigate this serious safety matter. they refused because i am out of warranty! i believe they are covering up a serious manufacturing flaw...when the mechanic phoned gm for the wiring harness section involved, they had it in stock ready to go...evidently, gm knows of this flaw. if this problem is not taken seriously, someone will be killed by it! *tr updated 08/20/09.*jb
