 Heater/ac functions intermittently then fails completely. well know problem where placement of ribbon cable to potentiometer breaks loose, partially (intermittent failure), then completely (total failure). quoted cost at any dealership $900-$1,000. i did repair myself in one hour for a cost of $10. quick search on the web uncovered many many of same incident and, fortunately, detailed repair instructions.

 Heater runs erratically--blowing fine and then switching to cold air and then if i jiggle the control can get heat again. had the dealer repair in fall of 2009 (about $95), but it has started acting up again.

 2005 toyota highlander. eratic temperature control from heater. when set on cool will sudddenly blow hot air and vice versa. on-line complaints indicate this is a common problem resulting from defective control unit in this and other toyota vehicles over several years. the control know comes loose and then the wiring behind it breaks from the circuit board resulting in eratic air temperatures. i also have concern that this electrical failure could cause other electrical shorts or problems. dealer recommends replacement of entire control unit at prices ranging from $500 to $1500. on-line consumers report fix only requires resoldering the 3-wire contacts at a cost of a few dollars. it is obvious toyota knows about this issue and the relatively easy fix documented with pictures on-line but continues to deny that it is their problem. it is a manufacturing defect that should have been dealt with several years ago, but charging owners huge fees for replacing a simple component seems to be what toyota feels is the appropriate solution.

 I wish to report a safety defect on my 2005 toyota highlander. when traveling at speeds above about 35 mph i cannot hear the turn signal clicker. i am 69 years old, but do not have any significant hearing loss. not being able to hear the clicker sometimes causes me to leave the turn signal on when it should be off. although i have not had any accidents due to this problem, it could cause other drivers to make hazardous decisions. for example, if i had my right turn signal on by mistake someone waiting to make a right turn onto the roadway could be thinking i was about to make a right turn off the road. i've contacted toyota about changing to a louder flasher, but they do not have one. they were not able to help me at all. yes, the turn signal indicator lights work on the dash, but they are not in my field of view when i'm looking at the road and looking at them is an unnecessary distraction. i think audible turn signal indicators should be on all cars and the sound level should be adequate for all drivers who can hear. preferably the sound level would be manually adjustable or automatically adjustable according to the car speed. *tr

 Toyota highlander 2005 4cyl. the heater control will only blow extremely hot air that makes the vents almost to hot to even touch. no events led up to this problem, though in researching online forums, other toyota highlander owners are having the same defect. i took it to my local toyota dealer and the service associate acknowledged this is a problem with this vehicle. the cost to repair is $899.00. this is excessive for a heater on a vehicle a little over three years old and a little over 30,000 miles. it appears this is a defective design and the wires are not welded properly. the center nut below the heater control knob loosens over time and the wires then break free from the contacts. *tr

 Toyota highlander, 2005 yr, defective ribbon electrical cable between heat/air control on dash and computer in car. heat on, hit a bump in the road and air conditioning comes on full blast or the reverse in the summer. other reports on internet indicate same problem with 2001 & 2002 year vehicles. comments are the electrical cable become hard and brittle with age and breaks or cross connects causing problem. dealer cost is $600 - $900 to correct -- replace whole unit -- although one comment is that new wire can be soldered. it is my opinion that consumers should not have to bear the cost of a manufacturer's defective part. *tr

 Tl*the contact owns a 2005 toyota highlander. while driving approximately 60 mph, the low tire pressure warning light illuminated on the instrument panel. the indicator remained illuminated until the mechanism was turned off. the failure occurred whenever the vehicle was driven on the highway. the contact pulled over to the side of the road and observed that the tire pressure was not low in any of the four tires. the vehicle was taken to an authorized dealer for diagnostic testing, but they could not determine the cause of the failure. the failure occurred on six separate occasions. recently, the vehicle was taken to an authorized dealer and they stated that the failure was related to the computerized system. the estimated repair cost would be $2,414.60. the vehicle has not been repaired. the failure mileage was 21,000 and current mileage was 23,000. updated 10/16/08.*lj updated 10/17/08.*jb

 Tl*- the contact owns a 2005 toyota highlander. the contact stated that the door locks on the vehicle did not lock when the vehicle is placed into gear. the only way that the doors lock was by manually locking them or pushing the power lock button. once the doors were locked they could not be opened by the pull of the door handle only by the power lock switch or manually. the contact was told by the dealer that it was only a programming issue and that they would program it for him, but he later found out that the vehicle did not have a door lock program feature. *ak updated 2/22/2007 - *nm
