2002 TOYOTA HIGHLANDER User Comment / Complaint

The problem is with the air conditioning a/c control unit. i'd talked to several toyota owners about this, and they said that they have had this problem , and each has taken it to a dealership near them and got the same reply. this was a very expensive replacement part. the dealership that i went to said they have seen a few vehicles. the owners i talked to owned highlanders,4 runners, and minivans. my wife's highlander is a 200, 2 the other vehicles range from 2002 to 2004, for as i know there hasn't been anything reported about this. i sent an email to toyota and all i got back was they haven't had any recalls for that. the problem with my wife's highlander was that the heat stopped working during the winter. the only way to get it to work was to keep turning the knob until it would start blowing warm air, but it would not do it for long. the a/c worked fine ,but when winter returned, there was no heat. if the was a continuing problem, and more dealers found out about, why weren't they doing something about it. if one could research this i would appreciate it.
