climate controls aren't working
My 2001 GS300 has been rock solid, except I recently lost almost all functionality of the interior climate controls. Specifically,
1. When I turn on the fan, it only blows out cold air - not air conditioned air, but cold air. When I adjust the heat setting up, nothing happens.
2. The fans are stuck blowing air out to the windshield (defrost). When I attempt to use buttons to redirect air to my feet or vents, nothing happens. (This is a change from what was previously the case. When I first experienced a problem with this, the air would only blow out of the vents. I disconnected the battery and reset the car and now it only blows air out to the windshield).
I brought the car to my local Lexus dealership to ask them to run a computer diagnostic test to figure out what the problem was. They ran a test and said that there was a problem with the computer that controlled the fans/heating/cooling system, but they couldn't be sure whether it was a chip or a board or what else, and told me that it would cost more money to even arrive at a full diagnosis of the problem than the car was worth...
So, I am stuck. It's cold and getting colder and I have no heat and have freezing cold air in defrost mode.
Any help or suggestions would be greatly appreciated!!!
