Lexus climate control

The climate control on my 97 es300 goes wacko intermittently. The buttons are unresponsive for 5- 10 minutes and then they work again and then go out. then nothing wrong for 6 months, and then it happens again. Any Ideas??? I have not had a mechanic look at it yet.

That going to cost you, most likely you have to dis-assemble the control module to check for burnt. Loose connections.

Try for another module. That’s what my son’s needed. Over $400 from the dealer, $200 used and working.
