Intermittent Air Conditioning Problem - 98GS400
The air conditioning on my 98 GS400 works about 90% of the time, but ocassionally when I turn it on it doesn't work at all. No fan...nothing. When I switch it off and then on again it works...although I have to sometimes do the on and off thing a few times in a row before it will work.
When it is working, again 90% of the time, it works great.
Any ideas what could be causing my intermittent problem?

I will check next time I am having the problem. The auto button lights up and functions when the air conditioning is working. I don't know if I have tried auto in the past during one of the times it wasn't working.

Defective switch/relay ,wiring harness issue to blower motor,dead spot on blower motor resulting in it not kicking on. If you have access to borrow someones a/c control unit test it out best way to see if you need to replace the control panel. Make sure no rats have made a nest in your a/c system and chewed some of the wiresto the blower motor. I see that all the time and they chew all kinds of things in the car other then that. Good luck!...
