Hi, I have a 1998 Bravada. The climate control resets itself at (seemingly) random intervals. I haven't seen this listed as a common problem, but thought I would check in case it is and I have missed it or if anyone has any ideas on what to check.

Basically, I turn the car on and set it how I want, everything is fine. After a while, it will totally shut off (like it loses power), the blower totally stops, etc. Then it will come back on (with A/C light on).

It gets really annoying always pressing the A/C button to turn it off - does it normally come on by default when you start the vehicle? Oh yes, and I do not have it set to "auto", this happens when I manually set it where I want...

Thanks in advance!

I haven't found anything in the '97 manual on Climate Control yet, I'll keep looking.

Sorry, I can't find any info on Climate Control in my manual.

After you set it on automatic and do not touch anything does it work good?

If there is a problem with it a good engine /body/HAVC capable scanner will show codes and point you you the problem.

Also I would check power feed and grounds.
And make sure R-134A and operating pressure is not low.

Good Luck and let us know how it goes.
