I need some help!
My Suburban has developed an AC issue. It has the dual Climate Control system and every once in a while on the drivers side it will go from full AC to full Heat. The only way to get the AC functioning again is to turn the ignition off and restart. Passenger side works fine.
What should I look for to correct this issue?

Welcome to the forum.

Someone here might be able to help. Might try disconnecting the battery for 10-20 minutes.

 

Thanks Shark!
I pulled the neg. cable today while I was cleaning my air cleaner. We'll see if that does the trick.
Why would this possibly fix this issue?

 

Welcome to the forum, disconnecting the battery can reset some of the control modules hopefully get them working correctly... basically a reboot...

 

It's the Chevy equivalent of Control, Alt, Delete.

 

Thanks for the welcome and the help in2pro and 73shark! I like reading the topics here and the help will be put to good use. Hopefully my truck will continue to purr and I won't need much repair help....lol
Well, since I did the control-alt-delete the ac has not acted up, cross the fingers and hope for the best.
Thanks again fro the help!
