Not blowing Cold air while driving slow or stopped at the signal
Hi, my suv not blowing Cold air while
driving slow or stopped at the signal
but it's blowing cold air while driving
more than 40mph
I BELIEVE there is a TSB for this. Required a software upgrade, which is like $100 to do at the dealer. Check that out, it IS a known issue that can be solved.
Is it possible in Kuwait or online ? Thanks for answering.
What is TSB?
Technical Service Bulletin. In Kuwait, I don't know. Can't do it online, gotta have a service shop that has the ability to upgrade GM's software.
I found one of the TSB's, there are more if I recall. Bulletin No.: 06-06-02-003 One other thing..... IF your engine is running hot, or you're losing coolant, the computer will shut the A/C off with a thermal switch. So when you get up to a certain speed, the fan will cool it down and AC will start working again. I've had that problem myself. But, I still need to update software in mine to fix it permanently.
