Hello Everybody,
I have a 2018 GMC sierra denali 6.2L, and a few weeks now, the heating and A/C is not working.
When I put it into manual blowing, and not automatic, I hear the blower start and shortly after stops.
Does anybody know what the cause is of this problem?
The garage here, have connected the car to the computer, but no errors or whatsoever.
Sorry for my bad english, i am from belgium!
