A/C not working

Asked by Whsinsparta Sep 12, 2017 at 12:42 PM about the 2012 GMC Terrain SLT1

Question type: Maintenance & Repair

My ambient air temp was reading incorrectly so I
replaced it with a new sensor when now I have no
temp display and my A/C is not working. I tried to
reinstall old sensor but still do not get temp display
and a/c still does not work (blowing hot air)

Do you need to sync the new sensor with the car's computer first? Check if it needs to be done. It should be a simple task and your service written should be able to tell you how to do it yourself. If not, search u-tube.
