Re: Chevy Traverse 2009 - Testing why the low heat?
Followed the video's instructions:
Got out the OBDII reader and measured the kpa/psi given off by the ac high pressure switch while the AC was off, it was 420/60.
From there I turned on the AC and it constantly oscillated from 712/102 to 420/60. Not sure what is the normal for this car but I'll proceed to replace the ac high pressure switch since it's the easier cheaper option.
Also because the main concern continues to be the fan which is constantly on upon starting the car, thus preventing proper operating temperature & heat to the cabin; I doubt it's a bad (stuck open) thermostat but that would be my next item to look at.
What you all say?
