So its now 102 degrees here in boise area and i have no air blowing in the front of my 99 suburban, but the back blows like normal just hot air not cold so im assuming it needs to be recharged or add some 134 to it. I thought it was a blower motor and replaced it and still no air. So next thing i found online is ac clutch, and it is not spinning when i turn the ac on so i checked the volts and it had around 14-14.5. What should i check next or should i get a new clutch? Any advice would be greatly apreciated
