I've never had air in the truck since I've had it. But since I'm getting older ~ I can't take the heat...so I took to a couple of shops to find out how to get it to work. Mind you I brought this truck from Credit Acceptance. It seems like as soon as I paid it off all of it went to crap. The motor went ~ they claim timing chain but any way...I brought a new condenser and the polls, freon etc. And now the back works and the front blows heat. They are telling they are going to have to rip out the whole dash board to get to fix it and when I let them do that...they STILL DON'T KNOW WHAT IT IS...so can you imagine cool air in the back and heat in the front and it's summer time..not to mention NOW the window get stuck in the up position when it's too hot!!!! You've got to be kidding me...it's a money pit!!!!
