I don't have ac in my trucks. One has the parts but they are not operational. I live without AC in the trucks fine. They both have rear sliding windows. If you don't have a rear slider I would definitely get one. When I open my back window, door windows, wing windows and kick panel vents its like a wind tunnel in my truck. Almost impossible to be hot while moving.
Yeah I'm gonna head to the pull a part sometime soon and get a sliding rear window. I've heard they're pretty cheap for our trucks and anythings better than this. The windows have been working alright but it really sucks sitting in traffic at 5 oclock! lol I really shouldn't complain though. Its my own stupid fault.
