a.c doesn't work when truck is idle on 2002 Dodge Ram 1500

My air conditioning works fine when I am driving. When I stop at a light or I am parked the air being blown in the cabin becomes warm. I've tried reving the engine to see if that would help but it does not. even if I am just rolling down a hill the air gets colder. If someone knows what this is I would also be interested in how much it might cost. Thank You in advance.

This sounds like a fan issue. When your truck is moving, air is moving through the radiator/condenser, but not when the truck is stopped. At a stop, the radiator fan performs this job, so that is where I would start.

I had the same issue. It is the fan.

If you push a paper clip in the back of the fan and push the rear plate in alittle bit and keep it there it will work. It is still working in my truck.
