2007 Ram 6.7 blows hot at idle, but very cold while moving. I've had everything replaced. The high pressure cutout cycles the compressors at idle every few seconds. I've noticed the fan doesn't pull enough air thru the condensor unless I cover the opening at the top of the radiator. Anyone have experience with this problem?

Mine does the same. My brother is supposed to flush the system and refill it and it should work. But I cant say cause he aint done it yet!

Mine does the exact opposite. Cold at idle, and hot while moving.

I just had to re-charge mine last night because it would cool but wouldnt get COLD at ilde or moving. I have heard stories about the fan not pulling enough air at idle to let heat escape - not sure if that is true or not
