So I have a 07 Duramax. I've replaced the AC compressor, dryer, high side pressure switch, condenser, and ac controls. I turn on ac and it blows cold. after a few minutes the ac snow flake shuts off. Then will com back on. If I'm driving it wont shut off. Also when im driving and get on my truck it will come out of max air.

I choose heavy duty for more engine rpm percentage and they do last longer because they have a larger heat dissipation...Helps prevent failures

Do you have an aftermarket tranny cooler up front blocking air flow? That could potentially require you to get a larger duty clutch fan to get more air flow at idle and low speeds.

As far as ac goes. Except the low pressure switch. Everything is brand new
Well change it too then. Lol...Check the circuit with a meter. Or better yet see what the low side pressure is when it kicks out when manifold gauges are connected. It might be doing its job.....
