A/C high pressure goes to 450 psi at stop signs and shuts off compressor until pressure bleeds down to 340 psi. It works okay while rolling.

 

My apologies and thanks to m-chan68 in another thread. I'm just an amateur on A/C systems and this is my first A/C unit with electric blowers. I didn't realize the high pressure could go so high if there was no cooling. The cooling fans weren't working and I found a burned contact in the fan connector that plugs onto the fan control module. The fans worked with 12VDC applied directly to the connector and the control module had 12 VDC on the output pin but the two wouldn't make contact when plugged together. Now do I have to buy a complete new fan assembly or can I get a replacement connector somewhere? Any help is appreciated.
