I replaced the controller and now I am back to the original problem of the compressor not engaging.
The very first original problem was the ac stopped blowing cold at idle.
The compressor low side is WAY HIGH in the readings.
The compressor is not locked up and will turn by hand.
Last Saturday just going down the road the compressor stopped engaging.
Blowing hot.
I’m back to my original issue and the symptoms except now Compressor not engaging with low pressure terribly high.

I’ve read that the condenser can cause the issue of not cooling at idle. I was wondering about that.
I just hate taking out the condenser if this is not the problem.
Thanks to all for the help.
