CX-9 Dies when AC is turned on...Any ideas?

[fiddleman]

Hey guys got my ac working it’s cold but got another issue when I come to a stop or slow down like turning it dies every time. What could cause this..?

Which year CX9?

Cars have a mechanism to give additional gas when idling with the added load of the AC running in order to maintain a constant idle speed. Find yours. It might be due for cleaning or fixing or replacing.

In addition, have you tested your battery voltage?

Well now my compressor want come on and I don’t know why according to the everything that I have read the AC relay is supposed to have B+ voltage on pin 30 and it don’t it has it on 87 and when I tried to bypass the relay and jump those two relay won’t even click in and this is a new AC compressor

Yes 12.27

Ok. And make sure it's 14v when the engine is running. When that's not the case I have had cars stumble and die on me when coming to a stop.
