1994 Volvo 940 Ac Unit Getting Electricity Works Fine Manually Bypass Circuit

Whats the ac pressure read when the car is off?If the pressure is too high or low the ac compressor will be shut off.

OK
So the pressure is very high when it is not working
However when I "jump" the AC it works and pressure is good
So I still think it is electric

How high is the pressure with the ac off?

In the red zone
How is this direction of thinking going to help ?
I am trying to tell you that the wire going to the AC has no juice
It would have to have electricity to shut off !!!
When I do get current to it it works and does NOT shut off and pressure is good
It is Not the AC , it is electrical.
Can you help or not ?

I can help do you have turbo or non turbo so I can findthe correct wire diagram?

Turbo
Thank you
Gabe

Alright with the ac on and the car running you should have power across the low pressure switch both wires on the accumulator?You should also have power across the high pressure switch both wires behind the center of front bumper?

If you're talking about the cable which is on tope left (sa facing car) right next to where the refill nipple is:
that's where there is no electric no matter what

Where your drier is?thats the low side switch that gets power from your ac controls switch.Go back to your ac controls switch see if you have power out of the green wire with a red stripe with the ac on and the car running?

Thanks
Will check tomorrow

Alright keep me posted.
