I need to know the exact location of the A/C Relay on my 1994 Volvo 940. If it is behind the fuse panel then which relay is it among the several there? Thank you.

I will do that when I get home. Thank you for the prompt reply. Hopefully I will find it as we are pretty sure it is the problem.

Well, we replace the compressor, accumulator and orifice tube and the pressure switch tests fine. Something though is intermittently causing the A/C to not engage and when the mechanic was testing the pressure switch and had a light tester on he had me disengage the A/C on the panel and then engage and the A/C did not come back on. He concluded there has to be a relay of some kind between the ACC and the pressure switch causing the issues.
