Hello my name is ***** ***** thank you for your question.

The AC relay is built into the IPDM. it's not a relay that you can remove since it's internal. If your AC is not operating and you were thinking of manually jumping the relay to make the compressor come on to charge the system, that won't work. You need a AC machine to charge the AC system properly. Most of the time and when I say most of the time, I mean 90% of the time when the AC doesn't work, it's due to freon level. The AC pressure sensor is what tells the Ecm to turn it on based on the pressures in the AC system.

Do you ave any more questions on this?

The system is totally charge. The a/c does not turn on.

How do you know it has the proper amount of freon?
