Sun sensor is in and working but still no A/C, they are still trying to figure it out.

when you say no a/c is the compressor not cylcing at all or is it jusnt not blowing cold? are you testing it at max cold setting with recirculation on?

Compressor does not come on at all.

Well it the relay that turns on the compressor that is not working. Pep Boys jumped the relay and the A/C runs but the problem is that relay is part of a almost $700 control box that isn't going to be here until Wednesday!

Ouch!

Yep $1k to change the radiator is now $2k plus!

Yea they charged me 1014.00$ to install my CSF radiator. The radiator itself only cost 600$

I sure would rather that money be going to coil overs but it is what it is.

Fine was just under $1k.

At least pep boy figure that out GL.

They need to trace back the trigger circuit to see if you have a wiring issue. (Broken wire in the harness). I have fixed a many an issue due to this when I worked at Nissan as a tech. I have a hard time believing the control box is part of the issue without everything being tested. Jumping the control relay proves nothing. They are missing something.

I agree it doesn't sound right but say everything is working. The computer is saying turn the compressor on but you can't see the signal at the compressor. They tested the wire between the compressor and the relay and it's fine.

They need to test from the trigger wire. Relay to computer (ECM). That is what energizes the relay to pull the contacts down.

I have seen a burnt connector in the main harness cause a no start issue on the brake neutral safety switch circuit.

Thank for the info, I will make sure that was tested.

actually i think the ac auto amp behind the heater controls triggers the compressor through the ipdm, it manages the pressures and things and sends the idle signal to the ecu. it's hella convoluted. you could actually swap the relay in the ipdm but you need another ipdm to harvest the relay from so hang on to old one incase another relay ever fails.
