I need help finding this to connect guage. Hot air, compressor turning, high side at 150-152. Compressor kicks on and off with a/c button on dash.. Service ac popped up but codes have been cleared and nothing current or history now.
Please help it's going to be a long day tomorrow...

I think it is near the accumulator or between the accumulator and the firewall. Somewhere in that vicinity.

FSM was virtually no help - apparently they didn't have room for a "Service Port Location" section. Near as I can tell the lines run along the passenger side wheelhouse to the firewall. The service ports may be near the right strut tower in the one pic I could find that was vaguely relevant.

It's the smaller of the two ports that are about 6 inches apart in the line along the fender. I guess there's an orifice tube between them for regulating.. Right from EWILL3RD at the dealer.. Thank you!
