Hey Terry
There may be 7 part numbers available, but the difference is in the year of the car, Heated Seats (or not), and DSA (Stability Control). Volvo only showed one part number for this particular one, which is 0142699G04.

If you want to swing by, we can try swapping it out to see if that's the problem. Worst-case scenario is we get a chance to *properly* diagnose it while the module is out of the dash.

See if you can find out what codes popped up when they scanned the module, too. Scanning requires a dealer-only break-out box (no connection to the OBD-2 port) so I have no way of doing that here.


Original car was an '02 S40 without heated seats or DSA.

Short list of symptoms:
1) A/C module would power up and compressor would come on for about 1/4 second at Key-On, then both would shut off.
2) One or two of the backlights in the module (behind the knobs) would work properly, but never all three.
3) Entire HVAC system would work properly *sometimes*. When it came on, it would stay on....but usually it didn't come on at all.

I'm not sure exactly where the connection was. It was repaired at Volvo, and I didn't get the car back here until after dark, so I didn't see it myself. It took them almost a week to figure out that it was "somewhere" in the relay box.

As a side note, I don't see how ANY business can stay afloat if they're charging $1200 for a non-refundable repair that they don't even know will work. Good thing (for them) they're the only Volvo dealer within 50 miles......
