Winter’s over, and I’m having A/C issues. Before I go any further, many thanks to DanG144 for the detailed fan and A/C troubleshooting guides I found while trying to diagnose my A/C.
I have a 2002 Jetta ALH with manual A/C. Here’s what I’ve found so far:
What might I be missing? From the details provided, have I come to a reasonable conclusion? I don’t have a “duty cycle” meter, so I can’t test the pressure sensor G65 as detailed in the troubleshooting guides referenced above. I've seen the J293 fan control module on Ebay for about $45, but that price seems incredibly low even compared to other online retailers. Too good to be true?
Thanks for taking the time to read this…
I have a 2002 Jetta ALH with manual A/C. Here’s what I’ve found so far:
- 344mm radiator fan had failed, so I replaced it with a new one. Both fans now work on low and high speed by jumping the pins in the radiator cooling fan thermo switch.
- The fans do not work on low speed when the ignition, AC and interior fan switches are switched on. All the fuses on top of the battery and in the interior fuse block are fine. However, when I REMOVE fuse #S16 from the interior fuse block, the fans run on low speed with the ignition on. Is this normal?
- All the tests for power and grounding on the 4 and 14 pin connectors to the fan control module J293 from DanG144’s troubleshooting guide appear OK.
- I do have 9.5 volts at the connector at the compressor with the engine running and AC switch and interior fan on, however the compressor clutch doesn’t engage. If I provide battery power directly to the compressor with the engine off, I can hear a “click” from the coil.
- Yes, the dash switch illuminates and the interior fan works fine.
