Have you run the self-diagnostic? Are both fans running in the engine compartment? Is the clutching engaging?Hey guys,
Today the A/C on my 2003 MDX stopped working. The temp here is around 90 degrees and humid.
When I turn the A/C on and manually turn the fan speed on high, only warm air blows out.
Then, if i press the full auto button, it goes into recirculation mode and the fan speed starts to drop immediately to a very slow speed blowing warm air. Temp was set at 60 degrees.
The fan speed would also slow down when I raised the temp from 60 degrees to say 66 or 68 degrees. The outside ambient temperature was 78 degrees.
I tried installing a jumper wire on the blue thermo fuse, but no cool air. My cabin filter was relatively dirty, so I removed it from the air box and will replace it with new one.
I also used an ohmmeter on the blue wired fuse and it showed a closed circuit.
Not sure what to do next. Don't know if it's worth ordering new thermal cutoffs from digi-key since the jumper wire did not work and the ohmmeter showed the circuit was intact.
Your help would be greatly appreciated. Thanks!
