I know the air conditioning is pooched, I had the air conditioning and
recirc lights flashing, I did the calibration, it would cycle from hot to
cold and then all the different vents (but not different speeds not sure
if it should). After the top rear window wiper button would flash and it
would stay on cold even when it was on hot (van was sufficently warmed up)
If I hit the button the air cond. and recirc button would start flashing
again and back to hot air. I only have highest fan setting working which
is what I am trying to fix. Any suggestions??
The van has to be warmed up in order to pass the calibration test. The
purpose of the test is to see if it goes from hot to cold, if the engine is
not hot it will never see hot and fail.
The reason why you only have one speed is because it is in the default mode,
the heater resistor has burnt out and when this occurs it only allows high
speed, replace it, located just under the glove box mounted into the heater
box. then do the calibration test. Note if the A/c does not work don't
expect this test to pass. why would you disconnect the a/c if it already
