I have a 1998 Dodge Caravan. It was fine till I went to turn the heat on. There was no heat at all.
I ran the calibration test and got a code where the Rear Wiper LED flashed once, the intermittent LED flashed 4, 5 or 6 times. Of course the Rear Wiper LED flashes once before the other codes, 1-4, 1-5, 1-6
It seemed to me the code was saying there was a problem with the Evaporator probe (open or shorted).
I replaced the probe twice. Re-ran the calibration test again and got the same results.
I ran the cool down test and it failed. When it failed both the Rear Wiper and Intermittent LED's flashed at the same time.
Prior to all this everything worked, I live in Southern Florida, so don't need the heat often. I just randomly tried it. It used to work. Now none of it works. I need the AC!
The fan works fine, I can hear the blend doors moving during the calibration.
Is there a way to bypass the "codes" and get back to where I was before all this happened?
