Our 1996 Caravan has developed a strange electrical problem. Recently, when the car was started, the yellow "ABS" light on the upper dash stayed illuminated, and the radio did not work.
A few days later we had the problem again, and we were able to do a bit more testing. What does not work includes:
ABS warning light Radio Ventilator fan Windshield wipers
Maybe more -- we don't know
Headlights all seem to be fine.
The failure is intermittent -- shutting the car off and waiting a few minutes seems to clear whatever is causing the fault.
I have a suspicion that all these things are related through a common connection, or relay, or something. The problem is, I don't have a wiring diagram of the vehicle to troubleshoot it.
Any suggestions as to what might be the problem?
thanks, Isaac
