I'm looking for suggestions on how to find a problem relating to the #21 fuse which continues to burn out.
I first noticed the problem when I got in the vehicle and the dome light did not turn off. The dome light normally has a delay and then turns off after about 20 seconds. I also noticed that the clock and trip milage gauges were out (they usually stay on when the van is off). The Instrument cluster lights were out and the radio wouldn't turn on. In addition, I later learned that the OBD II scan would not work.
#21 Fuse is connected to...
Instrument cluster, interior lights, radio, B+ (battery positiv voltage) for on board diagnostic
I've started by testing the door switches. All of these seem to be making good contact.
I am not sure how the delayed dome light works and wonder if this is a relay of some sort that might be the culprit?
Any suggestions for finding this short??
