I picked up a 1987 Comanche 4.0 5 speed last week. The following is a list of the stuff that didn’t work. blower motor, radio, clock and turn signals.
I checked and cleaned all the fuses under the dash. There were multiple blown fuses so I replaced them. After replacing the bad fuses everything worked I had blinkers, clock, radio and the blower.
Last night I noticed my dash lights where out when I turned my headlights on. then as I was driving my windshield wipers cut out. When I went to drive to school this morning I noticed I also now have no turn signals or radio. I just checked all the fuses under the dash again and non of them are blow.
The blower motor and hazards are the only things working.
Notes: Sometimes radio flashes on for just a second when I turn the truck off. Clock only worked if I didn’t have the headlights on. when I first “fixed” the blinkers it would take a solid 2 seconds after hitting the switch for the dash indicators to work and they would speed up faster and faster the longer I had the blinker on. Also there was a time when the blinker was blinking but very erratic and dim (on dash).
