coman Posted February 2, 2020 Posted February 2, 2020 OK, I am tracking the problem down. The symptoms: No horn, blinkers, radio, heater/ac or wipers. They all used to work and they all stopped at the same time. The truck runs fine. The flashers work fine. Fuses all tested for continuity. Horn replaced, Blinker switch removed and cleaned. Radio lights up only for the eject function then goes dark again. Other actions: Remove C101 Refresh grounds: drivers side under dash and near the washer tank/air cleaner. Passenger side both at blower and near the relay bank. Engine (center) to firewall. Engine block stud, (2 wires here). I reviewed the diagrams supplied by hosts and others (TY). A bad ground seems likely or a common power relay? Any others thoughts? TY in advance.
Ωhm Posted February 2, 2020 Posted February 2, 2020 Do listed components work with the KEY in the ACC position?
Jeep Driver Posted February 2, 2020 Posted February 2, 2020 Just because a fuse is showing power across the fuse does not mean the power is passing through the fuse block. IOWs, corrosion on the back side of the block.
cruiser54 Posted February 3, 2020 Posted February 3, 2020 Brown wire at ignition switch is melted and switch is history.
cruiser54 Posted February 3, 2020 Posted February 3, 2020 Overloaded brown wire circuit sends power to all these: "No horn, blinkers, radio, heater/ac or wipers." Wire gets hot, melts. switch fails.
coman Posted February 11, 2020 Author Posted February 11, 2020 Pics and praise.... Everything works now except the horn. Almost ready to sell. Thanks Cruiser54. Case closed. Hail Comanche Club!
