Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome! My name is ***** ***** I can assist you with your question. If you jumper the brake light switch, do the brake lights illuminate? What size engine do you have?
Jumper the Pink/dark blue wire to the tan/white wire
Does the high mount stop lamp work when jumpering these wires?
Ok, then I suspect the problem is upstream due to the low voltage going to the switch. Start by checking fuse 19 in the juntion box for power. Be sure it has FULL battery voltage on it at all times.
No.. wait... I take that back. It is fuse number 5 (20 amp fuse) in the power distribution center under the hood that feeds the brake light switch.
If this fuse has full battery voltage on it, then the problem is between this fuse and the brake light switch. If this fuse has low voltage on it, then I suspect the problem to be upstream of the fuse.. like a bad power distribution center or a bad connection at or after the battery.
No.. this is fuse NUMBER 5 and it is a 20 AMP fuse
Your not checking amps. Your checking volts. Just set it to the 20 volt DC setting
Ok, then thats good. This means we have succesfully narrowed the problem down. Since this fuse is good and have full battery voltage on it, this means the problem is between the fuse and the brake light switch.
Either the power distribution is bad or the wire from the PDC to the brake light switch is bad. I would check the wire first and replace it if there is a voltage drop from the PDC to the brake light switch. If there is low voltage coming directly out of the PDC on that circuit, then the problem is inside the PDC and the PDC is bad and need to be replaced.
I am glad I can help!
