Tip: The max point reward for answering a question is 15.
did you scan the PCM first.
rear lights dead, not dead dash brake warning light.
check all fuses first?
the fuse is in the cab or under hood
so lets find out where, i open FSM book, and look at schematic
the fuse is in JB box. cab fuse box.
its marked clearly as. Fuse F23 Brakes.
the brake switch is on the brake pedal.
if the fuse is good, 12vdc on both sides.at all times.
then the brake switch is open
if its output is 0v brakes pressed.
if the output is 12v then the switch is good, and the wire
are bad, to the rear.
or both lamps burned out or both sockets bad or wires cut
from trailer hitch hacks,.
There is a large maxi-fuse between the battery and alternator. Its at least 100 amp or more. It may be in the cable at the battery, or in one of the fuse boxes. You may also have damaged the key switch or the brake circuit. You may have to get a book to get the wiring diagrams to check everything involved.
hi it sound like a dead short somewhere this could be anythink check cable from the socket to the washer. check in the drum for bra wires these can short out on the element check the socket if all ok the may be a fault on the the washer spower board good luck
Check all the light "sockets" in the back,look for damaged wires, check the wire harness that goes to your tail end door for wire damage, you could try to reseat each bulb and when doing so look for corrosion in the light sockets. other than that,your center break light in back may have a control unit that may be bad and shorting out. you need to test things 1 by 1. good luck!
Hi from retired Englishman in SW France,
If the switch 'feels' OK it possibly is OK but it could be internal wiring/plugs sockets, control panel switches, control PCB, I fear that your only real option is a service call as the engineer will have the right equipment to safely diagnose what is wrong.
If the door switch is bad, it will override the system and shut it down. Also, check the plunger on the door that makes contact with the switch. If it is still there, access the switch and check the wires that are on the switch. Be sure they have good contact.
You could try pushing the switch with a pencil or small screwdriver and listen for a faint clicking sound, like a relay picking. This means that it is mechanically working, but a problem may still exist with the contacts inside the switch. Remove the two wires from the door switch (with machine unplugged) and place paper clip between the two leads. Tape securely. Plug the machine back in and see if it will start. If it does, this isolates the problem to the door switch and it needs to be replaced. Do not attempt to use the washer with the paper clip bridge.
