hey fellas so i have a 1991 hatch that has no working brake lights, tail lights, or cluster lights heres a list of what i`ve done.
checked:
all fuses and relays in both boxes under hood
changed all relays and fuses in kick panel even the 3 behind fuse panel and 2 behind that white box above fuse panel
checked wires from tail lights all the way to fuse panel.
changed cluster
i`ve also changed every electrical box i could find behind kick panel
changed headlight switch
my headlights still work and i currently have the tail lights wired to a toggle switch in the main power wire at the tail lights before it seperates to the different lights. where my rear hatch grabber lock thing is there is no relay but there is in my friends 93 hatch i cant find any missing wires that would lead to it tho and my hatch wiper/defrost is unpluged as when i started chasing wires i realized a green wire had burnt up to bare wire and the defrost light stayed on so i unplugged that and have left it at that for now ANY HELP?
i still have radio its a factory am/fm/tape/cd cd player doesn`t work and the light on the radio sometimes work but usually not all the fuses are good to go i even replaced them incase im blind i also replaced all the relays i could find. the wires on the passenger side of the hatch are burnt from the plugs behind interior 1/4 all the way to the wiper/3rd brake light i just unpluged those three plugs before i replaced everything and i took the rear defrost switch out because it was staying on then replaced the fuses and relays and still nothing but i cant find any more burnt wires

Have you got a wiring diagram-if you do and you dont know how to read it I might be able to help you out.I am an electrician and I know it can be difficult for people to follow schematics-unfortunately its never easy to troubleshoot automotive electrical at the best of times-If you’ve replaced all your plug in shit-you are pretty much left with wiring-check for a shor from dash to the point where you power up the rears with a toggle-is the tcu sticky is refering to in the left rear pass side behind the plastics for the armrest(for lack of better words)-ive got a whole harness and all components from an 89 I stripped if anything will help you out let me know
I had this same problem a few weeks ago, as soon as i put my lights on the fuse would blow…after alot of messing around i found it was a wire in the front end near the turn signal shorting out…then it was fixed…ither then that start traceing wires is what i was told. lol
i used my voltmeter on the terminals getting 12-12.6volts and replaced the fuses also checked everywhere else i have no power going to back of the car or cluster lights have it at the fuse panel but thats it
ok so i took the car to napa they did a diagnostic check just said i needed a o2 sensor so replaced that replaced tcu replaced ecu the only broken wires i found were where the wires come threw the hatch and into the interior on passenger side one green wire was burnt to so i just disconnected them and left it at that my rear defrost button light would not turn off so i dissconnected it still nothing im stuck on using a toggle switch wired right to the rear lights…i hate wiring…
