I just bought my first toyota. its a 91 4runner 4wd V6. runs pretty good except for one thing. my parking lights and gauges aren't working. fuses are good, blubs are good, changed the combination switch, i have continuity across the dimmer knob. don't have power at the fuse switch or dimmer. i have the chilton manual but i cannot find a wiring diagram of this circut anywhere. it would be very helpful in finding the problem. what should i do?


edit: I did find a wiring diagram that helped me out a while ago.

 

so right after i posted this thread i figured out that my truck IS supposed to have a taillight relay and it wasn't there. replaced it and they still don't work. i re tested everything. have power at the comb. switch now and the relay is clicking on and off. have power at the fuse and the fuse is good. i checked the glove box switch plug and it does not have power but the power wire has continuity to the body. should i be looking for a damaged harness under the dash? i really didn't want to take the whole dash off but its looking like i probably have to. would the glove box power wire having continuity like that mean a ground short? its not popping any fuses so i'm not sure what to think.

 

have the dash out checking things out. no visible damage to the harness. still can't find anything helpful though.

 

well. i guess its a bad wire. don't think its a bad component. probably a cut wire or a screw through the power wire or something.

 

found it! finally! just gotta put a new plug an a little bit o wire to the license plate. wish i'd found it sooner but it coulda been worse.

 

so it was the liscence plate light.

 

hmm, i dont see how the license plate light was affecting all that if the fuse wasnt blowing. But if its fixed good job to ya

 

the fuse did blow after i put the relay in. i guess the PO removed it to keep the fuse from blowin. i don't know wtf was goin on but its working now. now i just gotta fix the p/s leak and figure out why don't have near the power i should. think my timing belt might be a tooth off. gonna check that this week.
