My taillights and sidemarkers are not working at all! My headlights, turn signals, hazards, and brakelights work though. All my fuses are good and the bulbs themselves are good. Someone please help! Thanks

 

Are you sure all your fuses are in good shape? I can think of the Switch being the culprit

 

I tested all the fuses with a fuse tester. If the headlights come on though the switch must work right?

 

If your metering fuse Is Intact than you need a new Left Instrument Cluster Headlight Switch. I had one priced out, for kicks, $647 can when mine went.

 

i woulda said fuse..when my fuse blew, headlights etc. worked..but the taillights didnt.

 

darkwaveboi: Which fuse went?

 

I had the same symptoms as you darkwaveboi (no dash lights, no tail lightsbut i had good side markers and headlights) but mine was a bad switch that was burning up my light switch harness. I ended up replacing both.

 

I agree. Check the harness and switch. Mine is doing the same thing. You can temporalily resolder the circuit board on the switch. Its best to go to the junkyard and get a new harness and switch. Check also to make sure your light sockets arent shorting out.

 

Where is the harness and switch?

 

i had the same problem ..im 90 percent sure its your headlight switch. ...you gotta take out your instrumental cluster out and take out the headlight switch....its most likely burnt out. replace that....very common replacement on the sevens.. 10 min job

you can buy one on ebay or on the forums for around 10-20 bucks... =)
