So I have no tail, dash, or front bumper lights. Does anyone have some suggestions on where to begin?

 

Fuses?

 

Checked the ones under the dash, they're ok. Has to be some other place where they are all linked.

 

If your dimer isn't plugged in y our dash will not light up. <-- learned the hard way.

 

You need a new headlight switch.

 

Thanks, I'll check it out.

 

But the headlights do work. I would think if it was the switch they wouldn't work either???

 

Check for a pinched off line. It can ground on metal and kill the lights. This happened to one of my wires going to the ash tray that I use to power the gauges. Fried a fuse, too.

 

bzwigert, did you find a solution to your problem? I have the exact same symptoms.

 

Solution: Blown taillight fuse.

 

I have the same problem. Its driving me nuts. I can't seem to track it down.

The "tail" fuse blows a few seconds after turning on the lights. This fuse powers the dash lights, bumper lights and tail lights. Not sure what the problem is. I checked the ashtray wiring (I'm tapped into this to power the boost gauge lights). I removed the boost gauge, radio (newly installed) and everything else I could think of and I STILL have the problem. The headlights still work - they are on a different circuit.

I ordered a new TNS relay which is also part of the tail light circuit. If thats not it, I'll give up and have Dave at KD Rotary attempt to track down the problem since the car is going to KD in about a week for a few maintence item replacements and upgrades. I've spent hours trying to track down this problem.

 

what this is is the relay box we have under the hood on the rad. support...there is a tns relay in there....it causes all that....i have fits with mine all the time....specialy when it rains.....
