dash problem
 

Hey I have a major bug inside my dash somewhere. Everything works just fine until I turn on the headlights. First, the dash lights dont work at all, but they do light up when I start the car and the headlights are not on. Also all my guages take a crap, and the tach flutters when I turn on a blinker. Also the turn signal indicators are always lit up when the headlights are on, but they arent on. The blue high beam indicator is lit when the headlights are on but turns off when the high beams are turned on. Does anyone have any idea what would cause this. I swapped all the switches with the ones from my 91 GT and all are fine. I also checked all the fuses and they are fine. I also went as far as to swap the alternator in case that was a problem and it didnt help. It drives me insane because at night I dont know how much gas I have, my temp, oil pressure, rpm and I cant see the speedo with no lights in there. HELP! Thanks, John

Go back in and check all your grounds and use a multi-meter if its available.

Good luck!!

Man Ive checked every ground I knew of, but maybe I missed one. Im about to rewire the whole ******* thing. Thanks

how's your voltage?

The voltage is fine, Ive never had a dead or dying battery, even sitting at idle with the a/c on with underdrive pulleys. None of my buddies have ever seen anything like it. Oh yeah I forgot to mention, I my wipers work if my headlights are off, but when they are on........no wipers!

What year is it?

Take care

Its an 87

I can't remember, does the '87 have a multifunction switch in the steering column (lights, turn signal, wiper, high beams, all in the steering column)?

Yeah it has the same layout, the headlights are a switch on the upper left corner of the dash, but all the rest is like you said, just like on the later models.
