On my '69 Firebird, with the headlight switch off, turn signals work fine, but when I turn on the headlights switch, weird things happen. The lights in the dash for the turn signals work opposite, as well the high beam light flashes too, outside they work as they should. Now, when I turn the high beams, the turn signal lights in the dash light up constant, but the high beam light doesn't, and the turn signals don't work at all. Now, I'm assuming some wires are crossed with the high beams and turn signals, but I was hoping for some input before I try and pull the dash apart this weekend if I get time. Thanks in advance!

Check the grounds, especially the headlight ground at the radiator support.

I don't think it's the headlight circuit, I think it's when the parking lights come on. Where's the ground for them, same place?

If you've got bad grounds there is no telling where ground is comming from. It can go through one circuit and ground through another. It gets quite complicated and confusing. Just make sure your grounds are good.

If the grounds are ok I would try checking the bulbs and bulb sockets also. Awhile back I had a chevy pickup in the shop that had a similiar problem. With headlights on and blinker on, the dash lights and other lights blinked with blinker.Turned out to be the bulb socket for one of the front turn signals was shorted internally.I replaced the socket and all was well again.

How did you know the socket was shorted out...bulb not working?

It didn't always do this, at least not when I bought it...started slowly getting worse and worse.

I finally found it by unpluging the sockets one at a time while trying the blinkers.When I unplugged the faulty socket the dash lights no longer flashed with the blinkers.Electricity can do some very strange things sometimes.You may even have a turn signal bulb that has the elements shorted to each other causing power to backfeed into another circiut.Id try unplugging the signal lights one at a time and see if it changes anything

I also remember working on a mid 80s Chevy pickup that the turn signal indicator would glow when the lights were turned on, that one turned out to be a ground wire loose on the radiator support.I cleaned up the conection and all was well again.Quite often its a bad connection someplace.

I seem to recall having a problem like that in one of the 69 Firebirds I had. Just as the 67- 68 Camaro’s instrument cluster grounds at the screw above the high beam indicator, the 69 Firebird’s instrument cluster grounds at a stud at the bottom right of the plastic dash, somewhere to the right of the ash tray.
