Default help with blinker with headlights on

HI

Having a problem with when I turn the headlights on the blinker instrument light on dash comes on for the drivers side with blinker off. and the blinker does not work with the lights on. With the lights off blinker works fine. It only affects the front drivers side signal.

any ideas. I cleaned the ground but made no difference

Just some suggestions you have probably looked at.

This acts like a bulb is out, I’m sure you have replaced them. Also look at the jumper harness for the parking lamp. Pull the connector apart and make sure it’s making good contact.

If one of the connectors is corroded or not making contact this would cause this problem.

Thanks Wilcox

I do have new bulbs but I will check the connecter for the parking lamps. I know the one you are talking about but have not pulled apart to check.

The turn signal filament and the parking light filament (in the same bulb-drivers side) share a ground.When that ground is gone the parking light filament will find its ground through the turn signal filament,backfeed up to the turn signal indicator in the dash.All that probably bores most people.....the black ground wire in the 3 wire connector going to the drivers turn signal is not making contact or the wire is broken.
Like Wilcox said clean the connector going to the drivers side turn signal.That should fix your problem.I find the easiest way is to dip the entire connector in a contact cleaning solution.(Dupont 5717S is what I use.)

Also for this mild acid, can this be found locally ? or is online the only
method to obtain.

Thanks

The Dupont 5717S is actually for prepping a metal body car, so a paint supply place would have it.Mine is very old and in a quart size brown glass bottle.I'm sure there are other products that will do the same job.Maybe an electrical supply house might have an actual contact cleaner.Maybe a hobby shop might have it in much smaller quantity.I believe the 5717s is a mixture and not just one acid.I wonder if you went to the Dupont site if they would say what it actually is.Some of the wheel cleaning products might have an acid that could work on contacts.
