Headlight switch crazy!
Headlight switch crazy!
My 91 f150 headlight switch does not turn on the parking lights at the first pull out slot but if you pull out alittle passed the setting as if you were to turn on the headlights they would come on. To make matters even worse. If you pull the switch completely out to turn on the headlights the parkinglights turn back off. Now catch this. If you push in the **** a hair or so as if you were turning off the headlights the parkinglights will then come back on with the headlights but will wiggle themselves back off after a few bumps.
I purchased a new switch and installed it but still have the same problem. I electrode tested both switches and they show no problems so I figured i would test the wires in the wiring socket that plugs into the switch and they also pass the test.
Pulling my hair out over this doesnt work either. Im stumped. Any help sure would be appreciated!

Well, I am positve now that its not in the switch. Just purchased another new switch and still has to be fumbled the same way in order to work.
I have a Haynes book on my truck and studied the wire set-up. The only way I came up with in my mind was, inorder to get the parking lights on was to have it ride particially on the headlight positive within the switch. As if it were feeding off the same positive as the headlights. I wouldnt think that would be possible but its all i can come up with. Testing showed connectivity between the two terminals but couldnt find a positive wire within the two when I checked with a test light. I wish the Haynes book would go into more detail of whats pos and neg on the diagram. Unless it does and I not know how to read it. Thats possible. Anyone else have an idea of what may be causing this grimlin before I give up and just pay for someone to take away my headache?
