Headlights shorting out stuff

[Gregalexie]

I have a 96 and when I turn the headlights on it shorts out my drivers side rear blinker and the cruise control but if I turn them off they work just fine. I checked the fuses and they're all fine any ideas?

What happens when you turn on the parking lights?

[Gregalexie]

The parking lights work when all this happens

[madpogue]

That wasn't the question. When you turn on JUST the parking lights, NOT the headlights, does that cause the turn signals and/or cruise to fail?

[Gregalexie]

Yes just the left blinker though

The first thing to check when you have wierd electrical problems are the grounds, and not just one or two of them but all of them. A bad ground will cause backfeeding problems through other lights and all kinds of wierd problems.

^^^^^^ +1; start with the grounds for the LF turn/park bulb socket, and the LR turn/park/stop bulb socket. Also check both those bulbs, as a burned-out filament in a two-filament bulb can cause stuff like this.

I unplugged the tow light connection and everything is back to normal. Now I just gotta figure out why that's happening! Thank u guys for the help!
