Electric issues
My 2000 F150 is having headlight issues.

First i came out of the super market and my parking/tail lights lights were on even though i had the switch off and my headlights would not come on. I pulled the fuse so the battery would not die.

I thought it had a bad headlight switch so i changed it. Nothing changed still my headlights would not work and my parking/tail lights were stuck on.

So now i changed the multi function switch and my parking/tail lights go on and off with the head light switch but still no head lights.

Once i changed the multi function switch i went to test it by starting the truck up but all the idiot lights lit up on the cluster and my speedodometer had all dashes and the fuel relay is clicking and guess what it wont start.

Any ideas? I need help.

Thanks in advance Bob

Charge the battery and then check for ihe speedo and idiot lights. That's probably all it is. As for the headights, check fuses 26, 27, 28 under the dash and fuse 3 under the hood.

The multi-function switch has nothing to do with the park lights. In the park light circuit, it doesn't go through that switch. You must have some wiring connection problems. If there's an aftermarket alarm, they might have changed the wiring. Here's headlight diagram in 2 parts.
