Got a 89 f150, replaced the switch the female end (that plugs into the switch). I am still having the same problem.... When I pull the switch out only the headlights work, I have to push the switch in a lil bit to get the parking light and tail lights to come on with the headlights. When I pull the switch out to just the parking lights they dont turn on. Please help!!!

 

Did you replace the switch or the switch end of the harness?

 

sorry i was tired when i wrote the post... i meant to say i replace everything the switch AND the female end that plugs into the switch

 

Ck. fuse #4, 15 amp at the fuse panel, feeds Tan/White wire to the headlamp switch. The switch should feed the Brown wire while in both tail and headlamp positions.

 

Ill be damned... It was that fuse. Thanks for the help

 

You're welcome, glad you got it.
