when i turn my lights off, the running lights stay on. I have already replaced the switch and its not fixed... what else can I do to find the solution?

 

Do you have a multimeter? What year f150

 

I can get a multimeter, and its a 1997 f150

 

When do the headlights turn off or are they always on? Have you done any recent mods or when did this started happening?

 

I got the truck like that... the guy failed to tell me. I can turn them on just fine. but to get them off i have to undo the battery. they dont stay on all the time. just when i turned the switch. and i dont know of any tests to do or anything.

 

So if you disconnect the battery and reconnect it, they are off until you turn the switch on ?

Is it when you turn the headlamps on, or it does the same thing when you turn the parking lamps on ?

Do you have DRLs on that truck ( if so, factory or aftermarket ).

Are there any modifications to the truck when you got it ?

 

Have you checked the DRL relay? Sounds like its bad

 

All I know is the guy had subs hooked up to it at one point. The radio is messed up to but I dont care about that. And is there anyway you can tell me where that DRL relay is?

 

passenger side dash

 

Ok thanks alot

 

How is the radio messed up ?
- Have you tried pulling the fuses for it ?

forgot to ask, does the truck have autolamps ?
