Re: HELP my F150 lights will not turn off
Mine is a 1991 F150 ex cab. Has been a great vehicle. Just had it painted, but have had no mechanical problems whatsoever and it has 120k miles.
As to my problem, I found a reference to a relay in the wiring diagram in my Haynes manual. I too, had about decided that was about all it could be. In effect, the contacts in the relay were not releasing when the switch was turned off. No, they would not go off after a short while. In fact they ran my battery down, because I did not notice they were left on. I did not notice they were on as I had them on during the day during a rain shower.
I will pick up a new relay tomorrow. Hoping this will solve the problem. If not, I will get back. In fact for everyone's info, I will post the result of replacing the relay.
