Just bought this truck a few weeks ago and can not figure out the headlight issue.
They will only work when the key is on. The switch is not operational what so ever. I just put a new switch in it this week after testing all the wires at the plug and still have the same issue.
All the lights work and function when the truck is running. Ive got voltahe at the switch so I dont believe this is TIPM related. The dimmer nor cargo light no not respond to the switch motion either.
Ive checked the DRL sensor aswell as reset the computer by pulling battery cables and grounding them twice. Still nothing.
Does anyone have any ideas where I should go from here besides the dealer?
Aside from being deleted with EFIlive, it has aftermarket cab lights and dealer installed remote start.
Cab lights work and pull signal from the orange/brown tow circuit at the headliht switch hence, how i know the TIPM is working.
