When I start my truck the headlights come on but,
when I turn the motor off the lights stay on and not go off even after hours of sitting,
thanks,

This has auto headlamps? These are the headlights we are talking about and not the DRL's? There are relays in the underhood fuse center, try swapping out the A/C relay for the headlight relay or the DRL relay depending on which is staying on. If it fixes it, you have a bad relay, if not get back to me, might be a problem with the BCM ( Body Control Module)

I Swap out the relays and lights still on, All the lights not just headlights, Even when I disconnect tne light
switch, They are still on, After I disconnect the battery they go out, and come back on when engine is started again, Also I have to press the key remote switch before it will start does this go together,

Thanks,
Alan
