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

Sounds like the BCM is having a problem. Might want to have it scanned for any codes that will help us figure this out
