ok dont laugh new owner, what turns on the factory fog lamps? there is an aftermarket light bar on the roof
that is turned on from a switch in the overhead console. i believe when i read online owners manual that was where the
switch would be? so both lamps were unplugged when i bought truck. connected them still dont work.
looked in under hood fuse box seems im missing a relay that is marked fog lamps or maybe aux lights? tried swapping a relay from wipers. no good? is there also a fuse for lights? havent had time to check for power at lamps. obviously both lamps could be bad.
also horn doesnt work. i here the relay click underhood. i swapped that relay still doesnt work again havent had time to measure at horns, could be 2 bad horns.

thanks

 

There are no fog lights on an H2..... There are comically gigantic DRL's (daytime running lights) that many new owners quickly find out about though. The fog light fuse in the underhood fuse box does nothing and is just there because the same fuse box is used on GM trucks and SUV's.

 

ok thanks so my daytime lights dont work should they automatically come on if i leave switch on auto setting?

 

Yes they should come on.

Also, overhead console light switch turns on the optional OEM roof light bar on the special editions like mine.

 

make sure the bulbs are not blown. might be as simple as that.
