What good are they then!They do not; they only come on when unlocking with keyfob. With the truck unlocked, no keyfob etc. opening any door does lower the running board but light does not come on. With the engine running and say you stop to pick someone up (especially in the dark), the running board lights don't turn on.
There was a lot of discussion on this subject a while ago.
Maybe I'm not stating it correctly. I feel the gm engineering should have designed the running board lights come on, whenever the puddle lights come on!
I wasn't trying to state that they are designed to come on with puddle lights, but that they should.
ETA... me and words don't get along sometimes!
