See if they turn off when you turn on the high beams. If they do, you probably have a bad combination switch with inoperative fog lamp contacts. If they don't, you probably have a bad IPDM.
whats an IPDMSee if they turn off when you turn on the high beams. If they do, you probably have a bad combination switch with inoperative fog lamp contacts. If they don't, you probably have a bad IPDM.
ok thanks, i had heard relay as well possibly?Not a fuse. The IPDM is the control box for most of the lights and power in the car. It's upside down at the back of the black fuseboxes that sit in front of the driver's side strut tower. It should be plug-and-play on a '17, no tools needed to swap it out. However, a new one isn't cheap.
honestly no clue, right now they turn on as soon as I start car. They do not look like bright ledsOn a '17 the relay is inside the IPDM, it isn't serviceable. BUT... Do you have two bulbs in your fog lamp housings? It just occurred to me, some of the '17's came through with LED fogs, but some came through with "split level" fogs like the '16's, which had separate fog and DRL bulbs sharing the same housing. If there are two bulbs in each housing then what you're seeing are peanut bulbs for the DRL's, the fogs will only come on with the fog switch on and the headlights on low beam.
I think you may be right, when I start the car with the brake enabled the lights do not turn on, once brake disengaged the lights come onThen see if they get a lot brighter when you hit the fog switch, I bet you have split levels and what you're seeing is DRL's.
