Clearout your message box so that you can get pm's.....


Anyway,Everything is working now except the taillights....turn signals,hazard lights,brake lights all good....headlights yes taillights no...I'm guessing that eliminates the multifunction switch????Due to the taillights not going thru it....So,It must be either the LCM,which FBM has kindly sent out to me.....Or the headlight switch(I'm hoping the LCM does the trick).....I wanted to thank you for your help privately but,your message box is full.......SO,thank you for your help....

Your welcome and no thanks on the PM box lol. I prefer to keep it full. I only empty a few slots when need be (like for you)

Check for power coming out of the headlight switch for the parking lamp circuit, it is the wh/blk wire.

It goes from there to the LCM and comes out of the LCM as a brown wire that branches off and supplies voltage to the front and rear parking lights, plate light, and the clock. So if the others work.... Then you have a short between there and the lamp or a bad ground. Pull the bulbs and check for power, ohm out the brown wire from the LCM to the lamps, ohm the ground. Plenty of stuff to start with. [emoji106]🏻

What are parking lights????never heard of them....There is no power to the tag light,if that helps...

[justbob]

Parking lights, tail lights, low side of the bulb, whatever term you feel fuzzy with.

Too many idiots out there assume you mean brake lights when you say tail lights.

Also mentioning the plate light helps narrow things down when getting help online. What about the clock? Test what I said to test in the order I mentioned to narrow it down.

Raining right now..I'll test tomorrow... taglight not working either....So,it's tag light and taillights only....All other lights good...

If the clock is lighting up when you turn on the parking lights then your headlight switch and the LCM should both be good according to my diagrams. Problem is elsewhere.
