Lights

[bugsyc]

My fog lights don't work.My tail lights don't come on when I use my headlights...The signals work,front and back and the brake lights work...One of the corner lights was out but I put a new one in and still the same....I checked the fuses,they're good..I have no current to tail lights,there is current when signaling and braking....Anyone have an idea???I'm thinking light switch...FBM you out there???Rebuilt LCM installed last year..I hardly ever use the car....I had to use it today and I saw no tail lights...

It's possible it's the headlight switch.

But first..............

Make sure the LCM connectors are seated.

I went thru and did that,checked that the LCM connections were all seated....The only other thing would be the switch????Couldn't be the LCM I got from you???No problems with the headlights...Can I get a diagnostic code???

No diagnostic codes from the LCM.

Brake lights do not go thru the LCM - separate circuit.

If the turn signal work then the LCM is OK since the LCM is part of the circuit.

Check the following fuses:

Inside fuse panel:

#6 - 15A
#15 - 15A
#18 - 15A
#21 - 15A
#22 - 20A
#23 - 15A
#27 - 25A


Power Distribution under the hood, behind the battery:

#112 - 40A
#113 - 50A
#115 - 50A
#207 - 1/2 ISO


If those are good, I'm thinking either the headlight switch or multifunction switch.

Could also be a bad connection or broken wire somewhere.

All the fuses are good...How do you check #207???With my ohm meter I got closed from the top prong to the middle prong on the three in a row prongs along the top.. all the other combo's were open..Does that mean it's good or bad or what???

Here is a "how to":

You could also swap it out with the relay in #209 or #208 if you have a moonroof.

Thank you for the HOW TO...The relay checks good...I ordered a new switch...I doubt it's the multi switch in the column because all functions work..signals,high beam wipers etc...

Do you have power at the foglights? If not start checking back from the foglights.

I have seen some harnesses with bad corrosion in the black (ground) wire.

Will do and Thanks again for your help..

I don't know what happened but,I started up the Marauder today and all the lights work...I removed that lighted trailer hitch,maybe that was shorted out...Yesterday the foglights didn't work but,today they do...I,ve had the car covered up outside in my driveway for a month or two...Maybe some moisture or something messed up a connection..All I know is today everything works....
