The running lights are not working, however all the other lights are. My headlights, brake lights, reverse lights and signal lights all work. I have replaced the fuse, and the bulb, and it is still not working. I am pretty sure this is not a wiring issue because it was working a week ago. I am wondering if it is my switch because as a test, I left the switch on overnight and it did not kill my battery. The other thing I am experiencing is problems with my automatic seats on my drivers side only. The passenger side seat goes forward and back and reclines just fine, however the drivers side is no dice. Do you think this could be problems with a relay or something similar?

The lighting is likely a failed marker lamp relay. It is in the relay center in the end of the dash on the drivers side. Fifth from the top small relay on the left side. CMI5 To test it, just swap it with the one above it (that is the high beam relay), if the relay is bad and you swap them the marker/running lights should now work but the high beams wont. Just replace the relay. If the relay swap does not work then you have a fault in the wiring. That could take a while to find.

The seat issue could be a bad fuse (30 amp 11C5 5th fuse down, left side of panel next to relay panel for lights)
Or the wiring/connection under the seat has broken/corroded.
