Clinton's right. My passenger side socket is all crusty and burnt looking. I've also heard this on other forums.
I wiggled the socket a few months ago while changing the headlights out, and presto! Working DRLs again! Never did burn a bulb out...
Overall my 04 GMC has been the best vehicle I'ver ever owned, but one design flaw it has is cheap wiring. Electrical components seem to be made to bare minimum standards and are operating at 100% without any factor of safety. By far, the most repairs I have done to the truck have been electrical in nature and usually caused by tiny wires that have broken or shorted. So far I've fixed:
- An air bag sensor connection below the driver's seat. Wire broke at the plug. Couldn't repair, had to replace the entire seat harness.
- Headlamp socket.
- Rear tail light connection point below the bed. Had no operational brake or directional lights.
- Tow haul button wire broke. Had to replace the shifter.
- Cigarette lighter burnt the center connection. Replaced the lighter socket.
- Accessory socket, same as the cig lighter.
- The occasional fuse.
- 4wd switch.
- 4wd actuator encoder motor (twice)
- Fan motor resistor
- 2 body/chassis grounds
I've kept up the charging system as well, with a new alternator (at 150K, thats not bad) and a fresh battery every 3 years. I clean all connections at the battery, plow connections and trailer connections and liberally apply dielectric grease each year too.
