Here's one thats got me scratching my head. My front right blinker went the other day so I replaced the bulb. I noticed that the socket looked like it might have gotten hot, it was brownish in color. I replaced the bulb and it worked for about a week then went again. It seems like that circuit is drawing too much current but I'm having trouble understanding how that could be possible because usually the current is limited by the resistance of the bulb. Does anyone have any ideas? Any help would be appreciated. Thanks in advance.

 

If the bulb contacts in the socket are loose,they will arc,creating resistance( high current draw) and heat(toasted socket).
Clean up the contacts in the socket,and see if you can tighten them up .
I'm not sure if you can -,I've changed a few bulbs,but haven't noticed if you can do anything with the contacts or not,perhaps someone with experience at this will chime in...

 

The normal issue is that the heat from the DRLs weakens the lamp housing and eventually it cracks allowing water into the unit. That causes arcing and you see the result as a brown mark.

Pull the lamp unit and check it over. You'll probably find a hole which you can seal with sealant.

Heres a How To

Installation Procedure
1. Install the front park/turn signal and sidemarker lamp into position on the front turn signal lamp bracket.
Notice
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
2. Install the front park/turn signal and sidemarker lamp to bracket retaining screws.
Tighten
Tighten the front park/turn signal and sidemarker lamp to bracket retaining screws to 2 N•m (18 lb in).
3. Install the sockets to the lamp.
4. Install the lamp, with the bracket, to the front fascia.
5. Align the lamp to the opening in the front fascia and hold the lamp firmly in place against the fascia, while installing the front turn signal lamp bracket retaining screws.
Tighten
Tighten the front turn signal lamp bracket retaining screws to 3 N•m (27 lb in).
6. Install the lamp bracket retaining spring to the front fascia.
7. Install the front turn signal lamp bracket retaining spring to the lamp bracket.
8. Position the brake caliper cooling duct to the front fascia and press the duct toward the fascia to secure.
9. Install the front fascia lower closeout panel. Refer to Close Out Panel - Front Bumper Fascia Lower in Bumpers.

 

This is what I suspected. I think I would like to just replace the socket. Does anyone know where to but a replacement socket, or is that just a dealer item? Probably a dealer item I suppose. Thanks for the help.
