My right front DTR/turn signal light keeps burning out and frying the socket. Checked the voltage and it seems ok. Any ideas?

Thanks

 

Are you putting LED's in them or regular bulbs?

 

Is water getting in there?

 

regular bulbs, stock sockets from the GM dealer. This is the third set in 4 weeks.

 

No, it has been dry here until today. No rain or water to affect the lights.

 

The DRLs burn the housing which lets water in. Even though it hasn't rained you'll find water gets in there when you wash it.

You need to pull the housing and inspect the plastic unit for damage. You also need to check the connectors for dirt and corrosion. If the housing is burned you can run a bead of silicon sealant to fix it.

I'll dig out an old post and post it up

 

Melted turn signal housings are common and its a design problem on all C5s. The turn signal bulbs are dual filament and act as park, turn and DRLs. The heat of the DRLs being on constantly burns the housing. I had to inhibit the DRLs here in England as ambers are not legal here. I never have T/S bulb failures and my lenses are still sound. The most common symptom is that the bulbs fail regularly because water gets into the bulb holder.

You can inhibit the DRLs by pulling the A2 fuse but if you want to keep the DRLs, LEDs are the way to go. LED bulbs produce less heat and are less likely to damage the housing. If you fit LEDs you’ll need a ballast mod to prevent “hyperflashing” as the system doesn’t recognize the LED bulb and thinks it’s failed. (JWMotoring sell a harness which will fix that issue).

Pull the housing – I’ve attached a procedure below – and inspect it. Others prefer to go in through the headlight housing but its harder to see the fixtures. You’ll probably find a hole on top. If it’s not too bad seal it with silicon sealant and reinstall the housing. That should fix the problem for now and the silicon may be enough to stop it getting worse.

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

Thanks for the article and your time searching. I will try a sealant. I have not found any cracks but I know if there is a opening water will find it. I appreciate the information.

just an idea but, just make sure that the bulb "snaps" in socket...I chased that issue also and found I haven't been connecting it properly....good Luck
