why does my drivers side turn signal keep popping ?

 

Your light has a hole in it, it allows water to hit the hot bulb and break it.

You can fix it with some sealant. Remove it and fix it.

 

ill check it closer but it doesnt seem to leak or have a crack or hole in it

 

you probably won't be able to see it until you get the lens out.

among other reasons why you should disable your DRLs...the DRLs on C5s keep your turn signal bulbs lit in bright mode all day long. the heat from the bulbs is well known to melt and eventually cause a crack in the turn signal housing directly above the bulb. once that happens water will enter as soon as it rains and hit the hot bulb causing it to go.

seal the hole, replace your signal lenses with some nice clear ones if the damage is too bad and disable the DRLs or it will just happen again.

 

Yup, look right above the bulb. You can see it from around the headlight. There is a round hole in a gray piece above the white lens. It burns through right there.

To fix it just cover it with silicone or put in Depo corner lights and then install LED's to keep it from happening again.

This might help when you get round to pulling the light unit
