You sir, have just joined the famous club called the, "You just literally exploded your DRL's to a carwash" club. Ok, I made that up but seriously, I'm posting this because not only was I a victim, I did it twice and it took me nothing short of a week to order replacement corner housings with LED's from JWM.

Check your corner housings. Wouldn't surprise me one bit if you have amber shrapnel bouncing around in there. This is common actually. The stock DRL bulbs are BRIGHT and HOT. They burn a small hole in your plastic light housing and that's where high pressure (not just rain usually) water goes. Cold water on hot bulbs... You can figure out the rest.

Buy replacements or I strongly recommend LED's. Trust me, this doesn't get better on its own. I have thin wrists so I was able to squeeze my arms down while the head lamps were up, to replace the bulbs. Hurts like hell but it's doable.

Be careful when pulling the bulbs. Seriously. They are actually shattered or have holes. So wear gloves.

I am sorry to hear you went through this. Trust me, I feel your pain.

Good luck!!!!

You can repair your current lamps... There will be a hole melted in the top of the
housing.. I used RTV (silicon) to plug the hole/holes.. I did both sides and then replace
the bad bulbs. It's cheaper than LEDs or new lamp housings. And not all that hard to do.

Changing the bulbs wont fix it. The DRLs have burned the lamp housing. You need to fix the root cause.

Heres the full procedure for replacing the lamps. I'd go in through the floor for this job whereas I go in around the headlamps to change a bulb. If you get in there and find you can use sealeant all the better

Its a 4157NA bulb but a 3157NA will work.

This is just a really bad design that needs to be corrected by each owner and not just keep replacing bulbs.

Go with the switchback LED's and fix the holes in the top of both corner housings. You will be shocked at the holes literally melted out of the housings. I used a small piece of aluminum sheet over the hole and then heat rated RTV sealant. Buy the LED's, hyperflash adapter and be done with this bad design by GM. They should have recalled this and I am surprised there were no fires from it. Maybe there was.....

I would use a small piece of sheet metal and some epoxy rather than silicone because of the high heat.

SUCCESS! I have fit my hand through and changed the bulb. I found a spare light bulb in my garage it says its a 405A and it ended up working! =D so.. as of now it stays in the garage away from water till I have the time to patch up the housing.

Thank you all for great input. You have all helped me very greatly!

At first I just repaired the DRL damaged housing so the water from the car wash didn't leak inside the lens housing but then I figured what the heck and just ordered a set of new lenses fron Eckler's.

Looking at the design of the light, can't you just remove the housing from the bracket and leave the bracket bolted to the car, looks easier to me? Anyone do this? Pros/Cons

I don't really remember how hard it was to get to those two screws on the bracket but getting the two screws out the way the instructions outline is pretty easy to do.
