2010 Headlight Moisture FIX!!
Corvette Dudes,
I have a 2010 Grand Sport that developed a moisture problem like you all have reported. I thought at first, that I would have the local Corvette Service Center evaluate the problem. OK, so they would replace the head light assembly for around $1600.00 plus the labor.
My response was, "not only heck NO, with some added expletives." and decide to resolve the issue myself.
To not be verbose, I will give you a quick fix that works OK.
Here it is:
1. Jack up the car and remove the appropriate side tire.
2. Remove the several "push-pins" that hold the inner fender flashing to gain access to the headlight assembly.
3. Remove the rubber seal that covers the electrical connector (for replacing the light bulbs).
4. With the headlight enclosure ventilated in this manner, the moisture was evaporated within a couple of hours sitting in the hot sun.
5. Allow the assembly to cool (like in the garage) and then apply clear external caulk to the rubber seal and the surrounding clear plastic headlamp cover (this, by the way, is the most likely source of the in-leakage).
6. Ok, now replace the rubber seal that you removed in Step #3 above after inspecting it to see if the seal also needs some sealant. Use a good sealant (moisture proof) that is removable should you have to remove the seal sometime later to replace light bulbs. !!!
7. Replace the inner fender seal using the "push-pins" and replace the tire.
Ok, Dudes you are DONE
