Condensation in XC90 tail light

Post by anothevolvofan » Thu Jul 11, 2019 11:52 am

There's a condensation in left taillight.

I took taillight apart and dried it but after rainy day condensation reocurred.

How to solve this problem?

Check the lens carefully, it might have a crack somewhere that's letting the moisture in.

On mine, the epoxy backing of the bulb socket was cracked allowing water to pass. I sealed it up with silicone and all was good.
