Anyone else dealt with this? It's annoying having that little cap bouncing around in there. BOTH of mine are off. What got me motivated was that I had the door to the passenger side missing on my car. Went thru some high water and a little water got in there and exploded the bulb.

So.... with WATER in there, what to do? Well, I took the assembly right out and guess what? You can take the thing apart, put the cap back on, clean it all up inside - almost like new!

I can take some pics this weekend and do a write up, if anyone cares. All you need is a flat blade screwdriver, a T25 Torx screwdriver and a jack and tools to take the tire off so you can get IN there!
