The roller in the car wash bent the small rubber nipple and made a slight dent in the roof behind it. The rubber of the nipple was slightly cracked but I didn't think much of it at the time and put it in the top 1/3 of my to do list. So last week I finally got around to fixing it. I had parked the G outside overnight, something which rarely happens as I like to have it garaged. Some pure Oregon rainwater entered throught the crack in the rubber and collected in the dome light. When I drove to work in the AM and went around my first corner I had some water dripping down much to my dismay. All of a sudden it was at the top of the to do list.  Access to the underside of the antenna is easy, pushing the entire domelight unit forward toward the windshield and pulling down on the upper edge. The antenna boot has an integrated grommet and can be pushed down into the cab. The dent pushed out easily and the antenna boot was replaced in the hole using some clear silicone sealant around the base. the dealer sold me a new cover which goes on top of the original boot. It is slightly more prominent than the original piece and has an internal flange which interfaces with the groove near the base of the original nipple. All told, it was a very simple and easy repair. The headliner did not get wet as the water that did get in must have dripped directly down into the main dome light clear plastic bowl. Lucky. The silicone was the "shower in 1 hour" type, but as it started to rain about 5 minutes later I had to pull it into the garage.

Too bad you did not document the damage at the car wash. They would have paid for the entire repair. Back to hand washing. The car wash was not a good option as I had already lost my receipt to a half full cup of coffee and the repair seemed less of a pain than small claims court or dealing with... Since I drive my car, like, all the time, handwashing is not the best option for me. I was initially hesitant to post the repair as it seems kind of simple, but thought it might be nice to show what is behind the dome light and easy access to add a GPS antenna like Harald did or something like that. In reality, it is not much harder than changing out a side marker bulb except no tools are required. The part number for the boot is 202-827-00-31. Full retail at the dealer was $13.00, probably cheaper through some peoples sources.  | |

Future source of leaks. (PatioChairGlide.JPG) Attachments ---------------- PatioChairGlide.JPG (116KB - 30 downloads) | |

There are pretty nice through glass antennas that can be applied to the bottom of the windshield. I was thinking of going that route in my VW Bus https://www.amazon.com/dp/B013X8T8BC/ref=asc_df_B013X8T8BC5148447/?t...

I am pretty sure the hole is 3/4" as the patio chair glide was that size and fit perfect. There should already be a coax cable going up to the roof from the center console, although it may not be the right size for a HAM radio. Would be cool if you could reuse it. If not it can serve as a pull wire. | |
