The Car Care Nut replaces a sunroof in an instructional video and yikes!

[gil12]

I have had too many vehicles with sunroofs (starting with a 1961 Peugeot 403 wagon). I never wanted a sunroof, and (almost) never have wanted to drive with them. Last time I used mine was in Yellowstone while waiting for a group of bison to mosey off the road - then it didn't want to close - then it started to rain. A can of spray lubricant and two helpers (thanks Ian and Richard) pulling while I pushed buttons eventually closed it. I have since covered the buttons with tape.

Anyone have s suggestion on disconnecting the power to the motor so I can't accidently open it?

You can pop down the trim piece around the buttons and unplug the connector from the motor. I'm sure there's a fuse option too, just not sure if it's shared with anything else.

You may want to rethink that. Even if you don't ever use the sunroof - the drain channels may eventually clog up and flood the car from inside ruining the electronics.

You can always unbolt the glass from the rails and lift it directly up and off to clear the drains as needed. A disabled or nonfunctional roof doesn't mean you're stuck dealing with clogged drains.

 

[100s]

I developed a sunroof drain special service tool.
I do a full service on both of my 100’s and any (which is all) of our 5 cars, once a year.

Vac out debris, wipe down mating surfaces for the seals. Clean out as much crud as possible.

With the car pointed uphill, Load the special service tool with dawn power wash concentrate. Let this run through all four front and REAR drains. Follow with a low pressure water rinse. During the process I am verifying each drain point for each of the 4 drains.

I found that surgical tubing for a nebulizer fit into a necked down adapter for a little craftsman shop vac. The tube is just rigid enough to actually gently move through the front drains. With an endoscope I can navigate to the rear drains and flush them. The final flush is a low pressure blow out using water to rinse. Just turning the hose to the “output” on the little shop vac. The hose doesn’t completely fill the drains so there is plenty of space to avoid putting too much pressure on a fitting and blowing it apart behind the trim.

Lube cables with lithium grease, point car downhill in hopes it makes its way through the tubes up front.
