I checked the sunroof issues thread and it didn't really cover what's happening for me. You know how it goes, my power sunroof is being grumpy. Symptom is simple: You gotta REALLY jam on and spam pressing on the switch buttons to make it do anything, but when it does work it moves part (or more rarely all) of the way, this is true for both back and forwards. When it doesn't move I still hear a click when you press the buttons, I think the relay is actuating but nothing happens, no motor whirring or straining noises. When it was in for other work my shop of choice advised I try and clean the contacts and such before I bothered replacing the relay itself or the motor. The motor seems operable, the sunroof doesn't seem physically jammed when it does move, and I've used multiple known good switches and they all have the same result so my hunch is contacts, relay, a gear out of whack, or something is screwy with the travel stop switch thingy integral to the motor assembly. I also looked in my Bentley manual but it was sparse - plenty of info on how to service the sunroof mechanical components but nothing I saw in the way of how properly remove the visor headliner hard panel without damaging it. The little access cutout for manually traversing the sunroof with an allen wrench isn't big enough to really get the relay out or get at contacts to clean 'em, either.
I know the visor screws gotta come out but apparently there's also screws that are harder to get at elsewhere, but I'm a little foggy on the details. To my understanding a common way involves partially removing the door seals but given their difficulty to get proper replacements and the fact mine are original and intact I was hoping to avoid putting them through undue stress or cause any damage to them. Likewise I'm leery of trying to disassemble the roof mechanisms for lubrication or repair given their infamous pain-in-the-assness and how rainy my state is. There's also some minor bubbling at one part of the sunroof panel itself though thankfully not the roof so I want to address that as best I can and ensure my sunroof drains are cleared out and to check for any corrosion in the cassette, but that's a hell of a lot more of an endeavor without being able to open and close the thing consistently - hence the desire to eliminate or resolve the electrical stuff first.
Anybody got pointers? Feel free to move this to the electrical area of the forum if it makes more sense to put it there, mods. Thanks.
