Sunroof slow

[mickey356]

OK, I must be completely inept when it comes to using the search function. I serached sunroof slow and sunroof slow close and could find the answer.
I replaced the cables in my sunroof today. It was hung up by the headliner piece that snaps to the underside of the sunroof (frayed and needs replacing). So I took the headliner piece back out and now the roof works fine going back but gets hung up half way on the closing return. A little help gets it shut but the rear doesn't move up without a little push. I almost seems as if the motor doesn't have the power to push it closed.
Background - I had to use "newer" cables with felt wrapped around them. I removed almost all the felt. Also they needed to be filed down a bit to fit in the channels which was no biggie to fix. They both guides slid easily in the channels before I installed them. I also lubed and cleaned the little gear that moves the cables. The motor works fine (or seems to) and the trans also seems to operate correctly.

did you grease the slider pieces? the ones that ride on the rails?
Mine was very slow and stickey, almost dead, and I greased those holder pieces when i took the sunroof panel out and it all works fine and happy now. hope this helps.

No Scot, I didn't grease them because I thought you weren't supposed to. I was under the impression that grease will collect dust and dirt and eventually clog up the rails. Was I supposed to grease the rails?

well, it worked for me... I just slathered grease all over ,,and wiped off the excess, but was sure to get some inside those little plastic grabby parts in the sliders, the ones that come off in your hands when you take out those two bolts.

I think that was it on mine.. worked all smooth and happy after that.

and this was with no new parts, just got it going for free.

I think this is why alot of owners have broken cables issues, cause the cables snap when there is too much resistance.

I did see something somewhere ( oh, in the bentleys manual) about dont grease the cables,, that makes sense,, but it didn't say you can't grease away on the rails and sliders.

I used simple white engine assembly grease, like for when you put in new cams. I've had it in my garage for 20 years or so I think,

Another choice might be to use a silicone stick. from the hardware store, used to fix sticky house windows and sliding doors,, I like that stuff, too

hope this helps,, give it a go.

Mine was doing that until I put in a new motor.

You can also try opening up the transmission and checking the viscous fluid inside. Also have a look @ the gear inside the trans. I've replaced mine.

Also check the clutch, which is that little cigar like coupling the motor shaft slips into.

And finally, have a look @ your seals around the sunroof. If they aren't tight to the roof opening and the panel, they could bind.

could search 'sun roof', not 'sunroof'

- what about gunk in the cable fuzz?

- adjustment off?
