Removed the sunroof section of the headliner from the back of the pan. Replaced headlier on this section and put it back in. Now, sunroof won't retract. The back end raises up ok, and it worked fine before the repacement but if I try to crank with the section in, its obviously stuck.

The installation looks fine. The tabs on the headliner section appear seated in the sunroof rails properly. The headliner is hooked onto the front of the sunroof as it should be. All else appears fine, it just won't crank. If I take the headliner section out again, which I did, the sunroof cranks just fine, so the problem apparently isn't in the crank mechanism or the sunroof proper. Im assuming there is something wrong in how I am reinstalling the headlier section, or I buggered the headliner up in some way.

Anyone have similar experience or ideas?

Headliner material too thick. Can't use standard headliner on sunroofs.

I used one-eigth inch foam backed material as suiggested many times in these forums. I used it on both the main board and the sunroof. I stretched the material very taught and there is no material overlap at all. In other words, I made it as thin as possible with the material I was using.

So what now? If it won't work with one-eigth inch material what do I use? I'm sure I can't get unlined material to match the foam backed on the main headliner board, and I can see that unlined material won't work well on the main headliner board.

Thanks for replies

Works fine as long as you use 1/8" material. Did you reattach the keeper springs for when it's in the vent position?
