'92 900S-3 dr hatch-5sp w/153K. This past Saturday, the electric sunroof opened but would not close the sunroof panel-not good with rain threatening. Pulled it into the garage and tackled the problem Saturday. Here's how a trouble shot the reluctant sunroof panel, some additional proglems & how I resolved the original and subsequent problems.
I carefully *popped* the power window and sunroof rocker switch panel out of the center console with a flat bladed screwdriver and disconnected the wiring harness. This was super easy. I took the switch panel into the house and worked on it on newspaper on the kitchen table to minimize loss of little springs and copper connectors. I carefully pried the panel box apart, it separated into three pieces. Nothing broke or dropped into the black hole of tiny screws, nuts, washers and socks. I used alcohol swabs to clean out all the black gunk and used sandpaper and a toothbrush to clean off all the copper connectors. I even used dialectic tune-up grease on all the electrical connections. I carefully reassembled the panel and reinstalled back into the car. However, still no power to the roof. Hmmmmmm……
I again removed and pried apart the panel and upon further visual observation, noticed that one of the sunroof rocker switch *plungers* was worn down to the point that it was not providing the needed contact on the copper connector beneath that completes the circuit. I remembered I had an old window switch from my ’86 which I immediately cannibalized the old plunger and spring and installed into the new switch panel. Back into the car and SUCCESS, the sunroof closes but now the windows don’t work. Arghhhh!!.
Back to the kitchen table to pry apart, clean, reassembly and try again. Back into the car and still no windows. Maybe it’s a fuse. Ahah!. Check the fuse box under the rear seat and sure enough, the #7 window fuse had been blown, probably during one of my panel breakdown and reassemblies where I had not aligned one of the copper connectors correctly.
Moral of the story: If at first you don’t succeed, try, try again, then check the easy stuff like the fuse panel. Spurred on by my success, I later tore down the driver door and lubed the sticky power window assembly. Now nice quiet and fast power window AND sunroof.
