I think there was mention of a drain that seems to clog up. Couldn't hurt to rub a little silicone spray on the seals either. Knock on Wood, it's rainy here in SoCal and no leaks so far.

since you have a black car i will venture a guess that your rear drip panel inside the sunroof enclosure is broken.
(Now is also a good time to swap out the old seals for fresh on the sunroof) Only solution is to remove the sunroof , then remove the broken tray then install a new part, also inspect the drains use a piece of weed wacker line to clear the lines not compressed air

You can get to front drain holes without removing the sun roof. I can'r recall about the back ones.

Where is it getting wet? May not be the sun roof at all. If the passenger floor board is wet it could be the blower box seal. If it is dripping at the aft edge of the headliner it could be the hatch seal.
A common Problem with the drivers side front drain is having the drain tube crushed when the factory installed the vacuum reservoir. This was the case with my 85. Have to remove the wheel well liner, then vac reservoir and trim the crushed end off the tube to fix it. Easy enough to do though. |
