Title: How to check your sunroof drains aren't blocked by Cavalier 342

Over time, bits of leaves, and general crud can block up the sunroof drains leaving moisture and damp inside the cabin and steamed up windows as well as corrosion where you can't see it. Particularly if the sunroof has been left tilted up for long periods. It's worth at least once annually to check if the drains are clear and water flows through clearly. For those who haven't done it before and would like to give it a shot it's as easy as this:

Slide open the sunroof fully.

Pour water (bit of washing up liquid optional) in the drain channel ( yellow arrows) on both sides of the sunroof.

Image

If the drains are clear, the water should drop out of drain holes near the front jacking points on both sides.

Image

And on both rear corners.
If the drains are well clear, it should just pour straight out like this:

While you've got the sunroof open, if it's a bit sticky when sliding, pour some drip oil or general grease on the runners (Green arrows).

If the rear drains aren't letting water through, pull the corners of the boot carpet out, you'll see the rubber hose feeding down right in the corner of the boot. Pull it out, clear out any muck and clear any muck in the hole in the bodywork where the hose goes through. It will have little stubby flaps in it, bit fiddly but once cleared it should be fine. Don't forget to firmly push the drain hose back in to prevent any boot leaks. Hope this helps. :)
