While I was doing something unrelated to this problem I had reason to remove my O/S/R wheel arch liner which gave good access the roof motor location drain holes.
This is the O/S one, but the N/S one is located in the same area on the other side.

If you squeeze the rubber end of the drain and it's dry you most likely won't have water in the side wells above, but always worth rodding it out with a piece of stiff wire, just make sure it has a very blunt end to stop any damage to the pipe. As I had my compressor charged I gave t a gentle blow and could hear air freely escaping above so I'm sure that side is free, although I believe the motor is located on the N/S of the car so I will check that one tomorrow.
You don't have to remove the whole arch liner to get to the drains, you can remove the front lower portion by removing 1 x 10mm plastic nut and 3 x 8mm self tapping bolts, one of which is underneath the sill area.

There is a lug on the bottom of this panels which has to locate in the piece attached to the car when you replace the panel.

I did this a while back Tony, the rubber bungs just pull out of the metal tube so you can give them a good clean. if you don't have an airline you can poor a little water in the join between the roof and the body birectly behind the door shut, the water will drain through.

If you are inherently lazy (like me for example) you can get to the drains by feel alone without the need to remove any trim panels. I reached up into the cavity behind the rear wheel on each side and pulled the rubber bit off then cleaned it out with this:

Refit rubber thingies, jobs a gooden'.
That's where I've been going wrong. I played trumpet and cornet for many years and never did any of my instruments see anything like that. If only I had I would be set up now :confused:
