Sunroof leak

My 1988 3.2 has a slight leak from the sunroof into the roof linings at the rear sides. The drain tubes are clear and water floods out through them into the channels next to the engine, when poured into the sides of the open sunroof. So the drain channels are good. But despite this, a little comes into the car with the result that the heat insulation under the back seats gets damp. I presume there is a short metal tube at the back of the sunroof space with this plastic pipe attached:

And I presume it's the junction of the plastic and metal pipes at the back corners of the sunroof which is not watertight. Anyone got any experience water-tightening this junction- in terms of how to access, is it easy, does roof linig need removing etc.?

Thanks. I had a scan. I doubt the 996 and 997 ones have much in common with an 88 3.2 but maybe the 993 does. I couldn't see any details re the junction between the body snf the hose.

I should never have read this post because I thought, blimey, I've never checked these drain holes and I think I really ought to. So took the car out the garage, hit the sunroof switch - nothing, no sunroof. No no, the car does have a sunroof, it's just not working. I had a quick look, popped out the clock and speedo and was confronted by a right old mess of bodged up wiring plus the switch itself feels as if it has seen better days. I'm going to re - do the wiring and if I have no success obviously I shall have to delve deeper. Ugh, just hate 911 wiring.

Start the engine and get some revs up, then try. Mine moves better when the voltage is a touch higher!
Also, there's a clutch in the motor which can slip.
