Hi all, I have no technical knowledge so please be gentle. Having done so very low level investigation, it would appear that the drivers side drainage duct(?) is blocked inside the sunroof. Would some blowing through a piece of pipe (say some plastic fish air filter piping help flush it through or do I need to take it to a mechanic type person?

Many thanks for your anticipated help and if you could keep any answers as low tech level as possible I would be very grateful as my usual level is to take it to my mechanic and say "you do it" but since buying my utterly beautiful but inordinately gas guzzling 4.2 rr sport supercharged I have decided to try and be more proactive!

I have had similar and yes of course any soft pipe is worth a go. If you hit a blockage then something stiffer may be needed such as copper wire etc.
I as soon as I felt something give ran water down the hole to wash it all through.

Unsure on sun roof but I wouldn't use any hard wire as some drains are made from soft materials and you may rip same.

Also once I managed to fire the hose straight into a hole and blew the blockage through but the back wash was messy so no good for a sun roof he he Many thanks
Paul

Have a look at this thread.

I did read that someone had a blockage which they tried to shift with wire - no luck - also forcing something down the pipe (wire / compressed air) may cause a joint to become disconnected (and thereby a bigger problem than when you started )

Th solution they ended up with was squirting wd40 down the line - left to soak then the blockage cleared with some water poured down Howard
