So I have a 3dr Mk4 4Motion golf with a sunroof which in the 18 months of ownership I have found various small leaks. My rear window used to fog up alot because the drain from the sunroof on the divers side wasnt connected properly in the boot for some reason, the pipe was not pushed in to the rubber grommet! So then I still kept finding the car smelling a bit pond like recently, to discovery the passenger side rear footwell had water in it!
The sunroof is just fine, I've checked all the drains and from what I can tell they are doing their job, but it seems that water is actually coming in through the door, which is a bit of a mystery!
What the water seems to be doing is finding its way in to the rear footwell via the door seal, but when you open the door the water is getting in to the seal where it meets the plastic and the water seems to drip off of the actual underside of the door. So today I have had the door in pieces because the microswitch which does the interior light/alarm on that side had stopped working properly ages ago and I figured they could be linked, inside of the door was kind of dry, except the back of the speaker was a little damp too (eg the plastic surround, not the actual cone) and the other end where it had been dripping out.
I'm at a bit of a loss, any pointers on where they commonly leak from on the doors?
Also if its possible to get a replacement plastic bit for the winder mechanism as the motor mounting points have all broken as usual. Also as no doubt I'll have this to bits again, is there any does and donts with replacement door locks?
I was looking on ebay and they arent too expensive, makes sense to just replace it if I have the door in bits again to continue finding this leak.
