HELP air-con drain pipe blocked

[Overdose]

I've been getting a mist through the vents and fogging up of the windscreen sometimes. I doubt its the heater core because I cant smell coolant and there isnt any coming through the footwells. theres only a musty dirty smell.

I've heard this is caused by a blocked drain pipe but no one has said where exactly it is.

I know it is around the gearbox but I had a look and cant see any pipes ending around there.

the car is a VT 5L manual if that changes anything.

also I was told that it can be blown out with a compressor but I'm not sure about that because it would come from inside the dash wouldnt it?

It doesn't stick out like a pipe really, more of a hole with a grommet. It's a bit hard to find so a torch will help. It's up above the transmission, more on the passenger's side I think. When you find it, shove something like a cable tie up there to dislogde any crap. Avoid using anything metal like a screwdriver unless you are careful. Be prepared for a shower if it is blocked.

drain pipe wasn't blocked, I have a picture if any one wants it.

I read in another thread that you can take the plenum off the left hand side near the windshield and take out some mesh and tap open a vent.
can someone please let me know exactly what to do?
I pulled off one layer of that black plasctic under the wipers and couldnt see anything worthwhile. do I have to take the next layer off?

There will be one on each side of the trans tunnel in your VR I think mate, there is in my VN and both were blocked.
I only found mine with the gearbox out completely and even then it took me a minute to work out what they were

Look for 2 clam lookin' black rubber things poking out of your floor pan. Big enough to stick your thumb in.
