So since the summer ended my MG ZS (2005 mk2) has leaked water in to the passenger footwell when it rains.

Did some investigation and found it was coming in through the interior fan. Bit confused, but on removing the fan could see water coming in through what looks like (while lying down in the foot well in the snap-your-spine-in-half-on-the-door-sill position) the underside of the windscreen scuttle panel.

Is this normal ZS behaviour?

I can't honestly see how this was ever designed to not either (a) leak or (b) rust; as form the under side it looks like the windscreen scuttle is just stuck over a bit of foam in some sort of hope the foam would soak up the water before it runs down into the interior. Anyone know if this is the case? I haven't actually removed the panel yet to look. That looks like more than a 10 minute job...



Also, my interior fan runs erratically. Mostly in that, it doesn't run. Hardly surprising since it's had rain water in it for the past few months. The fan feels a little more difficult to turn by hand than I'd expect, so I guess the internal rusting of the motor has knackered it!? It's odd because sometimes it runs fine and sounds like it's at full speed.

Again, this is presumably normal for a ZS? While I think of it, is a Mk1 interior fan the same as a Mk2? And is a Mk2 fan the same as Rover 45?

Ta!

Yes, all the fans are the same.

The solution to your problem is to seam seal the spot welded flange around the heater intake, you'll need to remove the plastic panel at the base of the windscreen to do this.

This happened to my car after the windscreen was replaced. The water would come down the windscreen, under the black panel that goes around the wipers, and drip straight down the spot welded air 'funnel'. I agree seal around the spot welded edge and also along the underside of the black plastic panel directly along the windscreen edge above the hole. I also replaced my fan with one from an older scrap civic which spun freely by comparison to the partially seized one that would squeel on start up. Also check that when you pour water into the area around the 'funnel' that it dissapears down the drain holes both sides of the car, as these can become blocked with debris over time,do this before you seal down the black panel!!
