Thread: Wet drivers floor not aircon

Check your plenum drain holes at each side. I have seen a few discos and ones I've owned where heavy rain builds up in the plenum tray, and rises enough to get to the level of the seal for the windscreen motor cover plate and the blank onj the passender side. The rubber seal can seperate alowing water in.
RTC around the opening can fix it. Other cause is a windscreen leak

Might be a silly question, but have you pulled up the carpet and made sure you don't have a rust hole in the floor? Mine did, and it's a common problem, apparently.

Check firewall near body mount brackets for cracks.

My passenger side carpet was getting wet and it was a rust hole

Definitely check this. Discos are known for it. I had a pair of cracks totaling about 80mm combined length from the passenger side. It was a pig of a job but I welded them up when the engine was out.

Certainly no rust in the floor. Will check for
Cracks in the fire wall

Do the D1s have the firewall plugs?
I only just put my passenger side one back in today and I was getting damp carpets in rain.

My D1 leaked through the windscreen seals. Didn't find out until the windscreen had to be replaced that they were perished and rain was running down the inside of the A pillar.
