Floor Board Getting Wet 900 1994

I have a 940. I noticed the other day that condensation from the air conditioner is running down onto the passenger floor board. What does this mean and how do you fix it? Is there a drain hole that could be plugged up? If so where is it?

Any response will be greatly appreciated. Thank you.

I had the identical problem with my 93 945 wagon 2 years ago. I reamed the small AC condensate drain grommet out with some wire/coat hanger. I then cleaned it and the area surrounding it thoroughly and applied a liberal amount of black silicone(windshield sealant) around the edge where it meets the firewall. Problem solved in about 4 minutes.

D.J.,

I had this same problem with my 944t very recently. The first thing I checked was the drain that extends out of the firewall in the engine compartment. I stuck a rigid electrical wire into it to make sure it wasn't clogged. It didn't help much and I was still getting water in the passenger footwell.

My next step was to remove the passenger side kickplate and the cover on the underside of the dash. After you remove these items you will see a black plenum cover (cover for the bottom of the airbox that houses the blower motor too) that has what appears to be a funnel that disappears into the firewall. At the junction where the plenum enters the firewall is a foam gasket into the firewall. I found my leak at this junction. If you run your car you may see a drip forming around this gasket. I sealed around the foam gasket with rtv silicone caulk. It took several tries until I got all of the leak. You'll know this worked when you notice alot more condensation water falling to the ground when you use your ac.

Anyway, no more wet carpet and potential rust. Give this a look if nothing else has worked yet.

I was at a Volvo specialist mechanic and he was showing me a 940 that had the same problem on the passenger side. I have a 960 and was asking him about the vacuum servo.

Any how, if you take the cover off the passenger side (you might to romove the glove box, don't know how but saw the guy doing it) and there is metallic pipe pointing downwards. Work around this. Check for leaks in the hoses, or for hoses the have fallen out of place.

I'm not the best at describing DIY work, but I hope this will help.

Okay, I will try and check out the drain lines. Thanks.

I'm thinking we've seen this on the board in the past. As I recall, the response seems to be that there is a drain tube from the evaporator under the dash that goes through the firewall to carry off any condensation that accumulates. Sometimes the hose can be plugged, but I think the more common cause is that the hose comes loose, or that the part that sticks through the firewall gets pushed back into the passenger compartment. Maybe somebody with direct knowledge can confirm this. Anyway, it's a place to start.

Good luck.

Just say a prayer that the heater radiator hasn't sprung a leak. If(when)that happens you're in for one of the toughest,time consuming or expensive repairs in the auto.
