need solution

Does anyone know a solution for this problem? I'm having the same problem with my 1997 Jeep Cherokee. Front Passinger side is wet. I have drilled a hole in the duck and tried to blow air in with my air compressor. I've also tried to stick in a wire about 4 ft long to try and clear any blockage. Nothing has worked - still have the water in the blower box leaking to floor.

Seems I should be able to drill a hole in frame rail that it supposely drains into. Would anyone know anymore about this problem?

Thanks

It is due to a clogged drain, but alot of people have a hard time getting it fixed, and usually the dealer wants an arm and a leg to fix it.

The following is from another forum and may be worth a try:

Regarding A/C Condensation-

I just went through this with my 1997 Grand Cherokee. The first thing I looked for was the condensate drain line. I could not find it and, at my wife's suggestion, took it to our local mechanic. He was not able to find it either and suggested I take it to the dealer. (Not at $80.00/Hour!!)

I decided to try to look again. I found what appeared to be the drain on the inside of the vehicle. It's located under the dash on the passenger side. The problem is that it is part of the whole Condenser/Fan/Vent assembly and it spans the whole passenger side. The drain drops down from this assembly in a "V" shape to a round (about 2.5" Dia.) piece that goes through the firewall. (This will make more sense when you see it.) The other side is not visible because it is behind a boxed portion of the body.

At this point I realized that removing the whole unit was going to be a huge task that I was not ready to do. Also, this would probably not be the last time I had to do this.

Solution-

I decided to drill a 3/8" hole in the middle of the round piece that fits through the firewall. (Have a towel that you don't mind getting dirty ready). I then used a coat hanger to clean out as much of the leaves and other black gunk that had accumulated as possible. Running the A/C while you do this can help, but it will also make more water.

Once I felt I had most of the garbage cleaned out. I blew compressed air into the hole. I then let the area dry out. I used a 3/8" NPT Pipe plug ($1.00 at the local hardware store) and some black silicone sealant to plug the hole.

I've spent the past week with a wonderfully dry interior despite the high temps and humidity we've been having. Even better, if and when this happens again, I now can easily access the drain.

Hope this Helps!

Thanks much okc,
I actually had already seen that one, I think I'm going to try some form of re-routing a new drain on this jeep.
By the way, I'm in MWC, work at tinker.

Is that the DISA building or the Radome testing building?

Small world we live in. I just separated from the Air Force in July and now a government contractor (program analyst) for the C135 PDM office.
