This is a relatively common problem. The drain hose takes a rather indirect route to get to a place where it can actually drain. Debris from the cowl vent gets into the exchanger and turns to compost. This dirt gets pulled into the drain hose by the condensation from the evaporator and eventually plugs up the hose. The condensation either overflows the exchanger or it causes condensation to form on the outside of the exchanger, which drips onto the carpeting. There are a couple of things you can do. You can try hooking a shop vac to the drain hose and try to pull the gunk out. You should be able to see the hose peeking out near the frame at the rear of the right front wheel well. This is a temporary fix at best, as it only gets what is blocking the hose. There is more stuff in there. A better choice is to line the passenger footwell with lots (and I mean LOTS) of towels, remove the blower motor from the exchanger, and use a garden hose in short bursts of spray to try and rinse out the accumulated mess. I also run the shop vac while doing this, to help draw the water out. The best fix is to dismantle the whole mess and give it a good cleaning. This is hard to do as not all of the fasteners are easily accessible without dismantling a lot of what is under the dash. -- Mike -------------- Original message from "Christopher W.
