Customer Question

Water on the rf floorboard, looking for the flapper or condensate drain, but have not found what looks like the conventional hose. It's a 91 Sedan Deville, 4.9.
JA: Are you fixing your DeVille yourself? What have you tried so far?
Customer: Car sat under a tree, removed carpet and interior, cleaned and removed plastic / screened cover under hood, on top of cowl. Suspect the heater suitcase is plugged, need to figure out what the drain looks like please.
JA: Have you checked the coolant level? Has there been any leaking from the hoses?
Customer: No, coolant system is fine, nothing missing there. It is just/ was just water.
JA: Anything else you want the mechanic to know before I connect you?
Customer: no, I am confident it needs drained, ie the heater housing drain is plugged

Hi, my name is ***** ***** drain for the heater housing is accessed from under the car, on the passenger side firewall, where the large aluminum a/c lines goes thru the firewall, about 8 inches under neath these lines, you will see a hose sticking out about an inch, the diameter is about 5/8 of an inch, you need to run a coat hanger or stiff wire into this line, when it unplgs, it will drain the water out quickly, so be careful,Tim

I have been under the car several times, and it is currently on a 2 post hoist. Do not see or feel the tube as you describe. I'm not a new car guy, 58 years old, worked on cars since 16 years old. i took a picture, confirming you are talking about a front wheel drive, 4.9 V8 Cadillac Sedan Deville? Can you send a picture to show this tube?Just resent the picture via text
