A/C Drain Hose Q. Hi, I have a 1995 Jeep Grand Cherokee Laredo 4X4 with a 318 V-8. The A/C Condenses on to the passenger side floor board. I think the hose is plugged up, but I can't find the hose so I can run a wire or something inside it to unplug it. Do you know where I can find it. Thanks, Daylon

A. Jeep had a problem with this and issued a TSB on it. This should fix you right up.

AC Evaporator Drain Blockage

NO: 24-06-96
GROUP: Heating & A/C
DATE: June 28, 1996

SUBJECT:
A/C Evaporator Drain Blockage

MODELS:
1993 - 1996 (ZJ) Grand Cherokee/Grand Wagoneer
1993 - 1996 (ZG) Grand Cherokee (overseas markets)

SYMPTOM/CONDITION:
Debris may collect in the evaporator drain tube area causing blockage of the tube. This can lead to water leaking from the heater housing, water sloshing around in the housing and odor from decayed organic debris. This bulletin provides instructions to gain easy access to the drain tube for clearing foreign matter from the tube, without removal of the heater A/C housing.

DIAGNOSIS:
Operate the system in the A/C mode and verify that water is draining from the system. The water drains into the frame rail and exits in the center of the vehicle. If no water is draining, the system is blocked and requires cleaning.

PARTS REQUIRED:
1     5255217     Plug

REPAIR PROCEDURE:
This bulletin involves drilling a hole in the A/C evaporator housing to allow for cleaning of the drain tube.

1. Pull the carpet down in the passengers foot well and locate the evaporator drain in the housing (See Illustration).

2. Drill a 1/4 inch hole in the center of the drain tube housing as shown. Clear the drain tube with a wire or suitable tool by inserting it through the hole and into the drain tube.

3. Insert plug, P/N 5255217 into the 1/4 inch hole drilled previously.

4. Verify that the drain is clear by operating the system in the A/C mode and observing that water is draining.
