SUBJECT:
Intermittent Momentary Loss Of Power Assist
THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 19-01-97, DATED JAN. 24, 1997, WHICH SHOULD BE REMOVED FROM YOUR FILES AND NOTED IN THE 1996 SERVICE BULLETIN MANUAL (PUBLICATION NO. 81-699-97010). ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE INSTALLATION OF A NEW SERPENTINE DRIVE BELT AND ADDING 1998 TO MODELS.
MODELS:
1996 - **1998** (NS) Town & Country/Caravan/Voyager
1996 - **1998** (GS) Chrysler Voyager (International Market)
NOTE:
THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A 3.3L OR 3.8L ENGINE.
SYMPTOM/CONDITION:
During high humidity climate conditions, some vehicles may experience a momentary loss of power assist for the steering when turning corners with the A/C or defroster "ON" or recently "ON".
DIAGNOSIS:
1. Inspect the HVAC housing condensate drain tube to determine if a spout has been installed and is in the 4 o'clock position as viewed from the front of the vehicle (refer to illustration). If a spout is not present, perform Repair Procedure A. If the spout is present but not properly positioned, reposition the spout to the 4 o'clock position.
2. With the engine turned "OFF", check the position of the black pointer on the back side of the serpentine belt tensioner in relation to the tensioner casting. This position is the pointer's "home position".
3. Place a 15 mm wrench on the tensioner pulley bolt and apply force to rotate the tensioner clockwise. The tensioner should rotate smoothly and freely with no binding as the tensioner is rotated and released.
4. When the tensioner pulley is released, the black pointer should return to its "home position". Any Binding or resistance to rotation of the tensioner should result in the black pointer not returning to its "home position". If the black pointer does not return to its "home position", the tensioner is not supplying adequate tension to the belt, perform Repair Procedure B.
