SUBJECT:
Driver Side Power Mirror Vibrates While Driving

THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 23-39-97, DATED JUN 27, 1997, WHICH SHOULD BE REMOVED FROM YOUR FILES AND NOTED IN THE 1997 TECHNICAL SERVICE BULLETIN MANUAL (PUBLICATION NO. 81-699-98004). 1998 MODELS HAVE BEEN ADDED ALONG WITH A UNIQUE 1998 REPAIR PROCEDURE. ALL CHANGES ARE HIGHLIGHTED WITH **ASTERISKS**.

MODELS:
1994 - **1998** (BR/BE) Ram Trucks

SYMPTOM/CONDITION:

Driver side power mirror vibrates or blurred images in driver side mirror while driving.

DISCUSSION:








It has been identified that installation of aftermarket bugscreen deflectors can affect mirror vibration and other components. The Dodge Ram Truck is a highly developed aerodynamic design to minimize wind drag and noise, improved ride, and increased fuel economy. Current bugscreen deflectors are designed to disrupt the air flow in front of the vehicle to keep the windshield clear of bugs and debris (See Figures 1 and 2).

Depending on how this airflow is deflected, a number of potential undesirable side effects can occur, such as:

^ Mirror Vibration

^ Reduced Fuel Economy

^ Increased Wind Noise

^ Erratic Windshield Washer Spray

^ Excessive Antenna Movement

^ Booming Noise at Air Intake for Heater/Air Conditioning System

If the vehicle is equipped with a bugscreen deflector, perform Diagnosis One. If the vehicle is not equipped with a bugscreen deflector, perform Diagnosis Two.

DIAGNOSIS ONE:

1. Test drive the vehicle at freeway speeds to decide if the left (driver side) outside power rear view mirror vibrates or the images are blurred.

2. Remove Bugscreen Deflector.

3. Test drive the vehicle to determine that mirror vibration is gone. If vibration is still present, perform the following Repair Procedure. If the vibration is no longer present, the root cause of the vibration is the airflow turbulence caused from the bugscreen deflector.

NOTE:
INSTALLING BUGSCREEN DEFLECTORS MAY CAUSE MIRROR SHAKE THAT WILL NOT BE RESOLVED BY MIRROR REPLACEMENT OR INSTALLING THE MIRROR REINFORCEMENT BRACKET.

4. If it has been determined that the bugscreen is the root cause of the mirror vibration, the bugscreen should be removed. A Mopar bugscreen is available, p/n 82202559, that helps reduce air turbulence around the, power mirrors.

DIAGNOSIS TWO:

Test drive the vehicle at freeway speeds. If the, left (driver side) outside power rear view mirror vibrates or the images are blurred, perform the following Repair Procedure.
