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


It has been determined that 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, and provide improved ride, and increased fuel economy. Current bugscreens are designed to interrupt the airflow and disturb it to keep the windshield and vehicle clear of bugs and debris (See Fig 1 and Fig 2).

A number of potential undesirable side effects can occur, such as:

If equipped with a bugscreen deflector, perform diagnosis 1, and if not equipped, perform diagnosis 2.

Diagnosis One:

1. Test drive at freeway speeds to determine if the drivers outside power mirror vibrates or the images are blurred.

2. Remove the bugscreen deflector

3. Test drive again to observe if the vibration is gone. If 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.


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 part number 82202559, that helps reduce the air turbulence around power mirrors.

Diagnosis Two:

Test drive the vehicle at freeway speeds. If the left, driver side power mirror still vibrates, perform the following repair procedure.
