Moisture in Additional Turn Signal Lamp(s) in Rearview Mirrors

329

If you receive customer reports regarding moisture or water inside the additional turn signal lamp(s) (Figure 1), please advise the customer that

surfaces fog up whenever they are cold and come in contact with warmer, humid air. An example of this is the mirror in the bathroom which often

fogs up after showering because the warm humid air from the shower may condense on the colder surface of the mirror. The same occurs to the

additional turn signal lamps. Water vapor that is normally present within the lamp housing may condense on the colder surface in the surrounding

area which typically is the lens as the ambient temperature decreases. Any fogging will typically disappear after 1 or 2 hours during the day

depending on temperature and humidity. This condition is normal operation and does not call for repair. If there is any indication of greater moisture

in the housing, please check for external damage to the housing that may be the cause of the condition. Damage to other than production defect in the

housing is not covered by warranty.

Note:

For Model 204 vehicles, produced up to 08/2007 (up to VIN A064140 and F057431), there may be isolated cases of the turn signal lamp in the

outside mirror housing exhibiting a crack at the edge (weld seam), in these cases the turn signal lamp must be replaced must be replaced.
