Condition

Some customers may comment that a stop and/or tail lamp may not work correctly, or that the tail lamp has water in it.

Cause

This condition may be caused by the circuit board and/or gasket.

Correction

Remove the lamp assembly from the vehicle. Use the information below to diagnose and repair the lamp assembly.

If the base of the stop/tail lamp bulb is distorted, replace only the circuit board and gasket, as well as the bulb.
If the lamp leaks (has water in it, as opposed to condensation) but the reflective surfaces inside the lamp are not discolored, replace the circuit board and gasket.
Replace the lamp assembly only if the following condition(s) exist:

•	The lamp is discolored internally.

•	The lens is cracked.

•	A locking tab is broken.

•	The reflective surface is discolored.

After replacing the circuit board, ensure that all locking tabs are securely fastened to the circuit board.
