Condition

Cause
The signal unit adhesive may not be fully seated to the back side of the glass.
Correction
Replace the upper mirror glass only with a new mirror kit, P/N 15933017-LH or 15933018-RH. It is not necessary to replace the entire mirror assembly. The mirror kit contains the electric upper mirror glass and a molded wedge tool (instructions embossed on tool).
Use the following procedure to replace the upper mirror glass:
Tape the entire mirror glass in order to prevent personal injury.
Tilt the upper glass down.
Tilt the lower glass down.
Using the tool provided with the kit at the bottom of the upper mirror, pry the upper glass toward the top of the housing until the glass backing plate disconnects from the housing.
Disconnect the electrical connector.
Properly dispose of the old glass assembly.
Attach the electrical connector to the new glass assembly.
Align the spring fingers of the new upper glass assembly to the ramps at the sides and bottom of the housing.
Position the glass assembly at the top of the housing opening and slide down to engage the locking tabs.
