INOPERATIVE SIX-WAY POWER SEAT - 1982-1983 DEVILLES AND ELDORADOS (EXCEPT BIARRITZ) EQUIPPED WITH MEMORY SEAT


An inoperative memory six-way power seat system on the subject vehicles can be caused by a low voltage condition at the module. If the module sees a voltage lower than 10.5 volts, it will become inoperative.

A second faulty condition may also exist. When operating in the manual mode, seat motion will stop, even though switch is still depressed and end of travel is not reached. Reactuating switch will cause seat to begin moving again.

AH manufacturing and field stock is being modified at this time. An modules (P/N 20310105) with a date code of 2340, or lower, are of the first type and require modification. This code (2 = year 82, 340 = 340th day of year) is stamped in white ink on the module.

In the event that this condition occurs and a module is not available, the six-way seat can be operated without the memory seat feature by disconnecting the module and reconnecting the wiring without the module in place.
