Front Seat Heater Element Replacement for Buick Park Avenue 1999

Electrically operated heating coils may be incorporated directly into the seat cushion and the seatback covers.

Power to the coils is directed through a relay. The relay is mounted under the seat near the motor assemblies.

If diagnosis shows a non-functioning heater coil, replace the entire cover. Refer to Front Seat Back Cushion Cover and Cushion Pad Replacement or Front Seat Cushion Replacement .
