I had heatd seat problem but haven't replaced heat pad - my problem was fairly common from what I understand. Same problem on my '93 and '94. The wire connector to the heated pad can easiily be pulled loose. Wires are relativily small and as I recall consist of a red and a white that attach about in the middle under the seat. Hard to get to but better then taking seat apart. I used standard neddle nosed pilers to reach into the small opening to firmly plug in connection. Check for loose wres first!

Note - at first I asked dealer about this and after they 'looked' at it, they wanted to replace pad and thermostat control unit for only a small, three figure fee. Very glad I decided to look at myself first!
