Apparently I lost the function of all driver's seat buttons, except lumbar support, at or near the same moment as the SRS malfunction notice, "Driver's Restraint System Malfunction," displayed on the instrument cluster. I need some guidance. Fuse 68 has tested good.

1. How do I remove the seat button panel without damaging its fasteners?

2. How do I gain enough access under the seat to check for a loose connection?

3. Do I risk setting off the side airbags by working at the side or under the seat?

4. Any idea how the two malfunctions are related? It was a rainy day, but copious water didn't enter the seat area.


Thanks for input.
