There are usually a combination of 4 nut/bolts per seat. You'll need a T55 or T50 torque bit and an 18mm deep socket to remove these. To access them slide the seat to the extreme front and rear. Once all nuts/bolts are removed tilt seat back and undo wiring harness from underneath. You have to remove both driver and front passenger seat to remove the centre console /middle seat.

Look in the fuse box on the driver's side of the vehicle on the outboard side of the dash under the triangular cover which snaps off and on. This panel is not visible when the door is closed. If you have your owner's manual, look on page 5-104. This is where the fuses and relay/circuit breaker descriptions, layout, and specifications begin. This section runs to page 5-111.
You are going to check fuse number IGN3, a red plastic, stab-in miniature 10Amp fuse. It has an "S"-shaped element visible through the side of the fuse body. If the element is broken or burned, replace this fuse. DO NOT use a replacement fuse of ANY other rating; use an identical 10Amp fuse ONLY.
You are also going to look for the "Center Instrument Panel Fuse Block," located under the instrument panel, to the left of the steering column. You are going to check the device labeled "30A CB Seat." This is driver and passenger seat module circuit breaker. This circuit breaker is an automatic resetting device, replacement is necessary only if there is no other problem, and it will not reset.
If only the driver seat is affect, the problem is not the CB Seat; check the wire harness and connector under the seat. There is almost no clearance under the seat, and it may needs be removed to check this. There are four 14mm or 15mm bolts, one at each outboard corner of the seat, the front ones under snap-on plastic covers, which anchor the seat to the vehicle. These bolts are installed with an anti-seize anchoring compound which make them difficult to remove, but aside from elbow grease, there is no other trick to removing them.
Good luck, and if I have helped you, please remember to comment/vote.
