How to get inside seat switches[700/190] posted by Philip on
Sunday, 6 February 2000, at 12:02 p.m.
The seat adjustment switches on my 760 do not work unless I push on the bottom of the circuit board. When I do this, I hear a click (like a relay connecting) and then they all work. I will re-solder the connections on the bottom of the board, but I can't figure out how to get the board out of the plastic case, so I can get at the other side. Does anyone know how to get the board out of the plastic cover?
Thanks.
Philip

Gee. I just spent 5 hours on Sat. doing just that!. Remove the cover over the rear seatback gear unit and then thak out the phillips head screw at the rear of the plastic "pod" that holds the switch assembly. There is also a similar screw at the front of the "pod" that is not easy to get at but a good offset screwdriver should do the job. Both of these screws go into the seat frame. On the bottom of the "pod" there are 2 bolts that hold the switch assembly in place. Remove these and you and pull the switch assembly up -- this should give you limited access to the PC board. You can them resolder to your heart's content. If this doesn't give you enough room then remove the seat (4 bolts - push to rear and lift) and you can then cut some of the cable ties under the seat to loosen things up. NB -- The switch assembly is a single unit with multiple solder points to the PC board -- if you need to repair a switch GENTLY pry up on the switch actuator and you will have access to the interior of the switch. All the PC board wiring is on the bottom of the board -- My major problem has been the on/off "STOP" switch -- it is easily bypassed by soldering a short wire between the 2 board connections toward the rear of the stop switch section of the board. Note that there are 2 relays on the board and you can't get at them if they are defective but you can prolly bypass them if you are daring! :-)
