Power Seat 900

Dear tedv,

Hope you're well. You'll need offset metric box-end (ring) wrenches, to access the bolts. The color-matched plastic bolt covers may need to be sacrificed, if you can't lift them out of the way. You should then be able to back-out the bolts. This will take some time, given limited access.

Please read the following:
DEATH DANGER WARNING: Before trying to remove the seat, remove the negative battery cable clamp from the battery terminal, and put the clamp in a plastic bag, to isolate it. This cuts power supply to the SRS (Airbag) System. The airbag sensor is under the driver's seat, affixed to the floor pan. If this sensor is banged if you drop the seat on it, or drop a tool on it the airbag could deploy. This can be lethal, at close quarters. It will also be costly: a new sensor is about $1,200. A new airbag is about the same.

The relays are in the seat computer, a black plastic box attached to the underside of the seat. If the seat doesn't move at all, it is likely that the computer's main relay has failed. The relays are not separately available: the computer must be replaced. You should be able to get one from a salvage yard.

The seat computer is not sealed: the halves of the case can be separated, by using a small, flat-blade screwdriver to separated the tabs, that hold together the two halves.

You should see one larger relay, and - if I recall correctly - six smaller relays.

Using a portable 12-volt source, you should attach the positive to the contact leading to the heavy red or red-black wire (in the gray connector, at the front of the seat rail, closest to the door). The power source's negative should be connected to the black wire, at the same gray connector.

Hope this helps. In the meantime, Happy Holidays!!!

Yours faithfully,

Spook
