Was at the yard this morning and had the rear leather seat out of a trep in all of 5min, feeling good started on the fronts and doh, they are in the back position and are powered seats... And the battery has literally been cut out of the car.
Whats the easiest way to get power? Im guessing hook a booster pack to the battery cables, though they are cut and could be difficult. Can you plug a booster into the cigeret lighter and get power that way? Also do you need the key to move the seat?
Just want to be prepaured this time... ;) Oh also are the back bolts smaller than the front 2? Tried getting at them and the open end 5/8 wrench slipped (5 /8 socket worked on front bolts) .
All 4 bolts should be the same. The seats will power without the key. What many people have done is use cordless drill batteries to power them, if you have access to a power pack that's better. Bring some wire and your power source with you. Look for a green two wire connector under the seat, cut it on the BODY side, strip the wires and power the seat up. Take the front bolts out first if you can get them without moving the seat, then move and get to the rears.
Take the cover off of the PDC (fuse box under the hood, in front of the coolant overflow).
Connect your positive booster cable to the stud with the incoming red wire.
Connect your negative to some ground on the body.
If all the fuses are still there, you should have power at the seats.
Connecting at the PDC is just a shortcut. That red wire goes back to the positive jump post.
Well I took your advice and foun a set of 300m seats! Same color as the trep ones I had found, actually I took the back seat from the trep and the fronts from the 300m... is that stupid? Can't tell a difference in color out of the car anyway, the trep rear doesn't have the little "holes" the 300's do but I like that better so the kids unavoidable spills don't go through...
Had the opposite problem on this car, seats all the way forward. Ended up going with paintballdude05's suggestion, brought a little 18v drill battery and wired it into the power connector on the seat motors, worked like a charm (and made me feel like MacGyver for a moment there).
You may notice only 1 front... 5 minutes to go in the yard, on the LAST bolt, thinking finally get these damn seats and the damn bolt just spins in the hole! Had to leave it for tomorrow will bring a pry bar to put some pressure on the bracket. Nothings easy! Now to hit up some heated seat wiring howto's.
I would of went with the full M seat conversion, but I can see your reasoning behind going the way you did. To get that last bolt out you would probably need a cutting tool to cut the head of the bolt. I had this happen on a friends '99 M and it was a bitch. Once you do have it out though grab the entire wiring harness from the passenger side on over to the drivers. Make sure to cut enough wire out of the body harness and not from the seat harness.
Man, Im done with the yards for a while :( bolt came out pretty easy actually with some pressure from behind... Went to get the harness and suprise lost my side cutters and screwdriver. Did a major hack job with a dull knife I found. Couldnt remove the console so had to cut the damn harness in half anyway.
Oh well will be easier to solder it back together than start from scratch in the car.
