hi guys.i got what i thought was a great deal on a pair of sport seats from a 2000 corvette ragtop recently.i want to mount them in my 71 chevelle and have hit a snag.the passenger seat's power functions work fine but the driver's are not.after some testing it turns out that the relay box under the bottom cushion is not working.my question is:does anybody know if any other GM vehicle uses the same box?at about $250.each,i figured if other cars(or trucks)used the same relay box it would easy to pick one up in the salvage yard.
drivers side corvette seats MAY have a memory for different drivers..i read up about it a few years back.. i can find out.. fairly easily do you have a part number on the controller box????if there is a VIN number on the seats.. you can actually enter that vin number in one of the GM parts stores online and it will direct you to the original parts.. i am taking that your drivers seat track looks like this..you might want to manually test the motors.. there is one supplier out there that actually rebuilds these because of something failing.. seat motors are usually available from GM or thru AC delco.. and are also usually easily rebuilt.. sometimes.. a careful cleaning of excessive grease off the brushes and commutator is all that is needed..
hi wayne.i have already tested all the motors in both seats directly and with swapping the boxes back and forth.both seats work fine with the passenger box and nothing with the driver's box.the part # on the driver's box is:10435193.i have no interest in the memory functions,i just want the basic motor adjustments to work with the factory switches on the seats.which they do with the passenger side box.
hmm.. that seems to be a module with memory and also controls the tilt and telescopic column and is connected to the computer network in the car..SEAT ASM/FRONT (AQ9) - YSEAT ASM/FRONT (AR9) - Y 10342158 MODULE,D/SEAT CONT(WHEN REPL 10435193 W/10342158, DETERMINE IF FRT S/D MODULE IS 10342159. IF SO, DO NOT ALSO REPL 10342159) Y(AAB,AQ9,AR9)are your seat controls you have swapped ..on the side of the seat??? #6these are bigger than you can see.. open them in a new window or drag to your desktop..are you in los angeles???
nope.i live in winnipeg,manitoba canada.i didn't swap the switches on the side of the seats because when i swapped the relay boxes from seat to seat,the switches on both seats worked fine.it seems to be in the driver's relay box.
how about finding another right seat relay box???. those might be easier to find.. if it will connect up..i have not messes with the seats in these.. open the diagrams in a new window.. you will see that they are connected to the computer system. there seem to be a run on these.. as they seem to be sold out at GM.. can you open it and check carefully for broken solder joints preventing operation.. i have had to open so many electronic boxes to repair them its crazy.. you MUST use extreme care to wear a static strap to prevent static build up that will blow the electronics up.. what.. most computer data electronics burn out at about 18 volts.. the sparks from your fingers when moving around can be 20,000 volts.. think of being zapped when walking across a carpet.. touching a door knob.. and ZAP.. you won't even feel 20 volts that burns out the tiny circuit devices on the board.. some will blow out at 8 to 10 volts.
thanks for all your help wayne.i think i'll try to find a right seat relay box for that seat like you suggested.in the meantime i have a friend who is an electronics engineer who is willing to have a look at this one.maybe we'll get lucky and he'll find an easy solution.crossing fingers,toes etc.
take a picture of the seat electrical connector.. visit the junk yards.. dig into the various caddy buick and olds editions.. you might find a right hand seat box that will work.. best of luck.. and i wish i could have helped more.. i just don't have enough hands on with that circuit to help you much..
the photo idea is great!i'll do that and prowl the yards for a match.thanks again.
