I am attempting to install a set of 2001 Suburban seats in my 72 SWB. Any help would be appreciated. They both have full power and heaters. The driver seat has 2 position memory. When I picked them up I got most of the harness. The guy at the yard cut a plug off at the drivers door for the driver seat memory and heater controller and cut another set of wires that headed from the console up under the dash and since the passanger door was missing I didn't get the harness for the heater out of it either. Has anyone installed a set of these? Any ideas on how to get the memory working? I have checked the wiring and have located the up/down, forward/back and the lumbar power supplies but can not see where the heater powers up from or the memory.

Thanks

I am not absolutley certain of this, but I strongly suspect the "memory" part of the seats is imbedded in the on-board computer. One of my vehicles is an 01 'burb with the options you describe. I lack a good wiring diagram, but I'll check the books I do have, and get back later. Meantime this goes to top, maybe somebody else can help.

Your going to have to sweet talk a tech at the dealer to give you a copy of the wiring diagrams or hope someone here has a set of Helms books for the truck (Chilton/Haynes wiring diagrams probably won't be specific enough). Like shadetree said ther is probably a BCM of some kind for the memory function. You can definately do this but will need good diagrams.

The BCM holds all of the memory and the resistance for the heater controls. You got to have that to use it.

Thank you for your input. I have a buddy that says he has a owner manual from a 01 burbon. He said there is a wiring diagram in the back of it. I have not seen it yet. I have traced the wires on my seats and it looks like there is a memory box located towards the front of the seat. At least that is where the same colored wires that are on the auto seat button go in. Of course the wires originate from a plug that used to go up under the dash somewhere. JOY JOY JOY! This is what I live for! I wish my wife had somebody else that could take care of that patio project she thought up. And you think that the seat heater will not work without the computer? That is just perfect. Looks like I'll be heading out to a U-Pull-It in the near future. Thanks again for you thoughts. If you have any more ideas that would be great.

HEY correction here! I just found out that the seat is not controlled by the BCM that was in 03 and beyond. I looked up the driver's seat heater and it says that it includes the module in the seat base. And you are also correct about the seat memory as well. They may even be the same module but I don't think so.

I had a 200 burb and traded it for an 04. I know there was a differance between them but I didn't know what that was other than the heater opperated a back heater as well as the butt heater. I picked up a seven circut block to hook up the seats. The seat harness has five hot leads going into it. Two 12 or 10 gage wires go to each seat. One of them of course runs the up/down, forward/back and the lumbar compressor the other one runs power to the black box under the driver seat but there isn't one under the pass seat. The 14 gage hot lead runs the center console light. I'm going to try and get the seats in and hooked up towards the end of next week. Thanks again for the input.

That will be really cool to have everything hooked up. Middle of the night, flip open the console and the light comes on while you warm your butt up in the winter. Awesome!

Imagine, a REMOTE start, and it sits, waiting and warming for you.

A remote start would be good, but then the dam thing would have to idle right. If I were to fix that my wife would want to drive it. Not good!

I'm going through something similar. I have seats out of a Range Rover though. Each seat had it's own computer. I finally gave up on the computer and made my own box full of relays. It takes 12 relays to drive each seat and that's without the butt heaters.

The computer controls the rear view mirrors and was looking for signals from the main computer in regards to vehicle speed, shift position etc. Looks like it was to lock out the memory while in motion. I'll be posting pictures of the box and seats when it's all done.

If I ever get enough time to get them in and finished I'll let you know how it came out and throw up some pics.
