Symptom:

Lost all power to drivers seat only. No forward/reverse, tilt or bolster/lumbar. The passenger side works normally.

First things I checked, obvisously fuse, but alas I have looked in the manual and online, couldn't find location. I did come across a couple of circuit breakers, one under hood and one inside cab, both checked out ok. I then moved my attention to the underside of the drivers seat, what a nightmare. All visable wires looked connected and unscathed.

Under Dash Circuit Breakers:

I then decided to look at the Power Seat Module itself, once removed from the lower seat cushion, I found its a sealed unit. I decided to swap out with the passenger to see if the module itself failed. The working passenger side Power Seat Module did not work on the drivers side. I replaced both back to their proper places.

Moving along, I went to the ole stand by, Google. There were many sites that recommended going to a dealer and having the module updated with new software, umm at the time I did not consider this an option. One site had mentioned to pull the 30 AMP circuit breaker for 30 seconds to reset the modules, that did not work. I continued on, many, many pages into Google, I found a site that someone posted "chaffed wires" at main power connection. Ah ha, so I contorted myself between the rear seat and drivers seat where I found the Main Power Cover, I removed it to find the power wires (no chaffed wires), I wiggled the two harnesses, and tried to move seat, BINGO loose wires at the main connection. I used small zip ties to secure the connectors together.

I want to say thanks also, my seat hasn't worked for about a year now and it wasn't so bad for me cause it was stuck in my spot, however, the bad part was that the heated seat didn't work. Took me about 5 min to get it working again, that includes the time it took to read the post! Thanks

Hello friends, I have a 2006 Escalade and the forward/backward on the drivers front seat stopped working but everything else still works which includes tilt, bolster/lumbar/heated seats.
I'm thinking maybe just the forward/backward motor burned up? please help thank you.

Pull the harness for the motor and carefully apply 12 volts to the terminals (there is two plugs one for the motor and one for the position sensor)
Either way the whole seat track has to be replaced

^check the connections at the driver's seat module(under the front of the driver's seat)

Also check the wiring for any chafing or damaged spots

If the connections and wiring check out then you may have to replace the seat module(as the pedal controls work through it)

Okay great. I will check thanks. Crazy thing is that took it to local dealer and they told me i needed some computer module to fix this. Quote of 2000. I hladly declined.

that is highway robbery

I have priced the seat module and it's nowhere near that(even with labor)

I would go somewhere else

It's possible you can get one at a junk yard or salvage yard for a LOT less as it doesn't really need to be programmed to the truck as long as the doner truck has the same features(a Yukon Denali module will work)

Do you if its possible to buy a new harness. My dad looked at it and I believe the dealer cut some wires and did something to the harness under the passenger seat

godsdiablo
10-24-15, 05:13 PM
Is it possible to solder the wires together? I'm sure you can go to a junk yard and get the harness cheap or head over to the dealership and get a price on the harness I'm sure they sell that

the cadillac man
10-25-15, 12:58 AM
Yes you can buy the harness but sheesh it's outrageous on the price(I know I already priced it back of this)

I would solder the wiring back together and see if everything works afterwards as the other poster has mentioned(DON'T forget to heat shrink the work to prevent any short circuits)

godsdiablo
10-25-15, 08:24 AM
If you double heat shrink then solder and then electrical tape them you won't need a harness it'll last a lifetime

Sorry to be a pest. But when u say seat module. Is it the driver seat memory module? Or something else. Just trying to locate the correct part online to order.

It's located under the front of the driver's seat

I have done 3 of these. The power in the molex plug under the seat burns up and all I do is patch the wire around the molex with a but fitting. Did mine last year and my sister in laws 4 years ago no more issues. look for a burnt wire into the molex will be black and crusty.

----------

also the dealership said it would be about 2500 to fix and replace modules. Should have let them do it after I video my fix and put it back

----------

Last picture he posted look at wiring correctly on molex plug. If one is burnt up clip on both ends where it goes in and out and route it without using molex plug and crimp with butt connection... Done 2 like this

Thanks for the tip. In my vehicle nothing was "black and crusty", as shown in "his" last picture.

Hmm, I am kinda at a loss here. I would have loved to "video" my fix and charge $25.00 or $2,500.00 as you stated for my free fix that I had taken the time to document and post here. Gee I wish I would have charged something at over 16,300 "looksies" at this thread. Even at $25.00 for my free fix, my math comes up to $400k.....Dummy me.

Thanks for the respect "he". I post here daily to contribute to this forum. I take it as a bit of disrespect/insult being refereed to as "he", I guess its my upbringing.

But again thank you for making somewhat of sense in your first post. Welcome to the forum. Enjoy the board and remember to have your camera handy when you post your DIY's in the future.
