mikes04ss Posted January 17, 2007 Author Report Share Posted January 17, 2007 (edited) There's a seat memory module under the driver's seat. I believe this controls the seat heater. #15101509. Then there's another module/sensor that sends current to the passenger heater. #88938614. <{POST_SNAPBACK}> Thanks CoolBlueSS!!

This under-seat module also controls all of the seat position motors, and driver profile seat memory positions. It also manages input signals from the switches on the side of the seat.

misterp Posted January 17, 2007 Report Share Posted January 17, 2007 According to my warranty ticket module #15101509 got replaced; in addition to seat heater problems it also fixed a seat position memory issue. Mr. P. Quote Link to comment Share on other sites More sharing options...

Mr. P. <{POST_SNAPBACK}> Interesting ... *scratches chin* I am hoping that all they did to fix was not just reprogram it, and charge you for a whole new module ... I found this on their site ...

As far as I can tell, memory and heated seats go hand in hand. Quote Link to comment Share on other sites More sharing options...
misterp Posted January 17, 2007 Report Share Posted January 17, 2007 I am hoping that all they did to fix was not just reprogram it, and charge you for a whole new module ...I know that they did, I had to wait 3 days for it to come from Arlington. But the software issues with seat position recall is a long-standing problem, they've been trying to get that right for years now. Even when functioning corretly the seats 'creep' and on early trucks have been known to go psyco and move all the way forwards & upwards. Mr. P.

CoolBlueSS Posted January 17, 2007 Report Share Posted January 17, 2007 I had mine set for memory seat to active with the remote, and I finally turned that off. It got to where every few days the seat would be way out of whack, and I'd have to spend the 15 minutes getting it back where I wanted it. OCD.

mikes04ss Posted January 18, 2007 Author Report Share Posted January 18, 2007 (edited) So this module controls both driver and passenger seats? Because it's happening to both. Edited January 18, 2007 by mikes04ss (see edit history) Quote Link to comment Share on other sites More sharing options...

SilveradoEsEs Posted January 18, 2007 Report Share Posted January 18, 2007 A couple of weeks ago, my heated seats were cycling on and off randomly. I didn't even turn it on when I got in the truck. I just noticed all of a sudden, my ass and back started getting warm. When I looked over at the buttons on the door, they were cycling through all of the settings repetitively. After several restarts that day, the problem continued. The next day, the problem went away?!? Quote Link to comment Share on other sites More sharing options...

Sounds more like a sticky button ... of maybe you got some liquid in behind the door switches and they were shorting until they dried out ...

Because it's happening to both.I had the same problem in both seats and replacing the #15101509 module fixed everything. Mr. P. did anyone experience a kind of smell when the seat was acting up ? would that just be the module or the element or both ? Quote Link to comment Share on other sites More sharing options...
EmergencyVP1 Posted January 19, 2007 Report Share Posted January 19, 2007 My '03 had a similar problem 3 weeks ago. Heated seats would not come on, push the button, would light for a few seconds then shut off. Then the horn quit working. Then the seats would self adjust. Turns out it was the drivers side under seat wiring harness. 2 days in the shop and it works fine now....Jason Quote Link to comment Share on other sites More sharing options...
