    Not your typical Heated Seats not working, please read! Passenger seat no power!!

    I have read all of the threads about seat heaters not working, looking at the module that is attached to the seat and the issues with the pins and what not. This is a bit different. Please read on........


    First of all my seat heaters work, when my passenger seat has power....
    When the passenger seat doesn't have power, both the seat heaters/coolers do not work (on either side)
    I have checked every fuse on the driver side dash, under the hood and the circuit breakers by the drivers foot area. Everything that is supposed to have power does, and the fuses/breakers are all fine.

    I first noticed this last week, and made a different thread but now that more research has gone into it, I am very lost.

    I have included pictures of the module and the harness, if anyone has a wiring diagram on where/how power gets up to the seat/module that would be helpful...

    Pics of the harness that plugs into the module


    pics of the module pins



    I am 100% positive that the motor is NOT seized in the passenger seat, that it is a power delivery issue somewhere. Weird it just happened out of nowhere...

    Anyone know what pins should have power/ground in that first pic? I can start pinning and checking for power/ground to pinpoint where the problem is.

    Thanks so much for any help!

    Hard to believe but you were totally right.

    This was the loose connector




    Thanks! I was thinking something totally different (BCM or something)!!!

    You were lucky, usually when the connector gets loose it shorts and burns the connectors out.

    Hey guys,
    I have the same problem on my 09 Escalade.
    I just checked all those conectors. When I disconnect the last one behind the passenger seat and plug it right back, I do hear a click and then 2 times a short sound like a fan. But thats it. If I turn the seat heater out, there is no click, like on the passenger side, no more. No warm seat.
    Please helm me !!

    You were right on! I've had trouble with seat not moving and with the cold weather I noticed the heated seats not working. Reconnected plug and started working! Thanks for the pics, knew exactly which one to replug.

    Lars, if you look at big Robs first pic more than likely that connector under the passenger's seat is burning out pull the connector and take a look. I have been dealing with this problem for 7 years lol. also try replacing the fuse under the hood just in case good luck
