    Heated/Cooled seat problem

    Remote started my car yesterday morning but and when I got it the seats were still cold. The heated seat lights were on. On my way to work I turned my heated seat on and it never got warm. On my way home I turned the passenger side on and it to never got warm. I've read a few threads on the connector under the passenger seat getting hot and melting. I put the seat all the way back and all the way up. I could easily see the connection. I disconnected it and looked at both connectors. There is no signs that the connector itself has ever gotten hot. There is no discoloration of the plastics or any of the wires. When the cooling option is selected the fan does not come on. I can hear a single click under the passenger seat when I turn the heated seat on. After a second or so I hear another click. I have checked the fuse and it "appears" to be good. I haven't replaced it. So I am thinking that maybe the module is toast? Is there anything obvious I'm missing? As always, thanks guys.

    Check the fuse that powers the module. I just did mine, the connector was not really burnt much at all, but enough to not make good contact and keep the heaters/coolers from working.

    Re: Heated/Cooled seat problem

    Thanks for the reply bigtone. While at lunch I checked fuses F27 and F47. One was a 30a and one was a 10a. Those are the only two fuses that are referenced for the heated/cool seats in the owners manual. Is there another fuse I should check? I'll remove the passenger seat to have a good look at the wires on my next day off. I will post my findings. It may help others in the future.

    Re: Heated/Cooled seat problem

    I had a 2001 Buick Park Avenue that had a similar problem (with the heated seat issue ... the seat never heated up and there was a clicking sound periodically when the heated seat was turned on). I was told that a common problem with the Park Ave heated seats is the heating elements themselves breaking ... and on that car, the heating elements are sewn into the underside of the leather (necessitating replacing at the very least the leather seating surfaces, if not the whole seat). I never tried to fix it because the seats were too expensive to replace.

    I'm not sure if this is a similar problem with the DTS seats, but because of this, I use my DTS heated seats and steering wheel functions very sparingly and I don't leave them on for long when I do use them.

    DTS seats are a different animal. No elements. Those are the fuses. Mine was burnt right at the female connector. I did the job without removing the seat.

    Re: Heated/Cooled seat problem

    you sure you checked the right connector? It's not easy to see or get to but you can with the seat all the way up in front and all the way forward. It plugs straight up in to the module that is attached to the bottom of the passenger seat. When I first got my DTS last year, I devised a work- around where I folded a small staple and placed it inside the module end of the connector and that helped for 6 mos. or so until the connector finally melted into a blob. Just got the car back from the Cadillac dealer where they replaced the connector for 277 bucks all in. I didn't need the module; that would have made it more like $850!

    Re: Heated/Cooled seat problem

    Right you are. I was looking at the wrong connector. I located the correct one and one pin is burnt and the surround plastic is melted. The module itself looks to be ok. So I am guessing I can get another connector at the local Caddy dealership. Is there a method to removing the wires from the existing connector or is just "beat it til its in pieces" and the pull the wires free? I feel better now that I know what the problem is. Thanks!!

    I know there is a better way to remove the wires, but I really like the idea of "beat it till it's in pieces"...
    I get that way sometimes and that actually made me laugh...

    Re: Heated/Cooled seat problem

    I have my passenger seat removed from the car. I went to the dealership this morning and got p/n 15326110. I tried to get a few of the metal pins p/n 15304711. None of the dealerships in my area have any listing for p/n 15304711. I thought maybe I would get lucky and not need any but I was wrong. The cable was very close to being burned in two where the plastic had melted. My car is in the garage and I do not want to put it back together without this being done. Does anybody have a working GM p/n for the little pins? When I search google it comes up as a delco p/n. The dealership could not find p/n 15326110 when looking at my car. Jim, I didn't have to beat it to pieces and fish the wires from the wreckage. But for anybody else doing this, there is a grey locking mechanism running through the connector. It will not come out easily because the plastic is melted. I used a pair of wire cutters to chisel my way through the melted part and then used a pair of needle nose pliers to pull the grey piece out. There are black retaining clips left holding each wire in. I used a very small flat head screw driver to move the black clip away from the wire and then pulled each wire out. It was frustrating until it was easy Now I just need one little clip to have my seats working again.

    Did you try Chevrolet, Buick and GMC? They all use the connector.
    G M send trays of connectors every year and they usually are keep in the parts department.
    Ask them if they could sell you some out of one of the trays and order some to replace them. You may get lucky.

    Re: Heated/Cooled seat problem

    What I learned today, at least in my area, is that the parts department has no idea that these exist. If there isn't a p/n in the system then they can not help you. My advise for those looking at their local dealership for these is to ask one of the mechanics. They will know what you are talking and they might even give you one or two for free. Thank you Mr. GM Mechanic for giving me a few for free. And thank you community for helping me resolve this problem.

    Replacing it only temporarily fixes it. I did mine, worked like new for 2 weeks and melted AGAIN!!! About to do some "american engineering" of my own!
