I finished replacing the seat heater elements on my driver seat over the weekend and wanted to post a bit of the process to replace them. It took me less than 3 hours, including a break for dinner. In my post under the topic Heated seats not working, page 14 I posted about my troubleshooting using PIT543A (Diagnostic Tips – Front Heated Seats). In brief, I went through the troubleshooting steps and identified the problem as both of my heating elements that were impeding with too much resistance to function. I have a 2014 Crew Cab SLT with Heated and Cooled seats and the safety seat vibrator. The part numbers I ordered were 23170194 and 23223775. They were perfect replacements, and I could also tell that there were some minor updates I could see from my originals. Hopefully GM has fixed the garbage heaters that were installed originally and this time they’ll last a lot longer. The heating pads have the cooling layer built-in to allow the seat venting to blow through the seat. The heating element is covered by a felt material that sits right against the leather. Under that is the layer for the ventilation material, which feels a lot like bubble wrap and allows the air to flow out through nickel sized holes spaced around the heating pad layer. So contrary to some reports from dealers trying to explain poor performance, the heating element is directly against the leather… the venting layer is thus under the heating layer. On to the actual work. The first step to the repair was removing the seat. Take the headrest off, it'll be easier to if you just get it out of the way right away. Removing the rigid seat back is easy, and you can follow PI1091 for more info on that. There are only 2 T50 bolts holding the seat in place. Remove the plastic trim covering the seat tracks, and move the seat forward enough to get access to the bolts at the rear of the tracks. With the trim removed, you can break the bolts loose and remove them. I read this next tip online, but disconnect the negative battery lead before removing the big yellow and grey wire connector that you can now see with the trim removed. That way you avoid potentially, yet unlikely, causing an air bag light to come on in your dash that your dealer would have to reset. Slide the red safety tab back on the connector, then rotate the grey latch to disengage the connector. This is the only connector going between the seat itself and the vehicle body. At this point I took off all the seat trim I could get to. The trim piece with the power seat controls has a hidden philips screw that is on the lower front of the seat that you have to get to from behind the trim. Otherwise, all the other trim has visible screws. Next, remove the seat belt anchor (another T50 bolt). You'll have to take off another piece of seat trim covering the pretensioner assembly, and disconnect a wire that runs to the seat belt pretensioner trigger. The pretensioner wire comes off by first prying up on the red safety tab, and then it just lifts straight off.

So I have a 05 CCSB Z71 with cloth seats and no seat heaters. I live in Alaska and seat heaters are much appreciated up here. I've done a bit of research and it seems like more hassle than it's worth to try to use the stock heater controls mounted on the door because I won't have the necessary wiring without the LT seats (is that right?). Anyways, I've been looking at universal kits and it seems like they're poorly suited to the seat design with the velcro down the middle and such. My question is whether I could pay the extra money for the GM heater pads but use a generic switch and relay setup. Would that work?

Hey Guys, I didn't do a full write up, but wanted to compile all the links I used in one place to maybe help others. My driver side seat heater went out last year or so, and my bottom foam was absolutely shot. Even had a lean toward the door, wife and I both noticed it causing us pain on the way to Florida, so I finally stopped putting it off. Decided if I was going to do the seat heater, I was going to do the TSBs on the under side as well as the foam itself. I went back and forth on doing the OEM foam, but finally settled on attempting to upgrade it. Went with The Seat Shop option on Amazon. Very quality piece, fit like OEM, has the same connections for the tubes on the leather cover and the velcro on the bottom side leather attaches to in 2 spots. The stiffness is noticeable feeling them side by side. I feel this one will hold up better, but time will tell. Ill circle back in a year or so and report back. Parts: The Seat Shop Durofoam I bought, part number may vary slightly check for your application. Heated vs Cooled etc. https://www.amazon.com/gp/product/B078NG3V47/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I bought my seat heater from the local dealer. After looking around and adding shipping the difference was negligible. I ended up with part number GM 23168136. Yours may vary depending on year, model, heated, cooled, etc. TSB parts ACDelco 10-4057 Synthetic Multi-Purpose Glycol Lubricant GM 13594989 Shim Clip GM 13405675 RETAINER-F/SEAT CUSH LATL ADJR Process: Links I used to aid in tear down and replacement below.
