Retrofit Heated Seats Factory look

Recommended Posts

For that rare fellow who would like to add factory heated seats. It can be done. First you must acquire the heated seats. My car is a 2007 GT3. I was able to, when a Rennlist member put his nearly new ones up for sale on that forum. He was replacing them with the GT2 seats in his 2010 GT3.

Next you need the HVAC Climate Control Unit. Part # 997 653 111 14 (Note the last digit can be 1,2,3,or 4. 4 was the most recent update.) These can be found used on ebay and other internet sites, as well as new from a dealer. I used Sunset Porsche.

I swapped out the seats and the control unit myself. Directions for those steps can be found on other posts. Planet 9 has a good article on PCM install that shows the Climate Control Unit removal.

The wiring harness for the heated seats connects exactly like my non heated seats did. The only problem: no wire was present to connect seat heaters to Climate Control Unit . My pals at Harper Porsche, the Knoxville dealership came through with the solution. A wire was ran directly from the Climate Control Unit to the seats, under the carpet of course. The final challenge was the wire connection. Jason, a Porsche Service Tech did a lot of research. This is the Gem of this Mod. Those connectors are a BMW part. Jason tracked them down and eventually acquired some. 30 cents each. Originally used in an older M3. (This has to be an abomination of some kind!) Hardwiring is an option but he was reluctant to go this way.

I picked up the car today. The outside temp was 38 degrees. The heated seats worked great! Toasty buns.
