2008 MKZ Heated Seats fix

- Heated/cooled seats stopped working. After watching several videos I decided to put my own spin on it. Taking the seat out helped a LOT.
Tools: heat gun, soldering iron, wire crimps/snips, module, harness kit, zip ties.
The white part of the new wiring harness slides out the side of the clip to expose the tabs that allow you to release the wires,.. pull all the black wires out of the new clip and place factory wires in the new clip, .. I used both ground wires from the new clip and spliced those to the one ground wire. It saved tons of headache.
Do you have a video link? I wish I had seen that before I did it. Would have saved me time! If you have a link just reply with it! THANKS FOR THE TIP!
@@MrRobertFerrell I don't have a video it was something I did yesterday in about 10 mins.
I’m looking for the rewire video. Also my bolt on the rear left side is super tight.
I just did this on 2010 mkx but its not working with a new plug and module. I noticed the plug when i unplugged it only has 11 wires not 12. Is one missing? The lights turn on for about 5 seconds and then shut off
I would guess the module is different for different years. When I got my replacement, I compared it with the old unit to be sure everything matched.
Did you use any type of tool to get the plug out of the module? I know it’s burned in there but is there any trucks u learned? Double checking. Did you press the tab down and pull? Or is there a different way?
Nothing special, just stuck a flathead in there and twisted it a bit all around to break it loose. It was pretty glued in there with that melted part.
when unbolting the seat, did you have any concerns about the airbag in the seat possibly deploying by accident? I need to remove all the seats on a 2008 Lincoln MKZ and I’m thinking I need to be careful of that.
I wasn't concerned at all. If you're going to remove them (I just tipped the seat backwards) I would disconnect the battery and power the entire car down just to be safe. Check with your local tech to confirm!
i have a question. my heat seater is not working and we are going to attempt to fix it. i have 2008 mkx. the lights on the ip light up all 3 2 and 1 depending on how it is selected. they light up and stay on. my mechanic stated that he believed the lights would turn off once the sensor was alarmed to an issue. question did your ip selection stay lit or did it not come on or shut off?
thanks for the video.
A little bit of both. When it first started, they would light up, but nothing would happen. The seats worked intermittently at that point. Once it was totally fried, the lights would come on and then shut off after a short time.
In my case the lights did not come on and the seats would not heat or cool. At the time this problem occurred, there was a noticeable electrical burning smell.
All that for a heated seats thanks I'd rather just leave it alone
Hello and thank you so much for posting this video. The passenger seat works yet the drivers seat doesn't.
Really appreciate 🙏 and have a great weekend!
Thanks for the video. In my case I simply drilled out the burnt connector in the pigtail, ran a new wire (about 4 inches long ) through the hole with a copper connector on the pin. After reconnecting the pigtail, I soldered the new wire to the one where the contact clip burnt. This worked, showing that in my case the circuit board was still good. The only issue was the burnt connector. All seat heating and cooling functions are working again.
Brilliant! That's a much quicker fix for anyone willing to drill the burnt one.
Nice job with the fix Dr. Ferrell! -Glen F.
Thanks! I can't live without heated seats!
First of all, thanks for taking the trouble to video this, and upload it. That's a chore in itself. And, opening up the module is a big help. Could be wrong, but it looks like a total of four pins are connected to the same ground area of the PCB, no? Seems like it would be easy enough to splice them all together before they go into the plug. No need for new plug or module!
Do you have a part number for the wire harness? Im looking for one but dont want to order the wrong thing.
Pretty sure the one I used is a WPT928
Thank you very much sir! Headache saver!
what was the part # on your module and where did you get it
The number I used is the same one from the original module: 7L1T-14B663-BB. (6MXN91805) I got the replacement from an online reseller and the one I used came from a salvage. I kept the old one "just in case". I found it on Ebay. Worked perfectly and I use it every day now that it's cold outside!
Was this tutorial because BOTH seats were not working? I am experiencing a non-working heated/cooled seat on the driver side only.
I noticed it at first on the driver side, but ultimately both front seats failed.
If your module isn’t burnt it’s probably the heat pad in the seat which you can replace in less than 45 minutes without unbolting the seat.
If the light goes on for 10 secs, but no heating and the turns off that means the pads busted right?
For the module, did you need to have the dealer reprogram it for it to work, or was it just plug and play? Thanks for the video...
Just plug and play. When I plugged it in and turned on the car I had no idea if it would come on or not. Worked just fine first try.
How did you like your MKZ? 2.0 with a turbo right? What was the mpg?
Mine is a V6, normally aspirated non-turbo. I love it. I get about 28mpg average with 190K on the odometer.
Where did you order the part from?
The number I used is the same one from the original module: 7L1T-14B663-BB. (6MXN91805) I got the replacement from an online reseller and the one I used came from a salvage.
Another great video.
Would the new module make the cooled an heated seats work also
Yes. They both came on right away. Neither worked before I replaced the wiring harness. The old module still worked, too (so I kept it just in case...)
