Heated seats not working?

Hey BURDEDW,

There is a heated seat temperature module that may have gone out, here is a wiring diagram that will help you test the circuit to see whats going on. Test for power and ground and if it has them both then the module has gone out.

Run some tests and get back to us so we can continue helping you.

Best, Ken

This was a little above my pay grade so I took the car in and they said what you did and replaced the module car is all fixed! Thanks, I cant believe this site is free. God bless

I have the same issue only the lights stay on but heat and cold is not working on both passenger and driver seats... thought?

Yep, this is a classic module problem, but first did you check the fuses? Here is a guide and the fuse locations so you can check it out and get back to us:

test with the key on. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.

I'm having the same issue, with the climate control front seats both turning on for a few seconds and turning off. I'm looking at the diagrams and charts that have been shared but I'm not sure where or what I should be checking. Like what fuse to check I guess would be the start, or how a single module effects both hot and cold and both from seats. rear seats work fine though.

Thank you

Hi Tyler,

Is your vehicle the same year, make, and model? I need to know that to make sure I'm looking at the right schematics. Oftentimes, they use circuit breakers on these rather than a traditional fuse. If something is drawing too much power, it will kick the breaker and then work again later.

Let me know.

I hadn't heard of that, but yes it is the same year make and model. 2007 Lincoln mkx.

Hi,

This is powered via a traditional fuse. If you look below, I've attached a few pics. The first two are the entire wiring schematic for the heated seats. I circled two fuses in pic 1 that are related. I need you to check them. In addition to checking the fuse condition, make sure there is power to and from them.

Here is a link you may find helpful:

If you look at pics 3 and 4, they show fuse locations in the boxes. Pic 3 is the box under the hood and 4 is under the dash on the driver's side.

Let me know what you find.

Take care,
Joe

I have the same vehicle, and I am only having the issue on the driver's seat. The passenger seat works fine. Could it be the heating element in the seat being bad causing my issue? I have changed out the module under the passenger seat with no change. Any suggestions would be greatly appreciated.

Yes, to test to see if it is the heating element test the yel/blu wire for power when the system is on at the seat heating element.

This guide can help:

If it is getting power check the ground wire as well by switching the test light lead to power and test the blk/blu wire. Let me know what you find.
