Right side heated seat not heating-The light on the button comes on but seat stays cold-left side works ok??? help! wires look like they are pluged in. The seats never have heated a lot, they did not stay...
You seem to have 2 issues.
The first where the seat does not seem to heat, with the light staying on, I would think this to be a broken wire in the heating mat. The F-150 seat bottom is usually where this happens, right where the thigh would be on the seat.
To test, on the heated seat module under the seat, the Yellow w/ Light Blue stripe wire goes to the seat bottom then to the Gray w/ Light Blue stripe wire to the seat back and then back to the Violet w/ Light Blue stripe wire to the heated seat module ( the bottom and back are in series ).
Unplug the connector, and with a meter set to resistance or ohms, 1st check the Yellow w/ Light Blue stripe wire to the Violet w/ light blue stripe wire. You should read a high resistance ( if it is a scale, you need to use the 1K or 10K ohm or scale range ). You should get a very high resistance. If you read an open, there is a broken wire some where. 2nd check the Yellow w/ Light Blue stripe wire to the Gray w/ Light Blue stripe wire. If you have an open on the seat bottom and seat back, chances are this will also show an open.
If it reads as an open, you need to replace the heated seat mat that is open. When you take the seat cover off, it will be obvious where the problem is at. You can also consider a new seat bottom at the same time, if you are going to the trouble of removing the seat cover.
The seat not getting very hot could be a break down in the element or the temperature sensor ( also in the seat bottom ). The cure for this is to replace the seat bottom heated seat mat. IF it is the temp probe, this will have an impact on the seat bottom and back temperatures.
Over time I have noticed that the seats work a little less every year. Hard to tell until you get a new element for them how bad it is. The elements are MSRP $ 60.00, Ford dealer selling parts online : ~ 40.00 + S/H. The cushion is ~ MSRP 120.00 online price ~ 80.00.
The cushion is not required, as long as you are careful removing the old element. I usually replace the cushion if I am going to the trouble to remove the seat cover, specifically on the driver's side. With a new seat cushion, the truck will feel new again .
