Problem with driver side heated seat
Hi All,
The drivers seat heat on my 2010 F-150 stopped working. The passengers side works fine. When I press the button on the dash, it lights for 2-3 seconds, then goes out. I'm a new user to this forum, but have been looking around all weekend for a fix. I found many posts, but they are older and the equipment I'm seeing on my 2010 F-150 looks different. I found the wires coming from the heating pad. I was going to try and test for continuity but the wires have a plastic fitting and I can't get contact to the wires. I found a diagram on Foreparts.com showing that the heated seat control module is part # 14C724. I was able to locate on the passengers side, but not on the drivers side so I wasn't able to swap and see if that was the problem.
Any advice, diagrams or pictures would be greatly appreciated. Its getting pretty cold here in Washington!
Thanks in advance!

I've got the same issue with my 09 Lariat. Press the button for the drivers side heated seat, light comes on for no more than a second or two, then shuts off. Passenger side works just fine, which is great for the wife, but doesn't do me a bit of good. I was wondering if you had found the root cause or the solution to the problem. Like you mentioned in your post above, I've seen threads for older vehicles with a similar problem, but nothing to speak of for later models like 09-10. The one thread I did see that offered anything close to a solution involved taking it to the dealer for them to fix it.
I too would appreciate any input.

Assuming your trucks are heated seats and not climate controlled seats with AC.
Likely that your grids are shot. Disconnect connector C364. This is a small, 4-pin connector underneath your seat toward the front edge of the bottom cushion. Pin 1, yellow-blue trace (??? pretty sure) supplies power.
The cushion and backrest heaters are wired in series. Voltage flows in via yellow-blue and goes through the cushion heater first. It exits on pin 4 grey-violet. At this point it should have ~7 volts since the back cushion will drop the rest of the voltage.
If you have battery voltage on pin 1 and ...
- no voltage on pin 4 then you have an open in the lower grid
- battery voltage on pin 4 then you have an open in the backrest grid OR a bad ground
(the odds of a broken wire connecting the two grids together within the seat are very slim)
