Heated Seat Problem

The Heated Seat Lite comes on when i push the button, but no heat to the seats...It switches form hi to low but still no seat heat. Any ideas on what to check, Thanks in advance for any help.

Do you hear a "click" when you hit the button"?

I HAVE THE SAME PROBLEMO THE PASSENGER SIDE WORKS BUT THE DRIVERS SIDE DOSENT!!! ITS NOT FAIR LOL

1) please check the fuses and breakers. You may probably find an open fuse or hot thermal breaker.

2) check the wiring under the seat. If the breaker was hot or fuse was blown you will find a wire chafed and shorted onto another wire or the frame of the car. If the fuses were OK you will probably have to remove the seat to find a broken connection in the vicinity of the heating elements, or a broken wire at some point that flexes a lot (look at it carefully).

Seat heaters are simple systems and don't readily break. Matter of fact a sneaky way to put heated seats in whatever car is to get them out of a "donor" car that has relatively simple (or identical) upholstery - you have to surf the pick-and-pull to find such a "donor" - and install them on a new 20 or 30 A switched fused circuit in your car. Removing and reinstalling the upholstery in your car can be a chore - if you're in a cold area, a chore you'll smile about some cold day...

THANKS I REALLY APPRECIATE IT!

Yes i do...

Can anyone tell me the exact physical location of the driver's side heated seat thermistor? In other words, is it located in the upper or lower half of the seat? I have tried to isolate the infamous problem of the Heated Seat switch lighting normally, the heat control module relay "clicking" on-off every 15 seconds, but no heat from the seat. I believe it to likely be the internal seat thermistor. I would like to try and get access to thermistor as directly as possible without removing the seat and all of the upholstery if possible.

I would greatly appreciate any guidance from perhaps someone who has been underneath the seat cover and observed the inner-workings of the heated seat element and thermistor.

Thanks!

There is really no way to get at the seat thermistor without removing the seat and then removing the leather. You use a Dremel Moto-Tool or wire cutters to cut the hog rings, you use a set of hog ring pliers and hog rings to reattach. Some NAPA stores have there; they are always available from Aubuchon Hardware, on line, also from JCWhitney. And other places.

You are more likely to find a connection broken, I think, than a bum thermistor. IRIC you can get a replacement thermistor through Radio Shack, however if you can still read the code on the thermistor a better bet is Digi-Key (www.digikey.com). I buy parts from both.

Thanks for the feedback and info on where to procure parts. I need to check the external wiring more thoroughly before getting into seat removal/disassembly, and then, if necessary, weigh-out how important this fix is to me. Like most of us, it really bugs me when something is not working properly on my RIv, not to mention the simple pleasures of a "bun-warmer" on these brisk mornings, even in Atlanta!

Buried on this site somewhere is a pictorial write up of removing the seat covers. It's not that big a deal, although definitely time-consuming.

I did more troubleshooting this weekend and found nothing externally. I also watched a couple YouTube vids on removing seat covers and repairing the heating elements...so I am about ready to take this on when I have a couple days off.

Thanks Albert, for the tips. I will search this site and see if I can find the info on cover removal.

Maybe AA will chime in, I can't find the thread. He's great at finding old threads.
