Heated Seat problem....turn on....turns itself back off...

Dad's '04 D-max has developed a problem with the driver's side seat heater. He can turn the back on by itself and it works just fine. But when he turns the back and bottom button on high, it kicks off in about 2-3 seconds. If he turns it on Medium setting, it takes it about 5-6 seconds, and it he turns it on low it stays on about 10-15 seconds. Bottom line, it kicks itself off and will not stay on long enough to amount to any heat.

Again, this is only with the button that controls the bottom and back. Back button alone works just fine.

Any thoughts, knowledge or help as to what is going on and what I need to do to fix it? Parts that are needed, repair process, etc...??

Thanks.

My driver seat in my 04' does goofy stuff too. My heater works fine but the forward/backward button decided to switch around on me and operate backwards now. It wont travel on the runners as far as before either. Now when i push the button forward my seat goes back and when i push it back the seat goes forward. Sometimes the lower back adjuster wont work either but most of the time it will.

Im thinking its time for a new seat.

seat heater

My 04 drivers side seat heater won't work & will shut off the passengers side when activated. I'm still trying to figure it out. I also need help.

Chad the element in the bottom is shorting out somewhere and causing it to pull to much juice and shutting itself off.

Has anyone been able to fix this with just cleaning the connectors/relays? I'd like to not take the seat apart to replace the element. I don't really need them, but they would be nice.

Humm... I will let Dad know that piece of info. He happens to have an Electronics Engineering degree and is pretty savy when it comes to figuring out electrical problems. Guess he was just too lazy to take the time to go in and figure it out himself.

Thanks. If anybody else comes up with a DYI fix for it...please let me know.
