Looking for replacement seat heater element. My seat bottom sinks like a bowl. I have a little cushion I use. I don't see an element under there with seat out. Not much info around. Anyone have good suggestion for repair of the supports and heater element? Passenger side works great. Thanks. PS: Just finished b*tch job of sway bar bushing replacement and MAN what a difference in front end noise quieting. I had replaced shocks, ball joints, all arm bushes,drop links etc and still had clunks and bangs from worn out swaybar bushes! Much better now. Surprising what two rubber chunks can do!

 

The seat heating elements are wired in SERIES so you need to determine if one or both are open circuit (cushion or squab) or if the seat control module is faulty.

There are universal kits that can be fitted.
