97 chassis and engine stuff will be the same, but wiring will be a little different.

look for a '95/96.

it's not rocket science, but time consuming to pull the seat and peel the leather back enough to remove & fix the heater
my mechanic gave me a tool & hog ties (the clips that hold the leather), but i found i could open the existing ones & reuse, but tie-raps would have worked too

there are 2 3-pin connectors in the back of the seat, with an ohm meter you can determine which heater element is open

Isn't this incorrect? I read on a different thread if one goes out it takes the other with it.

I'm having the same problem as eles with my drivers seat, takes very long to heat up and when it does, I'm sure it's not reaching optimum heat. I searched and couldn't find anything about taking long to heat up and low temp, I only found explanations of the back cushion and bottom cushion being wired together resulting in one dead element taking out the other.
