No.

I guess I cant link to the actual part that way.

Sounds about right. There are resistance specs on all the switches if you can find them. Thats generally stuff only the dealers have.

So this is what I need?

yup

Ill have to get one then. Its over $200 new.

I picked one of these up from a junkyard today and just installed it. Hopefully the problem is fixed.

If not I just wasted $40.
