well, first, make sure it's the control module that needs replacing. then find the part number to it. the #####-###-#### and then go to:
www.hparts.com
and type in that part number and that is about as good a deal as you can get on a brand new genuine replacement part.
remember, you'll need the #####-###-#### or else you'll have to try and write them an e-mail to describe the part and hope they know what you're talking about.
