Hi, My cruise control stopped working. I have been reading some of the other posting and hearing about doing a self testing. Right now I don't get anything including no light on the dash. Can someone tell me more about the self testing and how it's preformed? I went to my local For dealer, they told me they don't want to touch it but if I give a $100 deposit I can borrow something called a Fastco Speed Control Fast Checker. Do I need this to do the self test? Thanks in advanced for any help on this matter.
