HelloCustomerand welcome to justanswer.com,
$120 must be their diagnostic rate that they charge. Unfortunately most times it is the unit that is the faulty component.
If have some one or you want to try and replace the unit yourself it isn't really that difficult to replace.
you can find units on e-bay for a lot less than the dealer is trying to charge you for a replacement unit
yes, I believe the unit is the problem. Sometimes there are wiring issues, but from the symptoms you describe, I would have to guess the unit is faulty..
I can send you a link to the instructions on replacing the unit .
here is the link you need
