How upsetting that must be, I hope you gave them holly he**. They should refund your money for that part that did not need to be replaced, yeah right, huh. Well good luck I hope the PCM is the problem, I think when my husband gets home from traveling we will take it somewhere for the PCM, that probably isn't a do it yourself job. Too bad, we paid cash for our D a little over 2 months ago and since we have spent money on it like we have car payment... Please let us know what happens next, Good Luck to you.
