I appreciate that response Larry, the two things I don't usually mess with are the inside of an auto trans and A/C. But, screw me once shame on you, screw me twice, shame on me. I spent 20 years in the service and if something was broken, I would fix it, but only when I fully understood what I was dealing with. At this point, I would be the fool to take it back to the MB dealer. It was a total lack of competence and responsibility on their part. Sorry if I sounded like I was on the defensive, but I can't stand it when someone tells me I can't do something.
