fix = find leak, fix leak.
well that's not good considering i just re-charged it about 2 weeks ago and that was $100 for just 1/2 pound of r-12. I was getting a little frustrated last night and hit the buttons kinda hard on the ACC panel and actually got the AC to turn on, but then it shortly turned itself off after about 15 minutes. Looks like the panel is the initial culprit, but appears to have a leak as well. I'll definitely be going to a MB tech next week to have this looked at. Thank you everyone for all your help, your knowledge is priceless and extremely helpful.
