Thank you everyone for the feedback - all of it!!
I'm looking over everything. I just finished filter & oil changes...also put in new front brake pads and cleaned the banjo bolt related to the ALDA. I had some soot build-up...probably from Winter start-ups (replaced the glow plugs after about 2-3 wks of that.)
....now FINALLY, I can get back to the A/C and your input. Ben, I can definitely understand why you cut the belt.
Mach4, thank you for letting me know that the pulley spinning does NOT mean the compressor isn't seized.
I was also thinking that if the PO didn't replace the belt, that there probably IS a problem. You know I'm hoping for the best.
I will be back with some feedback/questions in a day or two.
Thanks again everyone!!
