Another A/C Problem on a W124 300TE
I'm hoping against the worst case scenario here. My 1991 300TE 4matic has 255 k miles on it and I converted to R134a last summer. Everything was good for the summer then.
Two weeks ago, my wife tells me the air isn't working. First time she's checked this summer. I added some R134a on a cool Saturday morning, charging to 175 psig head pressure, which was around 2 1/4 times ambient at the time. The car ran cold for a few days, now it's back to no a/c. Worse yet, the clutch is turning and I'm not getting any cooling!!
I'm going to check pressures this weekend, but I don't know any way to get the clutch to turn with no cooling effect other than a blown compressor. Any other ideas out there???
Please let me know. Thanks.
