w201 A/C help please

[Bolognablake]

Hi guys, I just bought a w201 a few weeks ago. I had the A/C recovered and I pulled vacuum on it today for a little over an hour, and it held vacuum for 30 minutes no problem.

I filled with r12 (two 18oz cans, pretty close to 2.2lbs, I'm tired and the math eludes me). It was about 88* and I was at ~35psi Low and 250ish High but the aux fans weren't on. I was only getting about 15* reduction from ambient temp at the center vents, 20* max at 55mph.

What am I missing? Even without the aux fans, it should be more efficient at idle. Also, the high side seem high, but again I'm not sure if that's due to the aux fans not working. It doesn't seem high enough for TXV issues, but I'm not an expert.

Any ideas?

Thanks guys!
