I have been reading, and reading on this forum but am more confused. I have a 93' 500SEL (143K miles) Last year AC was fine. This year nothing. My reliable Indy said the compressor was locked up. I had them replace the compressor and drier. It blew cold for 3 weeks. I did not use it for a week, and now it blows hot. It didn't even get progressively hot. I don't think my compressor comes on, nor do the aux. fans. There seems to be some greasy liquid on the new drier. (Possible leak?) I am taking it back in for a pressure test. My question is, is there other things I can have them check, just in case they are clueless on the switches and sensors on this car. This car is rare in these parts, and I am loosing confidence in them. I know of the Evap. woes. If the pressure is OK now what? If it isn't then what? Diagnostics on the controller were:
1. 23
2. 94
3. 87
4. 87
5. 88
6. 14
7. 3
8. 10
9. 30
Can someone check these out and interpret?

This forum is awesome.
Thanks
