I just purchased a well driven 2002 CLK 430 coupe. One of the issues is no A/C. Tried to do a little digging before posting a bunch of questions. Here is what I have.

The EC light is on.

I drove the car for about 20 minutes and then went through the diagnostic mode while still running and wrote the numbers down.

1 94
2 134
3 152
4 96
5 82
6 190
7 3
8 94
9 0
10 0.8
20 0
21 6
22 0
23 0
24 14.2
40 8
41 5
42 200
43 14

Error Codes-

B1227
B1241
B1416

I realize that the compressor is not engaged. Is the #7 value too low? If that is the case, can I just put the gauges on an add freon? Will something need to be done to over ride the EC light and get the compressor to pump? Are there any other issues with my numbers?

Any suggestion where should I start?
Thanks, Chad

For what it is worth, I replaced the compressor, expansion valve and dryer. The compressor was shot.

$300 later, not counting beer, The car now makes ice cream.
