98 ML 320 A/C problem

Replaced leaking condencer to conpressor line. Evacuated system and added 2 cans of 134a. static pressure reading is 70 lbs.

Problem: the compressor will not operate - clutch doesn't engage; cooling fans don't turn on.

checked fuses and relay - all appear to be in good order.

Can the A/C switch in the dash be a problem - how do you check it ?

Any help is appreciated!
