Default 93 Sc400 Ac Error Codes

CAN ANYONE TELL ME WHAT THESE AC ERROR CODES MEAN ON MY 93 SC400? ERROR CODE 21- SOLAR SENSOR, 22-DETECT COMPRESSOR LOCK. ANY HELP OR LOCATION OF THE SOLAR SENSOR WOULD BE GREAT.

A/C Error Code 22, Could be any of the following;

Slack/loose belt
Compressor Lock Sensor or circuit failure
A/C ECU failure

The diagnostic routine is on my site under Electrical\Air-Con. Take it to a dealer, it's very complex.

London Bill, I've looked all over your site and can't find anything on Compressor lock Sensor. Also can't find the Electrical\Air-Con heading. Considering it is now 5 years later - is this diagnostic routine still on your site?
