95 E420 - A/C compressor won't engage and aux fans never start. Bypassed temp and pressure switches and had mechanic check freon. Have read tons of posts but so far striking out. Compressor and fans turn freely by hand. All switches on ACC panel work, defrost and heat work. What relays and sensors could prevent both compressor and aux fans from engaging? I just bought the car so don't have any repair manuals (yet). Just rebuilt my power steering this past weekend (ugh) so ready to get this A/C fixed! Any help is greatly appreciated. Great forum, glad to be in such good company! Thanks,

Terry
