w140 aircon woe!!!

[rupert e]

hey guys ,Need your professional advice, the w140 92 300 se im working on goes like this., the ac blower motor suddenly dropped dead, i jumped the terminals of the blower motor and it worked so naturally i thought that the resistor was the problem, however i noticed that the compressor is not engaging is this also related to the resistor?? is there a relay that controls the compressor that might be the cause? (klima?) thanks man i would really aprreciate it., oh the refrigerant charge is normal no leaks i checked.
all the fuses are ok
