200clc JD air conditioner problem

My 200clc ac quit working freon is ok and cools fine with hot jumper wire on compressor. Fan and controls seem ok but no voltage to compressor wire. Switch on receiver dryer ok. Does not work with jumper in switch wire. Wondering if current to compressor is controlled by a relay or if climate control box could be bad not sending voltage to compressor
