1990 Jeep cherokee took refrigerant. Works well when compressor engages. the compressor does no always get the 3 amps necessary for it to engage. Short circuiting to the battery it engages. What should I do?

Ever pulled all the relays and cleaned their terminals?

The low pressure switch on the side of the drier. Is it's connection good?
