1997 Deville ac compressor locked out - low refrigerant charge message. Reads 70 psi static. Does it need a charge? How do you start compressor to add refrigerant?
70 psi static does need a charge.find compressor relay, jump relay and compressor will start. add refrigerant,replace relay and a/c should work fine
With the engine off hook up the can 134 take + battery cable and remove frm battery. Wait 60 seconds (now would be a good time to attach can to low side) After the 60 secs replace the cable to battery and start can set acto auto very quickly!!!!! The compressor will run before car code loads to setting allowing the 134 to enter the system before low 134 is displayed the auto light will stay on and the comp.is running. Charged to proper psi and turn off the can then remove the hose from the charging nipple. blkcadideville
