10speed

My econ button wouldnt shut off when the temp outside warmed up. Last night it was cold here in Mich. 20 deg.and the econ button would shut off and the ac would blow cold. I figured it needed a refridge.charge so this afternoon i ran the car and the econ button stayed on again compressor is off in that situation.In order to charge the system the compressor must run.I unplugged the switch that goes to side of the condensor (pressure switch) tried to jumper it @ the connector and nothing happened,no compressor turn on. Any ideas?
