    I replaced the water pump and thermostat. Stupidly, when I took the connector for the AC compressor out, I didn't cover it with plastic. So, when I disconnected the hose from the thermostat housing it filled the ac compressor connector socket with coolant. I blew it out with a can of air and it looked dry. I got everything put back together and went to start the car. The AC was blowing hot and the Check Hybrid system message came on. Would the coolant spilling into that connector socket be enough to kill the compressor? Is there a way to test the compressor to see if it's dead? Could I have caused a leak in the AC lines by knocking into them while removing bolts from the water pump?

    This was the pressure. Was the same with car on and AC on and when the car was off.
