I have a 2009 Town and Country and the A/C clutch will not engage. I have checked the system and it is full with no leaks. Also there is battery voltage at the connector, I have noticed that the voltage is there all the time even with the vehicle off. Additionally the blower motor seems to make a clucking noise for a few seconds when its first started sometimes and I have also herd the noise while the vehicle is off. Thanks in advance for the help.
