  Q: How to Service and Repair an A/C Clutch on Chrysler Cirrus?

  A:

  To begin, disconnect and separate the negative battery cable and after that, get rid of the serpentine Drive Belt. Remove the connector for the compressor clutch coil wire harness and then unscrew the four bolts that hold the compressor to its mounting bracket. After that, take the compressor out, holding it in the engine compartment while you work. Through the clutch plate holes, fit both pins into place with Special Tool C-4489, then rotate the stationary clutch plate to loosen and remove the hex nut. Use Special Tool C-6461 to unfasten the clutch plate after that, then extract the compressor shaft key and the clutch shims. Snap the external front housing snap ring off, slide the tool C-6141-1 lip into the proper groove and insert the shaft protector (C-6141-2). Insert the special Tool C-6461 through the puller flange into the jaws and tighten them both clockwise until you can free the rotor pulley. The screw and retainer should be taken off the clutch coil lead wire harness on the compressor front housing. Then remove the snap ring from the compressor hub and unhook the clutch field coil. Examine the wear on the clutch friction surfaces by checking both the pulley and front plate. If either is damaged, replace them. See if there is oil at the front cover, shaft and nose end of the compressor; a wet front cover felt tells you the shaft seal is broken and the unit should be replaced. Look for roughness and unnecessary grease from the clutch pulley bearing; if either is found, replace it. First, attach the clutch field coil and the snap ring so that the clutch coil lead wire harness retaining clip can be added next, secured to the compressor front housing by a retaining screw. Place the rotor assembly squarely over the front compressor housing hub, attach the pulley bearing assembly using Special Tool C-6871, install the installer on the shaft and turn the nut until the assembly is set correctly. Fit the front snap ring pliers on the snap ring, with the bevel side facing away from the dowel and press it to be sure it is in place. Put the compressor shaft key and original clutch shims onto the shaft, then fit the clutch plate using Special Tool C-6463 and tighten the hex nut to 14.4 Nm (10.5 ft. lbs.) Using a feeler gauge, make sure the clutch is slightly below or equal to 0.79 millimeters (0.031 inch). When there's an uneven air gap, lift the hinge slightly at the smaller areas and press it down harder in the wider areas. When the installation is finished, set the heater-A/C control to Recirculation Mode, the blower motor switch to its highest speed and begin cycling the compressor clutch twenty times (five seconds on and five seconds off) at engine speeds of 1500 to 2000 rpm to improve compressor clutch performance.
