Before You Begin:
* Safety First: Disconnect the negative battery terminal before starting any work on the electrical system. Refrigerant under pressure in the AC system is dangerous; do not attempt this if you're not comfortable handling refrigerant. Improper handling can cause serious injury. If you're unsure, take it to a professional.
* Gather Tools: You'll need a socket set (metric), wrenches, screwdrivers (Phillips and flathead likely), possibly a clutch puller, a multimeter (to test the old and new coil), and possibly some penetrating oil.
* Obtain Replacement Coil: Make sure you have the correct replacement clutch coil for your 1999 Chrysler Cirrus. Get the part number from a reputable auto parts store (like AutoZone, Advance Auto Parts, or a dealer) to ensure compatibility.
Steps Involved (General):
1. Locate the Compressor: The AC compressor is typically located near the engine's front on the passenger side, but its exact location might vary slightly on your specific model. Consult a repair manual for your year and model.
2. Disconnect Electrical Connections: Carefully unplug the electrical connector(s) leading to the clutch coil. Take photos or make notes to remember how everything goes back together.
3. Remove the Clutch: This is often the trickiest part. You might need to use a clutch puller to separate the clutch from the compressor shaft. Some compressors may allow you to remove the coil without removing the entire clutch. Penetrating oil may help loosen any seized parts. Be careful not to damage the compressor shaft.
4. Replace the Coil: Once the old coil is removed, carefully install the new coil, ensuring it's properly seated and aligned.
5. Reconnect Electrical Connections: Carefully reconnect the electrical connector(s) to the new coil, making sure they are secure.
6. Test the System: Reconnect the battery. Use your multimeter to verify the new coil is receiving power and has the correct resistance (check the specifications on the new coil). Turn on the AC system to check if the compressor clutch engages.
7. Recharge the System (If Necessary): If you had to disconnect the AC system to perform the repair, you will likely need to have the system recharged with refrigerant by a professional. This is essential for the AC to work correctly and to prevent damage to the system. Releasing refrigerant into the atmosphere is illegal in many places.
Important Considerations:
* Repair Manual: A repair manual specific to your 1999 Chrysler Cirrus is highly recommended. It will provide detailed diagrams and instructions.
* Refrigerant: Again, handle refrigerant with extreme caution or leave this to a professional.
* Professional Help: If you're not comfortable with any of these steps, it's best to take your car to a qualified mechanic. Improper repair could lead to more extensive and costly damage.
This information is for guidance only. Always consult a repair manual for your specific vehicle before attempting any repairs. Improper repair could damage your vehicle's AC system or cause injury.
