Simple fixes you *might* be able to handle:
* Low refrigerant: This is a common cause of a non-functioning AC. However, adding refrigerant yourself is generally not recommended unless you have the proper equipment and knowledge. Improperly adding refrigerant can damage the system. A leak needs to be identified and repaired first.
* Blown fuse or relay: Check your owner's manual to locate the AC fuse and relay. Replacing a blown fuse is straightforward.
* Faulty blower motor resistor: This controls fan speed. Replacing it can be relatively easy, but requires access to the blower motor and some electrical knowledge.
* Loose or disconnected electrical connections: Inspect wiring and connectors related to the AC system for loose connections.
Fixes requiring professional help:
* Compressor failure: This is a major component and expensive to replace. It's best left to a professional.
* Refrigerant leaks: Locating and repairing leaks requires specialized equipment and knowledge. Using leak detection dye and UV light is common practice.
* Condenser or evaporator coil issues: These are complex components that are difficult to access and repair.
* AC clutch problems: This engages and disengages the compressor. Diagnosis and repair require specialized tools and knowledge.
* Control issues: Problems with the climate control panel might need professional diagnostics and repair.
Before attempting any repairs:
* Consult your owner's manual: It might provide troubleshooting tips or diagrams.
* Research the specific problem: Use online forums, repair manuals (like a Haynes or Chilton manual), and YouTube videos to learn about the issue.
* Gather the necessary tools and safety equipment: Working with refrigerant requires specialized equipment and safety precautions.
In short: If you're comfortable working on cars and have some mechanical experience, you *might* be able to tackle simple problems like a blown fuse or a faulty blower motor resistor. However, for anything more complex, it's strongly recommended to take your Mystique to a qualified auto mechanic specializing in air conditioning repair. The cost of professional repair will likely be less than the cost of misdiagnosing and improperly repairing the system yourself.
