Mercury Tracer vibrates when aircoditioner is running?

If your Mercury Tracer vibrates when the air conditioner is running, it could be due to several factors such as an unbalanced compressor, loose mounting bolts, or a worn-out engine mount. Additionally, issues with the AC system itself, like a failing blower motor or debris in the fan, could also cause vibrations. It's advisable to have a mechanic inspect the vehicle to diagnose the exact cause and prevent potential damage. Regular maintenance can help mitigate such issues.
