Preliminary Checks. Often, an AC performance issue can be tracked down to a simple and common problem you may check for yourself. Check the Belt: The belt should not be too tight or loose.
My AC Is Not Blowing Cold Air. With the engine at operating temperature, turn the AC to "MAX cooling." If you hear a noise, this other post on AC System noises can help you diagnose the problem.
My AC Compressor Clutch Is Not Engaging. When you turn on the AC system, you may notice the clutch doesn't engage. The clutch is the center piece at the pulley, in front of the AC compressor.
My AC Blower Always Blows at the Same Speed. With the engine idling and the AC operating, select different speeds for the AC blower: If the air comes out of the vents at the same speed, regardless of the speed setting.
My AC System Is Not Cooling Right. Most of the time, cooling problems develop from common issues: Debris clogging the radiator or condenser core. Clogged cabin air filter.
AC Cools Air Only When Depressing the Accelerator. AC system pressure issues can lead to an AC system that blows cooler air only when you step on the accelerator, increasing engine speed.
My AC Compressor is Noisy. AC compressor problems that may manifest through different types of noises include: Loose compressor mounts. Seized compressor.
The AC System is Not Cooling. A bad compressor clutch may fail to engage when you turn on the AC system, failing to produce cool air. But the problem may also come from a fault in the electrical circuit or thermostat unit.
AC System Is Not Blowing Air. Another common problem may occur when turning the AC system and having no air coming out the vents. Usually, the problem is with the climate control system
There Is Frost on the Condenser. An AC condenser can develop leaks or become restricted, often shown as frost on the outside of the unit. To check for potential restrictions, head over to the section Checking the AC System for Restrictions.
