Question about 2007 Chevrolet HHR Special Edition
When i was pulling out onto the expressway, i heard a knocking sound coming from the front passenger side wheel. sounded like a bearing going out. could this sound have something to do with the compressor? after the sound my a/c was not cooling.
Upon starting the engine theres already a high pitch noise your compressor pulley bearing is worn out,and if ac was not cooling anymore the magnetic coil of compressor need to be check by ac technician...

The AC compressor shaft is riding on a electronic clutch pack.
When the pressure need to built up the clutch will LOCK and you will see the shaft start spinning.
Start the car and max out the ac. The clutch should lock up within 2 minutes.
Listen for a click sound from the clutch.
A badly damage clutch will lock up the belt!
You DO NOT want to be anywhere near the belt because it will snap.
An AC system should last 3--6 years.
NO using the ac compressor is a bad thing.
Let an AC guy to test the low side AC line pressure.
