A worn out clutch release bearing would cause a whining sound when you put your foot on the clutch.
if I understand the question you asked correctly, I would say you are in need of a clutch but it might need adjustment but not likely.
sounds like clutch needs adjustment or time to replace it
Probably do to a bad pressure plate and or clutch plate. I would first check linkage adjustment and slave cylinder before changing clutch.
Compressor/clutch is about to go bad, if has a serpentine belt when it does no driving the car, better get it checked while car can drive, oh ya stop using AC till its checked.
I'm not a mechanic / technician but I believe that would be a throwout / release bearing problem on your clutch
Could be clutch cooling fan engaging
the ratchet on the brakelight switch needs pulling out a couple of clicks mine was the same.
A worn belt can make a squealing sound with the motor running. A seized clutch can also make this sound.
needs new clutch pressure plate and throw out bearing
I'm not quite sure how youare hearing that if you are pressing the pedal, more likely the click is the clutch switch clicking that allows you to start the vehicle, if it truly is the slave cylinder, down on the bellhousing making the click sound it could be loose, or making a clicking sound as it connects with the clutch lever.
It would sound like the throw out bearing is bad.. That is usually replaced with the clutch and pressure plate. The throw out bearing applies pressure to the pressure plate and releases the clutch disc. When not applied, the bearing spins freely, and a noise would indicate a dry bearing.
