IT HAS BEEN MY EXPERIENCE WITH OLDER VEHICLES THAT WHEN THE CLUTCH PEDAL "CREEKS" THERE ARE SOME WEAR POINTS WHICH ARE NOT GETTING LUBRICATED
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.
The engine might rev up when the clutch is pressed if the driver is still pushing slightly on the gas pedal during normal shifting. It is also possible for the driver to accidentally touch the brake and the gas at the same time without realizing it.
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.
You would here the blade scratching the ice.
I'm not a mechanic / technician but I believe that would be a throwout / release bearing problem on your clutch
the ratchet on the brakelight switch needs pulling out a couple of clicks mine was the same.
Could be clutch cooling fan engaging
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
