possible clutch gone bad?

[bronsin]

Your clutch is bad if the engine and transmission vibrate a lot when letting the clutch up. Almost no matter how smooth you try to be, there will be vibration.

Another bad clutch symptom is motoring along in gear and when you punch the gas pedal, the engine revs up but the car doesnt go any faster.

The defroster doesnt have anything to do with how well or bad the clutch works.

That burnt smell is another sign your clutch isnt what is should be.

Good luck and tell us what happens!
