Clutch pedal

My clutch pedal sticks when I drive. It started during the cold weather. My husband checked fluid level & was ok. He sprayed WD40 on clutch pedal but it did not make any difference. Is this just related to my pedal or is my clutch going bad?

You might have corrosion inside your clutch master cylinder.
How old or how long has it been since you’ve had service on the clutch?

To avoid future damage have the clutch (and brake) fluid changed every 3 years or so.
