Either the clutch fluid level could have gotten low allowing air into the lines or you may need to replace your clutch master cylinder. Try adding DOT3 brake fluid and then pumping the clutch pedal. If you start to notice some resistance then you need to bleed the clutch hydraulic lines.
I would guess normal wear. 256K miles is a lot for a clutch. Shoot, 256K miles is great for most any car. I hope mine is running well at 256K. I'm only at 209k.
A worn out clutch release bearing would cause a whining sound when you put your foot on the clutch.
A slipping clutch.
Oiling the a/c clutch will cause the clutch to slip and burn up........
bad clutch cable, or not enough oil on the clutch plates.
Maybe the compressor clutch is not being sent power from the switch in the cab. I'd yank the panel out and have a look at the switch. FriPilot
There is no hydraulic fluid in the transmission. However, there is hydraulic fluid in the clutch system. If the clutch fluid reservoir is empty it would cause clutch not to operate.
Slack in the clutch release or clutch basket. It might adjust out.
cause when you let go of the clutch the wheels start turning. holding the clutch keeps it in neutral.
BAD clutch slave cylinder, wore out clutch and pressure plate.
If the clutch fluid reservoir is just low, no. If the clutch fluid reservoir is empty, yes.
Yes is can if your clutch becomes on fire. make sure to replace your clutch every other day.
