Sproing…
That’s the sound I heard the other day when pulling out of the driveway to head to work. Not long after I heard something fall on the floor of my car by my feet, over by the clutch. My first thought was that the clutch spring had broken, so I pumped the clutch a few times and it seemed to work.
When I got home from work that evening I took a flashlight and looked under the dash. Sure enough, there is a small spring behind the clutch pedal, and it had broken (snapped off) on one side. I snapped a picture and emailed it to my service guy, and he sent back an estimate.
Part: $20
Labor: $110 
Total: $130
I’m not sure why the labor costs are so high. It doesn’t seem like it would be a big job to replace.
I may try to fix it myself this weekend, which is probably a sure-fire way to ensure that I completely screw it up. 
If I do manage to fix it, I’ll post pictures.
