I have a very reliable, gas-sipping 1997 Sentra XE that we all dearly love. Problem is that the clutch pedal is very hard to push all the way in. It also doesn't return out as far as I think it's supposed to. It shifts okay when you muscle the pedal down, but my wife can't even start the car because the pedal is so hard to get to the floor. I haven't attempted any repair and the Haynes manual doesn't suggest diddly squat. I'm also not finding much with an internet search. Any help would be greatly appreciated.
