When depressing clutch on a 1993 Nissan Stanza the clutch goes to the floor and cannot shift into gears What might be the cause?

Answer 1

Since I am not experienced with that make and model, this answer will be generic in nature. Most vehicle clutch system are similar in nature, and all use some kind of "linkage" between the pedal and the clutch assembly. The cause of the symptoms you describe suggest a failure of the linkage which connects the clutch pedal to the clutch itself. There are two types of linkage: the older mechanical, and the new style hydraulic. The older mechanical type uses either a rod, or a cable to connect the pedal to the clutch. If your vehicle has one of these, then the symptoms you describe suggest that a connector has come loose, or a rod or cable has broken. The newer vehicles use a hydraulic linkage system consisting of a master cylinder attached to the pedal, a metal line between and to the clutch assembly, and a slave cylinder at the clutch, to actuate the clutch. Again, the symptoms indicate a failure in this linkage "chain." The failure could be any one or more things in any part of this chain. Some of these include a leak anywhere in the system which allowed the hydraulic fluid to drain out, or a failure of a seal in either the master cylinder, or the slave cylinder. The "fix" for this is to first examine and analyze the entire system to determine and identify the defect which caused the problem. Once the defect has been identified, then repair or replace the part responsible. Do NOT make the mistake of trying to fix the problem by simply replacing parts one at a time, as this can become very expensive and a lot of work IF the defective part just happens to be the last one you get to.j3h.
