A clutch pedal that sticks halfway in on a 1993 Mazda 626 can be caused by a few issues, such as low hydraulic fluid in the clutch system, air in the hydraulic lines, or a failing master or slave cylinder. Additionally, worn or damaged components like the clutch release bearing or pressure plate could also contribute to this problem. Regular inspection and maintenance of the clutch system can help identify and resolve these issues. If the problem persists, consulting a mechanic is advisable.

I have a 99 Mazda 626 and mine is on the passenger side of the car. Look for a black cylinder close to the firewall. You should find a small screwoff cap on the black cylinder. This is where you connect your hose to add freon. The high pressure and low pressure service ports are different sizes, so you can't get them mixed up and connect to the wrong one. Hope this helps!
