1. Fill master cylinder reservoir with DOT 3 brake fluid. Raise and support vehicle. Attach bleeder hose to bleeder screw on bleed line of slave cylinder. See Fig. 1 (attached in link) . Place other end of hose in glass container 1/2 full of brake fluid. Loosen bleeder screw while holding bleeder screw fitting.
2. Have an assistant depress clutch pedal to the floor. Tighten bleeder screw and release clutch pedal. Repeat bleeding procedure until fluid entering container is free of bubbles. DO NOT allow reservoir to run out of fluid during bleeding. Refill clutch master cylinder reservoir.

There is a bleeder on the drivers side of the transmission follow the tube from the clutch master cylinder if you cannot find it. Pump the clutch up and hold it down then open the bleeder repeat till air is gone. May have to bleed again after driving a bit. If you want to bleed the clutch master cylinder run a tube from where the line goes into the cylinder and take the cap off and run the tube into the fluid (make sure its in the fluid) then pump the clutch slowly until no air bubbles. I just replaced my clutch master cylinder this is where the information comes from hope it helps you out!

U have what is called a hydraulic clutch, one of the hydraulic cylinders hs failed, there is a master and a slave cylinder. The most likely and most common cylinder to fail is the slave cylinder, this requires the transmission to be pulled out to replace it. the art is around $125.00, while the trans is out u might as well replace the clutch, the labor is about the same. Here is a picture of the part, let me know if u can see it.
