We have bled the lines on a 1994 gmc sierra and are getting no tension in the clutch what do we do?

It takes a lot of bleeding, keep bleeding it off, make sure your hose clamps or nuts are tight, sometimes there's an o-ring where the hose is, check to see if yours has one, but you have to bleed the system thoroughly

it will short cycle while refrigerant is being added slows down when level starts to reach normal

Yes, you can the complete set from www.rockauto.com for under $100.00

depending on witch compressor you have they all are very straight forward , just remove the screws that hold the out side plate to the electric clutch and find the screw that holds everything together in the center ,remove it and it should slide out with no problem. get a replacement and install it the reversed way

it is very easy to replace the parts, bleeding the air is the real problem, u will need to buy a Mityvac brand vacuum clutch bleeding tool, with out it you will never get the air out of the system after the parts are replaced, also always replace the clutch master and the clutch slave at the same time.

check under your master cylinder,is there another clyinder below with one line in and one line out,if you do I found this is for the Abs to the rear,I had to replace this it was full of air,and did exactly what yours is now

Could be a throw out bearing or the shift fork is broke.

Probably blew the rubber diaphram in the clutch master cylinder. Rebuild kits are fairly cheap and easy.

With the hydraulic systems, there is no adjustment. So what pedal travel you have is likely normal for that vehicle.

could be wrong here but sure sounds like its out of fluid at the "master cylinder" look near the brake master cylinder for a seperate little container for the clutch. bleeding is tricky because it is small and wants to run out of fluid quick. you have to keep adding each time you bleed. Hope I helped. Thanks
