Ready to fix your A/C? Good. Pop the hood and find the vacuum line that goes to the outlet labeled "A/C" on the main vacuum tree(on the drivers side of the firewall). It is a hard plastic line and it has a crack in it. Replace it with some rubber tubing that has the same inside diameter. Now you will have fixed the problem and you won't have to put those stupid rubber ends on the plastic line. I put some corrugated plastic tubing around my hose to protect it from weathering. Good luck.
