1999 A/c Problem

[folsomj]

1 month ago the a/c wouldn't work, so I add 1 can of R134a. That lasted 3 weeks. So I took the dryer, low side and high side lines apart. Checking all O rings and the filter. All checked good. Took car to the shop to have it recharged, worked good for about a week. Now it acts like all the pressure is stuck on the high side. Does anyone have any suggestions on what to do next?
