i have a 1998 c1500 305 with an a/c issue. i tried sealing the system and than recharge is with a/c pro, and it worked for a little while but it no longer works. the compressor clutch keeps kicking off and it wont hold a charge. im pretty sure i need to replace the compressor because all the wires are good no frayed ends or anything. if this doesnt fix the issue how do i fix the lines or replace them without having to take it to a shop (short on cash). thanks in advance

 

The compressor cyling like that means you are low on freon again. You've got a leak somewhere (not to say that it isn't the compressor leaking).

Look for an oil track or have a shop diagnose it with a sniffer. Leaks are pretty easy to find tho. They always leave that oil track at the source.

It needs to have the gauges put on it to verify if the freon is low. If it is, use dyed freon, that will help identify where the leak is.
