Hopefully it doesn't leak out the cans I just added. 
a/c clutch not engaging...
a/c clutch not engaging... Howdy. I tried searching, came up a little empty handed. My a/c clutch recently just stopped engaging at all. I've replaced the relay and checked to make sure the wires that plug in to the front of the compressor are still good. What else should I check? What would suddenly just make it stop engaging or even trying to engage like that? Thanks for any replies.
did you actually check and make sure that your getting voltage at the connector that goes to the AC compressor?? If it is getting voltage...than its possible that maybe there's a cut-out switch that is bad or something

yea...if it was low on refrigerant that would keep the compressor from turning on. I'm almost positive that there is a trinary switch that protects the system from excessively high or low pressure..either way dont put any of that stop leak stuff in there...it will cost you more money in the long run because that stuff will contaminate recovery machines. Unfortunately it will leak out the cans you just added..it may take a little while, but it will leak it out. The refrigerant really cant just be depleted, if its ever low on refrigerant..than there's a leak somewhere. A test that you could do, is some places sell a dye you can put in the system, you than run the system and use a black light and look for the glowing dye...its real accurate and its a cheap way to find a leak.

yes..if you find the leak, assuming its one of the lines, you can just replace that line. Technically speaking, anytime you replace a component, your suppost to evacuate the system, to remove as much oil/moisture from the system as possible, than fix the problem, than recharge the system with the correct amount of oil/refrigerant. I'm sure though if your in a bind, you could just replace a line, and than recharge the system and call it a day, it may be a good idea though to hook it up to a recovery machine and add a little bit of oil back into the system to compensate for whatever may have leaked out.
