Tested the ac last night and it was working. Blew out cold air, but maybe for only 5-8 mins then it stopped working again. This is the case actually, it's not that it doesn't work, it will only work for the first few minutes after turning it on then it stops.

When it stops blowing out cold, see if the compressor cuts off. When mine did this, the aux fans weren't turning on. Turned to be a blown fuse.

I found the problem by putting my gauges on and watching the high pressure. When it climbed up, the aux fans failed to turn on to lower the pressure, so the high pressure switch at the drier/receiver cut the compressor off. Replaced the aux fan fuse and no problems since.
