it worked last week great today nothing.

is there a fuse somewhere?

any ideas where to start looking for the problem?

 

Did your blower quit or is it not blowing cold air anymore? If it is the blower I'm sure there is a fuse somewhere or maybe the motor burned out. If it isn't blowing cold air start with the compressor and make sure it is cycling. If I remember correctly there is a high side and low side A/C lines, with the air on touch both of them, one should be really hot and the other should be really cold, if they are about the same you probably need more freon. If your A/C was working fine and just quit and the compressor is working fine you might have sprung a leak somewhere and will have to get it tested. Also make sure your electrical connection is connected on your compressor. Hope this helped...
