what number is the compressor fuse
when the refrigerant gets low or leaks out on an A/C system, it won't turn on, to protect the compressor. That might be your issue. Have the system recharged and checked for leaks.
These are the fuses associated with the a/c system functions: F16 and F21 inside the relay box under hood, F7, F11, F20 and F21 in fuse box under dash.
