i trying to trouble shoot the a/c on a 1996 ford taurus. the compressor doesnt kick on. i have checked the fuses, both inside the cab and engine compartment, and have found none that are bad. i have also tried jumping the low pressure, and high pressure switches. the system itself shows full. i thinking maybe the relay but i cant seem to locate it? any body know are have a pic of where it is? or have other ideas what it could be. thank you.
