Air conditioning compressor/Fan died

My A/C fan and compressor stopped working suddenly the other day, just refused to turn on. A/C clutch does not engage, i have the fan hardwired to a switch in case i really need it so im guessing there is a sensor or fuse or relay blown somewhere, i have no idea where to start looking. I'm assuming the two are related, any ideas as to what could be the problem?

your elect fan runs when your a/c compressor kicks on and when you get above 218*+/- . does it kick on from temp rise ? or have you jumped a wire to the fan to see if it still works ? Take it to an a/c shop and have them check your freon levels and pressures to see if your compressor is shot.

There is a fuse and relay for both the A/C and the aux fan in the fuse box under your hood. Each item has its own relay and fuse. Those fuses are an easy thing to check. In my 91 XJ they are the two fuses and relays closest to the firewall.

I think you should see a relay and a small plastic fuse in front of the relay. The fuse is toward the passenger fender from the relay for each relay on my 91. I have not looked at a 93 to see what that fuse box looks like but I know a 97 is completely different in layout.

the fuses and relays are all intact, it does seem like a fuse blew or something though because they just stopped working suddenly, no weird symptoms or sounds/smells before

if the compressor was shot i think the clutch would still engage correct? and would the compressor failure cause the fan to die also?
