K.I.S.S.

This past week in our A/C class, our teacher decide that he was going to give my group the responsibility to figure out why the air conditioning on a "customers" truck wasn't working. So Kera and I discussed what could be the problem... We hooked up the manifold gauge set to verify that there was refrigerant in the system. I went to print off a wiring diagram, and she checked all of the fuses.. we checked the relays.. our next move was to apply power to the compressor to see if the clutch was engaging.. when we applied power, we found out that it was engaging.. so on to figure out what else was causing the problem.. Kera had to leave to go to work, so I stayed over to finish it up.. I rechecked the relays, and then on to the fuses.. Taking another look at the wiring diagram, fuse 23 is the A/C clutch relay fuse. My teacher printed off the CJB fuse and relay information. Come to find out, fuse 23 was nowhere to be found, So we got another 20 amp fuse and put it in the spot it should have been, and the air conditioning has worked properly ever since. All of that work just to find out it was a fuse! So remember K.I.S.S.
