Day 4: Air conditioning is back

Step 1: curse gently under breath 

Step 2: check fuses

Step 3: grumble a little that all the fuses are good because, really, that is a good thing

Step 4: open hood, unplug and reconnect any wire that looks remotely attached to the air conditioning

Step 5: smile nervously after the air conditioning starts working again because you really didn't fix anything
