First you have to make sure the fan is working properly. If either the
coolant temperature gets too high, or the high pressure on the A/C gets
too high, then the computer will shut the A/C off. Then make sure air
can flow through the rad and condenser (not block by leaves or
garbage). Unfortunately, after that you need to hook it up to fancy
electronic tools to check what various sensors are reporting.
