Re: My Air Conditioning Problem

I disagree with #3
The reason why the heater core is always on except in Max is just for 
that reason and for an added bonus the A/C removes some of the heat 
from the engine cooling system. It also improves the system's ability 
to quickly reduce the humidity inside the car.
On #2 the switch may not be bad, only out of adjustment.
On #1 this is the most common reason for short cycling. Even a tiny 
leak over 20 years will eventually cause even the tightest automotive 
A/C system to short cycle. This can only be determined by getting a 
gauge set on the system and seeing what is going on. You should never 
attempt to adjust the low pressure switch without knowing the system 
pressures.
