By jumping the clutch relay, you can verify that the clutch is actually
working. It also bypasses the High/Low pressure switches which also helps
to verify that it's either the clutch or not. Checking pressures is the
best and quickest way to determine what's going on in the system.
The PDC is the fuse/relaty box under the hood.

Good Morning all,
This caught my attention because I am in Texas where we have had several
days over 100 already and I am experiencing a similar, but not as drastic,
situation. How do you best determine the condition of the clutch and what is
a PDC where one might jump the clutch relay?
Haven't run pressure tests on mine yet. My first inclination was that I
might just need a shot of coolant.
Thanks,
John
