It is also common, particularly in Chryslers, for the front seal on the=20
compressor to degrade, and the refrigerant to leak out through the=20
shaft. It happened to me. TWICE.
Chrysler even has a note in their owners manual telling you to run the=20
A/C monthly to keep the seals wet with oil. But who runs A/C in winter,=20
particularly when you have 9 months of it here.
They SHOULD have programmed the engine controller to run the A/C every=20
10 starts or so.

Yet another system made by monkeys.
