Should have had a comprehensive diagnosis before the comprehensive
repair.

Sounds like a WAG to me.

Quite true. Even a truism. But how often wishful-thinking replaces solid
diagnosis.

Just curious, could any of those replaced components (evaporator,
accumulator, etc.) been damaged by a chronic undercharge of the system
(excessive and constant freezing up of system for probably 2 years)?
I try to keep my car in nearly perfect condition, and this issue was
misdiagnosed so many times that it persisted as the freezing problem
continued for quite a while. I just want to make sure those parts
were not compromised *because* the shop dismissed the problems for so
long, in which case, making the responsible for their failure. Thanks
again.
