Surprisingly those bad pumps are still out there. Today one failed on a
friends car. Had been on for several years and many miles. I had
driven this car many times, and never suspected it had one. Put a good AC
pump on in its place. The bad pump I could break the diaphragms apart
with my fingers.
Almost like jello. Scary thing is we took the car for a long interstate
cruise out of town just two weeks back.
