While The Boss has been off doing family stuff, I have spent the last couple of weeks as a Bus Barn Junkie, walking around and putting my nose into where it doesn't belong at several converters down here in Florida.

One of the observations I have made is that there are a lot of condenser units being replaced on coaches which are more or less 10-years old.

The owner will find that when switching on the Cruise that the compressor goes on, you can see the amperage draw, but no cool or hot air (depending on the setting). I had previous thought that such units were more or less bulletproof, but apparently the condenser units are not.

There are likely some wizards around who may be able to enlighten us further.

So, here's just one part of the puzzle and it seems it may be a good idea for us to explore it more fully.
