It's always a challenge to diagnose and repair those weird driveability problems, but any full-time tech will tell you that the more routine jobs are the ones that fill your day: brake work, minor maintenance items and, of course, A/C repairs. In my part of the country, keeping customers' A/C systems up and running is a year-round request.

A simple A/C repair

By the time I got it in, cold air was already blowing hard out of the front center ducts. So far, it seemed like the basic A/C system was working OK. But today was an exception to our warm winter, and the outside air temperature was in the low 50s. More complete testing was in order before I could conclude that the system was working as well as it should. And so far, I didn't hear the noise the customer was complaining of.
