Took the Prius in for 5K service. While there I asked them to check out the A/C system. The A/C would cool but not get cold. I confirmed this by sticking a meat thermometer into the vent. I would get 60 degrees, maybe 50 at night if I was lucky. I did not know if this was normal for the hybrid with a belt less system. After picking up the Prius, the notes mentioned that the A/C system was operating within normal parameters and the Prius was run for 5 miles and the temp hit and maintained 40 degrees. No repairs were performed on the A/C system. As I got into my car, I started it up and turned on the A/C. As I was readjusting the seat, I noticed that the air temperature was noticeably cooler. (INTERESTING) I pulled out the thermometer and put it back into the vent. As I hit the freeway....40 degrees. I know that there had to be an adjustment done. I suspect that the heater valve was adjusted to make sure that it was 100% closed. What I find interesting is that the tech said "operating within normal parameters" and I get the car back with the A/C working better. Just what are they afraid of?
