I just bought a used Prius. When I tested it, the air conditioner worked. One month after I bought it, I was waiting for someone in the car and the air conditioner worked fine. Later, it stopped cooling. Maybe it even felt like it was blowing hot air. I searched the forum and read a lot, and I felt dizzy. I tried to read the fault code and it showed 00. Now I suspect 1 The hot and cold mixing damper because I really felt that there was a little hot air. 2 The low-voltage circuit plug is prone to problems. Newbie, please guide
2 Supplement 2 Once it didn't cool I tested it again and it worked again I forgot which thread said that after more than 100,000 miles The low-pressure plug of the compressor is of poor quality It is easy to have problems
Try to diagnose the car systems with the help of OBDII scanner and the program in the phone or find the Techstream cable and program for diagnostics of Toyota cars. Your problem may return.
IMHO; get the system professionally diagnosed. It isn't uncommon for cars of that age to lose enough Freon from the system, though seepage, to become intermittent. Hope this helps......
