My 05 prius is not blowing cold air. I want to try to charge it myself before I take it in to the dealership. The problem is I see the high pressure port by the wiper fluid, but I can't find the low pressure port. Does anyone know where it is or a diagram of the air conditioning system?
Be sure to use a Toyota approved oil! The compressor motor windings are exposed to it; the wrong oil can eat away their insulation and ruin the motor.
