I'm trying to troubleshoot my AC system. The AC was working the last time I used it, which was last fall, but over winter, something went sideways from lack of use. Now all I get is the three LED flashes and no AC.
I checked the refrigerant pressure, its good. The temperature is warm so its not a --too cold to operate-- thing. I replaced the AC relay, no effect so I put the old one back in. The AC fuse is good ( continuity across the terminals with the fuse removed), however I'm noticing there is no voltage at the fuse terminals.
So my questions are ...
Does anyone have the electrical schematic of the hybrids AC system?
The AC compressor is powered by the 300V system, is there a high voltage relay somewhere?
Are there high voltage fuses for accessories that use the 300V system?
Which temperature sensor is the sensor for the AC system? ( I think I saw two behind the grill - driver side and passenger side of the radiator frame)
Which "radiator" fan switches on when the AC system is activated ( driver side or passenger side )
Thanks in advance....
