2010 Prius IV - Hot AC when Engine Runs
Recently bought a 2010 Prius IV with 132k on the clock and it runs beautifully.
When I got in it I noticed the AC was nice and cold and didn't think too much on it.
Purchased it and drove away.
Shortly after, however, I noticed that whenever the engine ran the AC would no longer blow cold.
Checked it at idle with engine off, and AC gets down to ~40 degrees, but gets up to over 90 with the engine running and changes over to hot almost immediately once the engine runs.
I checked the codes on the AC itself and it has error code 23, but I don't believe the sensor is malfunctioning. The compressor is running when the engine is either on or off.
I was thinking maybe a blend door issue, but not too sure on that one.
As soon as the engine turns off the AC starts to get cold again.
I noticed that part 063800-1100 (Factory AC Heater Servo Regulator) does not move at all.
Like... Can't even move the gears attached to it by hand. Super stuck.
Would that cause this issue?
Thanks for the help in advance.
