HELP!!! I just did this procedure today while wrapping up baselining a new to me 07 lx. 160k no documented AHC maintenance. Things went more or less fine but now AHC is inoperable!!! I turned the truck on the first time after the left side blead and it took about 2 min or so to go from l to n. Turned it back off to do the passenger side quick bleed and when I got back in the truck it would not go from l to n. Previous to this procedure AHC was working and I had 9 grads with just barely out of spec rear pressures and spot on front pressures. I am at a loss. The pump also seems much louder than usual...
I'm getting this code:
c1751 - Continuous current to compressor motor
I've tried the "bleed air of AHC" in case it is suffering from air lock. The ahc does not seem to respond to this procedure. Since doing the procedure I am also getting the
C1762 - Abnormal Oil Pressure for Pump
and
AHC off flashing even with jumper pins removed from the above procedure
in addition to
c1751 - Continuous current to compressor motor
I'm happy to dig in techstream for some other data if it would help. Sounds like by super bad luck my pump went bad at the exact same time I flushed the fluid but I'm having a hard time believing this...
