13 GL450 Ac code 91EB15
all codes erase except for 91EB15 Come on,
and ac light blinks when pushing ac button on.
any help and suggestions would be greatly appreciated.




the electronic control valve is shorted, or it is the wrong valve? Need the compressor model to check







The error code is electric, nothing about AC refrigerant flow.
Very common getting a new wrong compressor. If the compressor is not original, and the parts is missing the diode, it will NEVER work until hacked, or use the correct compressor. Post pictures of original and new compressor, and I can tell you. Please include electronic valve too in the photo

What's the hack ? Do you know where the diode would be installed and the value? I did received a new clutchless comp and had concerns about the controller having an Canbus issue.
Original unit was the clutch type, currently I have the clutch signal wire open- I thought of putting 5-7 ohm resistor in place to simulate the coil.
Any help truly appreciated!
thank you
