Fitted intercooler now air conditioner doesn't work

Hi

I have just completed the installation of a trunk mounted and split intercooler system. Everything seems to be fine with the exception that my air conditioner will not turn on anymore. I am running the power for the water pump in the rear trunk tank off the original power supply to the standard intercooler pump and have disconnected and removed it.

How could I have effected the operation of the air conditioner? I can confirm the heater and fan work ok though.

Regards,

OZZYAMG

Hi

Went back to my mates workshop and connected a Bosch scanning tool and it displayed an error with the eveporative sensor. We cleared the code and reset the computer and the aircon all works fine now.

It seems we must have bumped it whilst working on the car but all is fixed now.

Regards,
