Hello all, can someone help me with my Climate Control Retrofit issue?
I recently retrofitted my 2007 e60 (530i) with CIC unit from a e90. The retrofit seems to have gone well for the most part (all available functions are working)
I think decided to retrofit the climate control module with one from an LCI donor car. I did this by cutting the wire at pin 21 connecting the side going into the harness to ground and the side going into the connector (Blue Connector) to 12v+ to stop the radiator fan from running at max speed.
After completing that and adding $534 to the car's VO my A/C no longer gets cold, it's like the setting is somewhere in the middle between cool and hot but more on the hot/warm side. No matter how low I turn the dial it never blows cold air. It's as if the compressor is not being triggered (I ran some diag with ISTA+ and it say "ECU responding properly")
I think it's something with the coding, but I don't know what exactly and hoping that someone on here who has done this before can help.
HELP PLEASE summer is coming
Any help is appreciated
