Blower motor always on!

If by manual controls you mean the fan speed on the AC controller then these do not work. Also ironically the only way to get heating in the car seems to be without the fuse as hot air will seep in from the air vents when the engine heats up. With the AC on it seems to only blow slightly cool air, regardless of temperature settings.

Other 2 codes because FL AC unit uses CANBUS for communications with the rest of car but PF car does not have CANBUS and uses K-line + separate signal wires. So you would need to fit CAN gateway that will translate signals.

I've ordered a regulator, I'll keep this thread updated with results when it arrives. As for the CANbus, any idea if there are any adapters available or would I have to make one myself? Tried googling for one but seemingly no hits. I guess the preface one isn't standardized or anything so I'm fearing the latter option..
