mi2kimi,
The picture you show is 2 cables or 3 cables? Where it connect to. Actually i troubleshooting the BT 6 speeds A/C. Previously it don't connect to heater, my A/C is condensate on the grille inside the car when long distant travel. After i connect the heater back from the engine block it only have heating no cooling although the compressor is running. So still looking for the device to control the heating coil. Any sifu have advice on this ?
