I recently had a front collision repairs on my 2002 BMW 325I and I seem to have a problem that may or may not be related. My coolant light is on, I put an OBD II on it and it had a 0X22 code and said (34)Heating vent and air conditioning front load sensor short to ground >no DTC detected at the time. Don't know if that refers to a short circuit of the line or if its just the sensor. If so where is the sensor located? Now the A/C is also acting up and only blows cold air from the drivers side vent, the middle and the passenger side vents are blowing hot air, are these 2 issues related??
