The most common causes that hinders normal operation of air conditioning system on your BMW 228i are dirty cabin air filter, refrigerant leak, dirty or clogged condenser, dirty or clogged evaporator, bad blower motor, defective compressor, faulty blend door actuator or any fault in the electrical system. 1. Dirty cabin air filter.
TheEinstein. When the A/C is running, the low side (larger of the two A/C lines) should be sweating. If no moisture accumulation (condensation) is appearing on the line, it may not have a pure refrigerant charge. If it is covered in frost after running, that is a sign of low refrigerant pressure.
1. No air flow in any setting. Digital works perfect and I hear the compressor kick in. Blower not coming on. 2. Checked the blower fuse and AC fuses they have continuity. 3. Changed the resistor; still nothing. 4. Read the new resistor in low speed 3-4 volts DC, then in high 11-12 volts DC.
