Thus, the air conditioner of the car is responsible for providing you with a comfortable and safe drive for prickling the heat and humidity from the car. If the AC is not functioning properly, it will create discomfort in the cabin because it is blowing hot air out of the vents. Without a well-functional air conditioning system, the BMW heat up quickly and put you and your passengers at risk. The following slide defines the common causes behind the AC failure in the BMW X3.

1. 5 Common
Causes of BMW
X3 AC
Failure in San Francisco

2. Generally, it’s no fun being stuck without
air conditioning on a hot summer day.

3. Thus, the air conditioning
system of the BMW X3 is made
up of 3 main parts such as:
Compressor
Condenser
Evaporato
r

4. They all work together to
move the refrigerant through
a high/low-pressure closed-
loop system.

5. If your car’s A/C is only kicking
out hot air, you should take
steps immediately to fix it.

6. The following points define the main causes
behind AC failure in your BMW X3.

7. Malfunctioned
fan

8. In general, the condenser
system fan circulates the
air through the coils.

9. If the fan malfunctions for any
reason, then it will produce warm
air inside the car.

10. Bad expansion valve

11. Moreover, the expansion valve
is the core component of the
air conditioning system.

12. Due to the bad expansion valve, the
insufficient refrigerant will flow
and overheat the evaporator.

13. Leaking refrigerant

14. Every AC system has a refrigerant
to absorb the heat inside the car
and produce cool air.

15. The air conditioner stops
working effectively when the
refrigerant leaked due to:
Loose connections
Corroded heat
pump

16. Failed evaporator

17. If the AC starts
blowing hot or
warm air, then
check the
evaporator by a
mechanic.

18. A faulty evaporator will cause your
air conditioner to repeatedly
switch between hot and cold.

19. Bad condenser

21. Dust and grime may block the
condenser and overheat the air
conditioning unit.

22. If you feel your air conditioner
is faulty, it could malfunction
the components.
