My Cultus 2008 has unsatisfactory AC blower performance.
I had the AC fully serviced at the start of this summer.
As a DIY enthusiast, I recently removed the blower box and serviced the blower myself.
I opened the top of the blower, added lubrication (now the blower spins freely without any disturbance), and cleaned the motor with WD-40, as it had a slight carbon buildup.
But the problem remains: the air is cold, but it doesn’t hit your face. You can feel the coolness, but there’s barely any airflow.
One thing I noticed during my DIY blower servicing is that most of the air is being leaked out of the blower intake area. I will attach an image of what I am trying to reference here, rather than going into the cooler box where the AC coil is located.
So while the blower seems to generate enough pressure, a lot of it is leaking out from the top, right where it should be drawing air in.
Another issue is uneven airflow from the vents:
- Passenger side duct: strongest airflow
- Middle passenger duct: slightly less
- Middle driver duct: even less
- Driver side duct (far right): almost no airflow
What can be done to address the minor issues I am facing?
Another question on the topic.
Can I DIY the cooler box without losing refrigerant gas? Or am I at the mercy of the “ustaads” who say the entire dashboard needs to be opened and quote 7,000–8,000 PKR for labor? I’m in Islamabad.
For those who might be interested in servicing the blower, here is the video that I followed
