When I bought the car, the ac didn't work. The condensor appeared to have a leak so the system was empty. So i have no idea what sound the ac made before the repair.
I can't believe there is debris in the system, in the oil there was no debris, is was pure oil.
Problem here in Belgium is that every local garage calls himself an ac specialist. In reality they have a fill station that vacuums the system and refill it, and thats it.
It's very difficult to find the reason of this problem, Is it a problem of the ac system? Is it a problem of the power steering pump that is amplified when the ac is on, is it a resonation? I really don't know.
The car has been diagnosed by the dealer, an a Volvo specialist, both have no idea what's the problem.
