Hi,
I am looking for some help in identifying the cause of a whistle in the passenger footwell (RHD car). It is related to the aircon as it only occurs when the a/c is on and stops immediately when the a/c is switched off.
The car is a C250TD w202 estate.
The whistle starts when the engine revs reach around 2500 and stops when the revs fall.
The whistle does stop if the revs climb to over 3000
Any ideas before I start to pull the car to pieces?
Many thanks
Al
