AC/Vent squeak - only when vent on

Jan 22, 2004 4 Replies

I have a squeak that is directly related to my vent system. When the vent is on, I get a squeak or chirp. It increases with RPM, and also when I increase the vent flow. The only time I can get it to stop is with the vent at full blast or off altogether. Any idea what this is?

The obvious thing would be to check for a foreign object in the duct work. Leaves and other garbage is sometimes sucked in. Think of it like a kazoo.

Sorry to the group, I must be a bit tired and my grammar is off this evening.

I've had that happen before (on a different car). This is definitely a different sound. It's a squeak - not a 'leaf in the vent' noise (I'm not sure what the adjective is for that).

It also seems odd to me that it is related to the engine RPM.
