AC Blower Unit

WOPALX · 11-03-2009, 04:50 AM

Got into the car this evening and cranked on the ac due to the heatwave.

Appears I have an issue with the blower unit as it sounds like a turbo prop plane when I turn the ac on.

Anyone had similar issues?

Think I have found the issue.

I removed the hvac filter and looked at the blower with a torch. There is a pretty solid piece of plastic jammed in the vanes, don't know how it got there

Looks like the plastic piece is from the back of the cover that supports the hvac filter, there is a couple of plastic locating bits and one has broken away.

I managed to dislodge it with normal pliers but they were too short to allow me to remove it completely. So I'll need to get the long nose ones out tonight to remove the piece fully as it's now just sitting in the fan loose.

At least there is a 50% improvement such that it sounds like a turbo prop plane at cruise not take off
