2004 Pontiac Grand prix ac grinding noise Sign In

When my ac is on, sometimes I hear a terrible grumbling/grinding/purring noise from under the glovebox. The only way to get it to stop is by shutting off and turning back on my ac. I find that these noises are triggered when I hit a bump in the road or I make a sharp turn. Any ideas on what may be the cause?

? You are probably hearing the blower motor and fan speed should change the noise. If so a new blower would usually be the fix,

I'd pull the blower motor out and make sure there is nothing caught in it before replacing it.
