Silverado 2500HD debris noise at high fan speed

Postby TX2500WT [OP] » Jan 03 2013, 9:39pm

Hey there,

I have an 03 Silverado 2500HD. When running the AC and heat everythgin works perfectly. When I use the higher fan speeds (like 4 and 5) you can hear what sounds like debris, leaves, something, coming from the dash near what seems to be the passenger side footwell. I am assuming leaves or other junk has gotten in through the cowling on top of the engine near the windshield. Does that sound abour right and more directly, how can I get it cleaned out?

Much thanks from the big "D"

I think they discontinued the filter in 03 so you might have one/might not. Check passenger side, under that plastic cover. The blower motor is there and filter if you got one, cant remember if 03 got it or not... If so it was the last year. Yes leaves get in there...
