I have a 2003 Suburban and the blower motor can lose and dropped to the kick ;panel and sat there. I thought the motor was shot (started making noise) and I was taking my daughter and her friend to a banquet. They were dress up and hair done so ran the blower I figured what the heck, motor shot have to replace it any way. Bottom line the fan milled the whole mounting flange away! I need to replace the duct work. I now have half the truck tore apart down to the duct. Looks like the bottom half of the duct might separate, looks to be held together with a few screws and what looks like rivet heads make of plastic but it might be plastic weld locations. Looks like it might be attached to the fire wall. Can this be taken apart with out opening the A/C lines? No way to attach blower motor, would like to take this one back! Any one have any experience here? Any information greatly appreciated. Thanks
