I have an '84 Jimmy with a 6.2 and ac. Last winter I had a little sporatic bearing noise from my heater/ac fan motor. I put off getting into the replacement job, as the noise was mostly evident on really cold mornings. Lately, I've been using my ac each time I jump in my truck and the bearing squaller has become pronounced. Yesterday I tore into the truck with the aid of all of my manuals, all of which failed to depict my fan shroud which covers the fan motor and ac condenser. I've removed all of the visable fasteners, along with the heater hoses and all of the fan electrics. It seems like there must be a hidden fastener retaining the shroud, directly beneath the fan motor, but I'm not sure how to get to it. I have to remove this shroud before I can access the fan motor. Anyone know how to get to the last fastener? Does the inner fender have to be dropped? Any suggestions, aside from destroying the shroud, or just living without heat and ac? Thanks.
