Guy from your description it sounds like the blower is running in the opposite direction than most of the later Newells. In my 93 and 98 the blower sucked air from the front side compartment through the louvers into the generator compartment, through the radiator then exited through a duct below the radiator. I wonder if it was designed that way or a previous owner hooked it up backwards for some unknown reason?
