thanks, I know about the fuses and the ecom button, the kids are using it that way now. I was just trying to figure out how I could run the heat with out the ac. if you unhook the compressor at the clutch it will not let the motors under the dash blow, so I hooked up the clutch and cut the belt off and still do not have blowers. the red fuse is good but I am not familiar with this thirty amp fuse you spoke of.
