My 91 RAM van 250 conversion by "Primetime" the blower and pwr windows quit working, but everything else works electrical. I checked all the fuses in the glove box and under the steering column. Is there another fusebox under the hood? Anyone have a fusebox diagram for the 91 RAM van 250? Could a fusible link be blown?

 

I would suspect a fusible link since you don't have a power box under the hood.
