97 Z28 P1641Dand P1642A My 97 Z28 is throwing these for the fan 1 and fan 2 relay control circuits. Every one i read when u put the ac on the primary fan comes on. Mine dont. The relays are all good and i also replaced the coolant temp sensor what could the problem be? I cant make them come on at all. Any help would be great.
