Re: '97 Grand Am Electrical Gremlins....

Could it be a ground ? Follow negative battery cable, and add 10 guage wire from main ground to radiator support, and another to firewall, and a
third to fender that has heater blower [ fiberglass box ] grounded to it. Be sure all metal connections are clean, paint over for corrossion protection. Good grounds prolong the life of electronic components. On frame cars, I like to add a Ford Starter cable from engine block to frame rail.
