OK, i've read other posts and it sounds like resistor problem . Where is this located on '93, and part# ? thanks for any help on this

I don't recall the '93 specifically, but blower resistors are always located in the blower case so the airflow will keep them cool. Look for something with a sort of diamond shaped base, two screws holding it in and a connector with 4 to 5 wires coming out of it.
