OK guys needing some help. I have a '90 NA z32. A few months ago my a/c cut out. Since I have changed the blower motor and Checked all fuses, I also swapped resistors but that was while my old blower motor was in ( process of elimination). What else could be the problem. Blower does not turn on but I can feel the cold air coming through the vents when driving and econ mod are on. Also the Heater works as well.
