Maintenance/Repairs

Greetings. I have a 2003 Chevy Malibu LS. The fan used to adjust the interior air flow is not behaving well. It started to not work in the 1-4 position, only the OFF and 5 positions worked. Essentially, positions 1-4 did nothing and position 5 acted as position 5 should; really high fan speeds. It did not matter if it was on the heat or A/C, and selecting different vents made no difference either. After a few minutes of being either OFF or on 5, I can use any of the 1-4 positions as usual. I saw something similar to this on a Grand Prix I owned, and the remedy for that was to replace the blower motor resistor. I did that, and not only did the resistor not look damaged, the problem still persisted. I checked the fuses, not knowing which one exactly was controlling this function, but they all looked fine. I am thinking about replacing the blower motor, but before I do that I want to see what you or anyone else thinks is a good plan of action, or if replacing the blower motor is a good next step. Thank you, in advance, for your help.
