Which speed? Makes a difference. Works in only one selection, same speed in all selections, or what? Whats been replaced so far? What led up to the problem? Were you installing something that had you pulling the center console out to begin with? Do you hear the fan motor change speed but still feel only the same amount of air? Is the issue actually air movement or lack of cooling....assuming in Arizona you don't ever use the heater. Provide some detail in explaining the symptom in some detail and I may be able to help you isolate the issue.
Do you know how to use a multimeter to check voltage and resistance? Do you have one you can use if the answer is yes?
Say hello to the London Bridge for me. Been there....done that back in 1990 shortly after it arrived. I lived in SD,CA then. I remember the guy thinking he had bought tower bridge in London and was shocked at what he had purchased when it arrived...or that is how the story was told.
