Blower switch would only work in 3 and 4 position unless I turned it back and forth rapidly then worked in all positions. Suspected dirty contacts inside. Now won't turn fan on at all. Checked fuse and even swapped it out but no help. Calling this an electrical problem since switch controls fan for heat or A/C.

This could be a switch issue but more likely would be a resistor issue. If it were me, I would just go to the blower motor and check go for power. If you don't have power, go the the resistor and check for power there. More then likely you will have it so replace the resistor. If you don't have it then the switch would be the issue.

Here is the wiring info and a guide to help do this:

Then I attached the info on how to replace the resistor if I am correct. Let us know what you find. Thanks
