My A/C fan does not run at all.
I have an 01 grand with auto temp control. I thought the fan motor went out so I replaced it. I checked the fuses and relays all were good. When I drive with the vent on I can feel the cool air coming out of the vents slightly but nothing happens when I try and adjust fan speed. What should I do
It's quite possible that your old fan motor burned out the switch in your dash. I've seen several that melted the connection on the back of the switch (you have to pull the controls out to see it). There is also a resistor block that can fail but usually, you will at least have High Speed and nothing else.
