HI there,

Do you have a test light or a volt meter so we can do some testing?

Ok

Well, start by checking the blower fuse in the engine compartment fuse box. If the blower is getting power, it will get it from this fuse. The switch on the dash is used to ground the fan, this makes the fan turn on with the resistor in between to slow it down on the lower settings. Without a meter it's difficult to tell which all is bad.

But if the fuse is blown, that will stop the whole thing from working. Normally the resistor will prevent the fan from working at any speed but full.

Also check the A/con fuse in the fuse box inside the car. If it's bad, then the relay won't work and the fan won't kick on.

Please check these and let me know.
