The fan will not blow on high and the indicator button for the air conditioners will not light up when pushed.

Hello,

It sounds like you have a blower motor controller that has gone out. But to be sure here are some guides so you can do some simple tests. First check the fuses.

Please run some tests and get back to us we are interested to see what it is.

Cheers, Ken
