Can someone tell me what to look for here.
My fan speed selector only works on High speed, and only works if I move the mode selecter all the way to Defrost and then back to max AC. The other speeds for the fan Don't work no matter where the mode selector is. Last year the high speed fan would not work this year it's the other fan speeds. Any Ideas on where to look would sure be appreciated

There should be a "block" with a few screws holding it down on top of the heater/AC box under the hood.
It'll have a few wires going to it[not the blower motor].
You want to pull that block out and check the coils and connections.

and, if it is not the resistor block, check the relay

Where is the relay located? Thanks for the help
Dale :yup:

on the hvac box under the hood close to the resistor block
