1) Does the motor not kick in (fan) or
2) Does the selector not work?

It dont do anything..i cant hear a sound
thinking maybe its the fan???? or the switch to turn on ????
ANY IDEAS??? would appreciate

I will look in the service manual tonight when I get home. It will have to be something that would be common with both. Could be a vent door that is controlled automatically could be jammed. I would think that even if the blower motor did not work you would still feel a little cold air or heat.

there is temp air duct with a door that will let in outside air , ac , heat. it is controlled by vacuum. it is in the dash, or under the dash.
