How do the climate control levers work on a 1965 ford mustang?
pull the three levers down and the fan switch to the right for full heat and defrost.. .
Left is air for heater, down for on...Center is temp, up for cold, right is defrost, down for on.
There is also a knob under the dash for fresh air for driver, and on passenger side, open heater door for fresh air for passenger..
you can find this info in the owners manual and copies of it on ebay..
