Thanks for any help,
My friend has a 98 taurus with auto-type climate controls. No matter where the temperature is set, the system only delivers hot air to the passenger cabin. All the other features seem to work fine: vent/defrost/floor all seem to direct the air properly. With the a/c off, only heat is delivered. With the a/c on,the compressor kicks on, and the lines and evap get cold.
It just seems to act as though the cold/hot damper is stuck in hot. the problem occured all at once a few weeks ago.
I read one prior post which suggested checking the plugs in back of the glove box. None were dislodged.
Again, any help is appreciated.
