This car has the automatic climate control (temperature control)system in it. on all of the settings--A/C, vent, Max A/C, heater, defrost it only blows hot air and the temperature of the air can not be controlled. Changing the temperature setting by pushing the red or blue "rocker switch" on the top left corner doesn't seem to make a difference. The A/C compresser & other parts in the encine compartment, seem to get cold with condensation on them--but NO cold air comes into the passanger compartment. The fan is working ok, the fan speed control works ok & the air comes out of the appropiate places, IOW the floor vents, the dash vents, the defrost vents, etc. what needs to be done to this POC?
The hot/cold switch is probably bad.you have a blend door box that opens to let the cold air in and closes to let the hot air in.From what you are saying this part is no responding to the switch movement.Make sure power is at the switch and power should go through the switch when put on cold air this moves the blend door.Some times the blend door goes bad and has to be replaced its under the dash on the right side.

I found the ATC System self diagnostic procedure (or EATC) & preformed it on the car. It came back with a code of 024 (Blend Door Actuator Malfunction) 1st--where is the blend door actuator & how do you fix or replace it? Is it a "fixable" part & what might be wrong with it? electrical or vacum?
The hot/cold switch seems to be OK.
After running the diagnostic, I found a piston type of assembly on the right side, under the dash board and glove box, near the side kick panel & pushed the piston rod in. Your suggestion that it was under the dash & on the right side was the key. The Blend door moved its position & cold air came out thru the dashboard vents. since then the A/C has been pumping cold air into the car, whenever it is restarted--3 times now. This may be a temporary fix, don't know.
Any suggestions about this actuator would be appreciated
The vent, floor, defrost air diverter does not work. This seems to happen when the car is changing power settings which leeds me to believe it is the vacuum system.
