This problem started yesterday. , when you turn on A/C , you can hear Compresor activating , I thought maybe it lacked Freon , and added 33 ozs, but did not help , I am thinking that maybe it is the air blend Actuator. Is it somthing I can Do or do I have to take to dealer , If I can do it can you explain procedure ? t.Y.

A/C BLEND DOOR ACTUATOR A/C electronic blend door actuator, located on rear of evaporator housing, contains an electric reversible motor and a potentiometer. Potentiometer wiper is connected to the actuator output shaft and moves, on command from temperature control switch, with output shaft to indicate air temperature blend door position.

doesn't matter which function is selected , what temp is selected in auto or manual you get full heat. When problem was first noticed, the weather consisted of cool mornings and warm afternoons. Normally the EATC was set on 75. our feet and lower legs started getting colder and temperature would have to be adjusted to its highest setting., now no matter what setting or temperature is selected in heat or A/C you get max heat. I have not a clue where to start. Your help will be greatly appreciated.

It appears the blend door has failed. There was a bulletin for this. Unfortunately the dashboard would need to be removed for this repair. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.
