If you truck has the Computer Climate Controls, I need you to help me verify something. When you switch it to defrost or heat, and attempt to change the airflow to "recirculate", does it "take' the command and then a few seconds later kick it out? And no matter how many times you try it, it will not lock into recirc no matter what you do?

Also, if you crank it up to 78 degrees, and set both dials to AUTO, it still turns the AC on?

thanks.

 

both of mine do the same thing. you cant run recirculate when you have it on defrost for sure. but i dont think that i have ever put mine on heat. i just keep it on feet and face and crank the temp **** to heat and if the a/c light comes on i just turn it off. i dont put the selector switch on the right to AUTO mostly because it lets the air in from the outside and blows it right in my face, which i cant stand. the fan on auto will only effect fan speed.
