Jay :

Hello and thank you for using JustAnswer.com

Jay :

Automatic air system correct?

Jay :

The heat only works if you put it to 85, if you put it lower it blows cold correct?

Customer:

Yes, That's correct, I'm not sure about the AC, I'll try to run it and find out now

Customer:

I'm not sure about the AC - it blows cold, but not sure if it mixes heat or not as outside temp is about 78* and it's hard to tell

Jay :

Most of the time when that happens and the head doesn't work properly, it's due to the sun load sensor.

Jay :

How handy are you?

Customer:

Jay :

Ok, cook
