I have a 2012 focus with automatic climate control that had the radiator replaced and AC condenser replaced, as well as new coolant and the ac recharged.
When running the AC with a temperature setting, like 69 degrees (instead of high or low), the AC will run nice and cool, but will randomly go from cold to hot (not warm air like a compressor turn off, but hot like the heat was turned on). If I turn the AC down to Low instead of a temperature, the heat turns off and the AC continues to blow cool. If I turn it back immediately to a degree, the heat comes back on.
The issue happens intermittently.
I was wondering what could be causing this?
