I have a 2011 Ford Taurus that overheats only when the AC is on. It also intermittently blows cool air when I turn the heater on. Any ideas?

Added (1). P.S. -- Coolant levels are fine.

You are low on coolant.

You think the coolant level is good, but it actually isn't.

Low on anti freeze

Have you even taken the radiator cap off yet to see if there's any coolant in the system?

More than likely, your radiator fans are not working right… One should ALWAYS be on when A/C is switched on… The other should come on as temp rises… This is assuming the fluid level is full… Is the A/C compressor running, and cycling, off and on?
