why does my ford focus over heat when i turn the ac on
If you have the defroster on, the ac comes on automatically.
There are a number of reasons you can turn your AC or heat on and nothing will happen. The system may not be hooked up.
Your a/c system may be freezing up and you need to have the system checked.........
You have a blocked radiator.
the ac belt or the compressor bearings are going bad
turn on your ac and see if it comes on then
Check the blend door motor/mechanics or heater control head
The most likely reason is your AC system needs recharged.
That is normal.
Yes just as long as you do not turn on the a/c..............
when the AC is on it puts more stress on the engine cause the engine has to now turn the compressor. which in turn adds more heat to the engine.
