I am having the same problem, it is been a week and half, heat went out, now it is blowing cold air and temp is going hot and normal, but once a day and when idle for 30 minutes it doesnt go hot
Check your coolant level. Typically you will get cold air when you are low on coolant.
Ok I will check it
what kind of coolant should i buy
I think it is yellow for fords, go to the auto parts store and tell them what you have and they will give you the right kind. It should be mixed 50/50 coolant to distilled water. you can buy it this way or mix it yourself.
