Thanks for your question. Sorry you're having car problems. If I go off line, just leave a message and I'll be right back. DO NOT leave feedback yet. You either have a vacuum leak at the vacuum motor, or the blend door inside the heater box is not working right. See attachment too. Thanks, Ron

Please note: not every answer I give you is something you were hoping to hear, even though it is true, such as; (it’s more expensive than you wanted to spend, or you will need to have a professional repair shop do the diagnostics and /or repairs due to complexity reasons).

how much would that cost to repair at a ford dealer??
It really depends on what they find wrong, but the worse case scenario would be about $400.00. Ron
Customer: replied 4 years ago.
could it still be under warranty since the vehicle has only 14,000 miles on it.
That's a good possibility and worth checking out with your dealer. Thanks again, Ron
