Hello Kevin, sorry to hear you are having heat issues. Let me ask a few questions to get an idea of what is happening. do you lose airflow? or are you still getting good air flow just no hot air?

Can I get someone that will help me???
Automotive Expert

No I don't lose airflow

ok, do you only get heat while MOVING or just revving the [engine](/topics-engine-ford/) in general? this model should still use a vacuum operated control valve on the engine, passenger side i think. you could have a poor vacuum issue that is why you get flow when revving the engine. i would check that.

Do u reply here or text message?Revenge the engine in genneralThe heater control valve is always open unless u have ac on correct?

I am replying here on our chat, I dont know how you are accessing it, I know the site has a text feature as well but im on a desktop, so how you receive it can be a few ways. then yes you have a heater control valve/vacuum issue . you will need to check the vacuum line to it. I believe you only have heat when you select heat. i will have to check on that. it will only get vacuum when heat is selected. I could be backwards on that, it may get vacuum all the time unless you select ac you might be right on that. been a min since I worked on one of these. this model may also have a vacuum operated blend door,. so check the vacuum lines from the engine to the firewall. passenger side. but with your issue, and symptoms, it is definitely sounding like a vacuum issue to me.
