I am getting air (heating & cooling ) through my top of dash

Customer Question

I am getting air (heating & cooling ) through my top of dash vents but no air through the dash and floor vents of my 2003 Ford Sport Trac. The fan and blower are working but I no longer get the sound of the interior door opening or closing. My senses are telling me I no longer have any vacuum. If this is the case how do you change the vacuum lines? If this is not the case what other issues may be involved?

Hi, I’m Ron and I can help you.
I have been in the auto repair business with my own shops since 1975 and also teach automotive repair. I am confident we can resolve your problem together. Please understand that I don't know your skill level. In most cases when you have a problem with the way the vehicle performs, specialized tooling is required to acquire computer data/information or engine testing results. We didn’t build these complicated vehicles; we just diagnose and fix them. Also understand that I can't see, smell, hear, or touch the vehicle either, so it may take a few replies to get to satisfactory results. I am also going to direct you with the fastest, easiest and most common things to check first. Please be patient and permit me to do what I do best.
I also try to give all of the information you may need, expecting a “positive rating” in return. I will also continue assisting you after you have rated me, if necessary. If there is any reason I cannot get a positive rating, please let me know why “in advance”, so I can go another direction for you. I am sorry you’re having this problem; I’ll help you through it.

The problem is the blend door is not working, located in the heater box under the dash. If it is a vacuum issue, it will be in the same place for testing/viewing.

Thanks, Ron
