Front air vents are not working. Defrost only works.

So I crank up my 2000 Expo this morning and turn the defrost on to allow my front windshield to defrost. I tried to change the air flow by selecting any of the other air flows....nothing happen the air continued to only blow out of the defrost and the rear vents......I've heard it could be vacuum hoses, I don't believe its my blower motor since the heat still blows through the defrost and rear vents.....I had to go to work so first I will try the fuses but I doubt it will be that easy

Please give your personal experience or trials with this issue.


Thanks EXPLORERFORUM!

Welcome to this forum! I've moved your thread into the A/C & heater section. It sounds like a vacuum leak from what you're describing.
