For about a year now I get no floor circulation.It actually pumps out the windshield vents though not forcefully.Any ideas on where to sniff around?Thanks in advance.

 

done any stereo work lately ?..you might have a vac leak in the dash some where......

 

Excately what it is, vacuum leak. Had it happen to me once. Check lines real close, even under the hood. Then again it could be a plugged vacuum line. Hope this helps.

 

this problem with my son's ranger. the dealership kept checking all the vacume lines to no avail. they finally had to replace a vacume control box and the truck has been fine since then. so if you don't find a problem with your lines, check out the box.

 

Thank you all for the tips.I'll let you know.

 

its the blend air door not operating properly. a couple of areas to look is at the blend door vaccuum line connection, it may have slipped of or somebody may have accidently kicked it. if not, then it may be a leaky vaccum line. try this. accelerate really hard, while selecting the vent. then decelerate and let the motor slow the truck down. if it changes, then a vaccum leak is suspected. if not then the blend air door is not seeing vaccum signal.

 

So I managed to lose one of the springs in the EATC. I know, I know. Any idea where to get one or the specs on it? Thanks.

 

Well, you aren't going to get much help reopening an 8 year old dead thread in the V-6 Engine forum - post in the HVAC forum and provide vehicle details.
