Well i got my a/c working and it works awesome nice and cold!! well i never use the dash vents when iam using the heat i usually use defrost and feet well i cannot get the dohicky to go to the mid vents or to the floor its like its stuck or something what should i do

this is on my 2001 ranger 4.0sohc

 

Remove the A/C control unit and check the vent wires in the back if you have them cant remember. The control the vent flap.

 

 

You probably lost the vacuum supply to the HVAC controls and the default position is to the defroster ducts.

Check the hoses to the vacuum reservoir underneath the air filter box. It has one vac line from the engine and another to the HVAC plenum on the firewall. Sometimes these get unplugged during underhood servicing or can get burned against the PS exhaust manifold.

 

thanks man will check these asap...maybe i bumped something under the hood replacing the hoses

 

blend door

 

checked these and all hoses appear to be fine..any thing else to check?

 

The vac reservoir itself and the vacuum harness and hoses under the dash.

 

checked everything and wiggled stuff and now the only setting that dosent work is the dash vents..it goes to defrost to floor to defrosr and floor but will not go to the dash vents

 

are your vents blocked?

 

no..all of them are open it just stays on defrost when i switch it to the dash vents

 

If that's the case, then I think you need to look at the 3 vacuum servos under the dash. Make sure that they all move as you cycle through all of the possible HVAC modes.

 

i got it it wound up being hose next to the round thing it was unhooked before i started anything with the a/c system and i hooked it up and thats when i noticed that the dohicky wasnt working its working now in all modes with it unhooked like it originally was before i touched it.....its all good now
