There should be a little canaster insid the dash maybe attach to the duct work it changes the position of the door if not it may be the control slide that you move to change the position of the heats function

Does the Erg vacuum solenoid cause the ac switching from vents to defrost


the ERG shouldn't have anything to do with what vents the AC comes out of, rather the dash switch that exists for changing from defrost to main vents to floor vents controls what vents are used.

Defrorstores stay on ,try to change to floor, ac, heat vent ,deforstores still on 1995 thunderbird lx blower motor works great.


Some cars use vacuum from the engine to open and close the doors that direct the air to different positions. It is possible that the vacuum line to the controls is cracked or disconnected.

No matter what setting you have the air or heat on, it still comes out all the settings(vents, defrost and floor vents) all blow at same time in my 2003 chevy impala


sounds like you have a bad blend door motor that is stuck in the middle allowing for all vents to blow air... locate the motor under the dash and remove it. manually move the lever and see if it changes the flow.. check for power at that motor to make sure your getting the signal from the dash then you'll have found your problem....

A/C will only blow through defrost vents


Common question on this site. On late model cars, the vents are controlled by blend door motors. Small electric motors open and close doors to direct air flow.
Chances are you have a blend door that is stuck or a failed motor.
The default position is the defrost to make sure the windshield is always clear.
Someone will need to look behind the dash to see if all of the doors will move on demand.

You have two control motors under there one control the bunk for hot and cold. The other control front for hot and cold. Defrost vent and front vent is in the dash.

AC/Heat/Defrost inoperable


Chanses are its either the blend door motor quit working or the controls ( temp., selector, blower) in dash are bad, my 95 did the same thing i chg. the blend door motor thinking it was that, but it turned out to be the controls in the dash, 5 minutes work and 140.00 later it was fixed.

Heating / air conditioning control stuck to front defrost vents


There is a vacuum leak under the hood. Find the vacuum line on the passenger side where it comes through the firewall and follow it to the engine. You system needs vacuum to operate and without it the default setting is on defrost for safety reasons.

Heater


Pull the AC control in the dash and verify that there is vacuum going to it, all the different air diversion doors are operated by seperate vacuum motors controlled by the ac control head in the dash, as you switch it it sends vacuum to the correct location to work that door for the desired air outlet, dash, floor etc..
