I verified that I have a couple vacuum lines open. One is a thin hard line 1/8" diameter and the other one is soft about 1/4" diameter. The thin one is very brittle and the larger one is mushy and deteriorated. This was good information and I believe it will assist me in finding the problem and hopefully fixing it. Thank you.

On my 2005 Ford Taurus the air conditioning is coming out the defrost vents.


There is a flapper or trap door in the dash board that diverts air flow to various vents, defrost, floor, face, etc. If that stops working it will get stuck in the default position which is usually the defrost vents.

If you have a vacuum operated system you can check the vacuum hose for the system in the engine compartment for integrity. If that is ok then you have to get to the vacuum switch in the dashboard and probably replace it due to leaking vacuum - labor intensive and not cheap.

Any time the dashboard has to be removed you are in trouble money wise.

2005 Silverado 2500HD 4WD - It appears that the pneumatic valve controlling the directional air flow from my heater/AC is getting stuck. When I switch the fan to front window defrost then back to...


The default configuration when all vacuum fails is to defrost vents. Most likely your vacuum supply to the switch is weak. Check the connection of the supply line to the intake manifold for damage. If no problem there, trace it to the switch on the control panel. If there is an accumulator, make sure it isn't leaking and is storing vacuum. If all this is good, look at any other vacuum lines connected to the intake manifold that may be leaking and possibly reducing the vacuum supply to the HVAC control line. Let me know if you have more questions.

91 ciera only does defrost, no vents or AC


i believe this is a vacuum operated system. if there is a problem with the vacuum supply to the control unit, it will automatically default to defrost. i would start by checking the vacuum source lines. good luck!

Air condition vents on dash are not blowing any air, only the defrost vents on top of dash are blowing, any ideas


It sounds like the flap that controls air flow is stuck. It is controlled by vacuum. The vacuum line could be leaking, the line could be off, or the vacuum actuator could be faulty. Hope this helped.

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.
