Very unlikely a vaccumm line gets plugged.
why do you think that...what is going on that makes you think its plugged?

And what line are you talking about most of those cars have no vac. line to the heater..they are electrically operated servos.

Ac and heat air flow stuck in defrost postion up top .


The hvac blend doors are vacuum actuated. It takes vacuum from the intake manifold via a line that goes through the firewall just right (passenger side) of center. Open the hood and look for a disconnected or broken line in that area and repair as needed. The default position for the blend doors is the defrost position. When vacuum is lost you'll experience what you've described.

it's not the duct work . there is a problem with your vaccum lines running to the motor. what's happing is the vaccum line is not getting enough suction to make the flap change that's why you hear it but don't feel it. check the vaccum lines for the a/c

NO HEAT ON FLOOR, I INSTALLED A NEW ACTUATOR BUT STILL NO AIR ON FLOOR SETTING , I HAVE THE SAME PROBLEM WITH MY 99 S-10. IS THERE A PROBLEM IN THE SWITCH WHICH CONTROLS THE DIFFERENT AREAS IN WHICH YOU...


The floor usally has a vaccum servo,so check it to see if the servo is moving.Pull the ac/heater control from dash,and remove the vaccum plug.Spray some silicone(silicone spray only)in the vaccum lines(plug)and the receptical for the plug.Do this while it is on,and engine running,this will unstick the vaccum switch if it is stuck.Also before starting this,check for vaccum at this vaccum switch.If there is no vaccum,go under hood and follow the vaccum comming out of firewall,and find a vaccum reservoir,or a vaccum check valve,and check them to see if they are damaged or not connected.I hope this helps,if you need more help let me know.

Heat and air only come out defrost on windsheild not vent or floor


The air handlers on jeep are powered by engine vaccum and when a loss of vaccum happens the air is defaulted to defrost,so under the hood on passenger side is a 1/8 small black plastic line should be plugged into a bigger rubber or plastic vaccum line sometimes after a few years the rubber boots the use get soft and washing the engine or just moving things around can unhook the small line

Heat fan not working in 2001 ford escape


GM uses vaccum to operate the blend doors on their heating and air conditioning systems. There is either a cracked hard plastic line or a cracked, unplugged vaccum line somewhere. If you have done any work to the vehicle latelt I would start by looking there first.

Blower works and no heat or air come out


I think you are on the right track with the blend door. Most of these are either a vaccume survo or a actuator run by a small electric motor. Open the glove box and remove the lid look to see which one have if it is a vaccume type check for vaccume leaks in the engine compartment.And to check the survo unplug the line and apply vaccume and watch for the rod to move and it should not bleed down till you release the vaccume. If it is the actuator, check for power at the plug, if none found check the fuses. If you have power replace the actuator. Hopes this helpes

1990 Chevy Corsica heat issue


I think your on the right track with the vaccum/heater issue. Its not the core if its just not blowing out of the right vents. Find the plunger on the side of the hvac box that controls the selector door by squeezing the plunger by hand to see if it changes what vent it blows out of. If it does change when you do this, its a vaccum issue between the plunger and the vaccum bar. Trace the vac line from the plunger back to the bar, I bet you find your problem.
