This is a problem with your HVAC system, it is all vacuum regulated. You will most likely have to get this fixed by a mechanic as it is extremely difficult to work on.

Vents won't blow hot or cold air. Comes from defrost and feet when you put fan on.


It's the vent actuator, it moves the baffle that changes the direction of the air flow.
Here is a video of a broken vacuum hose that creates the same problem.

It could also be a failed actuator.

I have a 2009 Kenworth W900. The ac/heater started only coming out the defrost. Now hardly any air comes out of any vents even though fan running. Cause? Solution?


The mechanism that controls the louvres for directing air flow is fubar. PIA because it is behind the dashboard.

I have a 93 4runner v6 manual. I went to turn the heater on the other day and no air was coming out of it but when I started driving down the freeway air started coming through the vents. When I stop


sounds like your fan is either jamned, burnt out or even frozen, you might be lucky and find its just a blown fuse, you'll need to check your fuses box then start investigating if the fan turns freely or not

if you put the air on recirc you might be able to stop cold air blowing in when you are travelling. if you are waiting for a garage to sort out the fault then get a fan powered by the cigarette lighter, air moving over the window should at least keep mist clear even if it doesnt defrost it

AC/Defroster issue


On most vehicles the AC comes on when the defrost is on to keep AC compressor/clutch from seizing up from non use during winter months.

AC will not come out the dash vents all the time. Can lower the fan speed really low and they will sometimes switch back to the dash. All air is coming out the defrost vent.

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.
