Hey guys, i turned the A/C on yesterday on my way home from work, but i coulndt get the air to blow through my dash vents, it only comes out in the defroster holes no matter where i put the selecter switch.. any ideas?

 

vacuum problem? not sure on our trucks, but in most cars the selector is powered by vacuum.

 

Check the Vacuum Lines under the hood. All it takes is a small leak.

 

Yep,I bet vacuum leak too.

 

Ive seen a few drop down the backside of the turbo and melt

 

Two weeks ago I had the same problem tore the whole dash apart trying to find the problem turned out to be a vacuum hose got pulled loose . Spent 2 hours on a 15 second fix

 

sure as $hit thats what it was... one of my rubber boots that connects to a T fell off..that was my vacuum leak. 10 second fix. I also secured the vacuum line on the back of the hood weatherstrip with zipties. thanks for the help!!

 

mine does the same thing but i cant seem to find mine
