GtipGary Posted January 25, 2008 Report Share Posted January 25, 2008 So for those who dont know i recently had to change the transmission in my car... that was a lot of fun ... Anyways after i did the swap i notice that my heat only blows out of the top... no matter what setting i put it on it only blows out of the top. Could this have something to do with the transmission swap (maybe i disconnected something). Or is it a problem thats in the dash??? Quote Link to comment Share on other sites More sharing options...
1990lumina Posted January 25, 2008 Report Share Posted January 25, 2008 Vacuum leak...probably pulled a vacuum line off somewhere or broke a T connection. Check down by the vacuum ball first. Quote Link to comment Share on other sites More sharing options...
GtipGary Posted January 25, 2008 Author Report Share Posted January 25, 2008 check under the hood??? I thought all of the vacuum lines for the heat and a/c where under the glove box. Quote Link to comment Share on other sites More sharing options...

charged 3.1 Posted January 25, 2008 Report Share Posted January 25, 2008 Check over by the master cyl. Theres a little black plastic vacuum line that runs into the car for the heater controls. I did the same thing when i did my transmission. Quote Link to comment Share on other sites More sharing options...
