Does anyone know where the vaccuum connection that comes in through the firewall connects to? My ac is blowing out of the defrost so i did some searching and found a hose just hanging under the dash. Now i cant find where to reconnect it. Does anyone know?

Thanks in advance,
JJ

 

haha no one knows?

 

what year truck do you have?? 2004+ doesn't have a vacuum system.

 

Its a 2001.

 

Check the vacuum line as it runs behind the battery. It often breaks there due to battery fumes.

 

This is not the cause. The vacuum hose i have under the dash comes from the reservoir behind the battery.
