so im getting the defrost vent and foot vent no center vent....ive checked the vac ball and all the lines an they are good, i took the front bumper off a few weeks ago and it worked fine till that point....after i put it back on it has not worked since, if i un plug the ball it has air pressure in it still so its not cracked ....not sure what it is any ideas anyone??

 

Well right behind the front bumper on the passenger side, there is a part of the vacuum system, when you removed the front bumper you probably left it off, or put it on wrong.

 

i wrote in the title it wasnt the vac ball....hahah

 

Could have a lily leak Bro. Suspicious.

 

Had the same problem.... no center vent with AC. Found a small hole (vacuum leak) near the battery tray.

 

yea im still not finding it...i replaced the line next to the batt with a different one, the ball seems to be holding pressure when i pull the line too....what do you guys suggest ? just spraying till i find the leak?

 

at this point id agree on fogging the system to see if/where there is a leak.

 

Try this... cuts way down on vacuum lines and potential problems. Worth it while you're there.... I painted the tray after the pics :-)

 

^ so your saying just run a vac line straight to the ball ?

 

I just eliminated the lines running forward and started with the ones at the firewall.

 

ran a vac line right to the line going thru the firewall same thing.....i can hear the vent make like a click noise and thats it....maybe its hung up ? any ideas guys?
