So i was installing a radio in my mazda tribute.. And since the radio install i have had a vacuum leak in my air.. How i have determined it to be a vacuum leak is that when im not on the gas it blows fine after giving it some gas it quits blowing from the vents and comes out the defrost.. Im looking for some pointers maybe a known issue or a known vacuum line behind the radio or something..

 

ive read somewhere that they have a faulty something behind the temperature control.

 

I'm not sure with your model. Used to be vacuum was used to control airflow through vents, defrost ect. New cars default to defroster vents if there is an issue. I would think an 06 would be electric, again i am not sure. Best thing is to trace the vacuum line down.

 

while changing the radio i dont remember a vacuum line there just alot of plugs and stuff.. But just from the research it sounds like a vacuum leak since it works fine when not on the gas

 

Look under the hood for any vacuum line going through the firewall (if there is any).

 

ok thanks for info.. I was curious if anyone else has had this same issue leak in vacuum line
