when i turn on my air or heat there isnt anything coming out of my vents....only out of the front windshield defroster vent.....what in the world could this be? thanks...Sean Lucas

Vac. leak, check under your battery.

i dont seem to have any vacuum leaks what else could be my problem??? where else could there possibly be a vacuum leak?

Sean...look deeper! Normally the vacuum line going to the "ball" that is mounted under the battery is the cause of this... 8)

hey thanks for the tips my TGP does the same thing but it only comes out the defrost vent and the floor vents.
