Anyone know what the problem would be?. The A/C works, but it blows out of all vents(floor, dash and defrost) when on... however, it does this no matter what position you have it in(Just top vents, defrost, just floor vents... all of them)! I don't know anything about A/C and don't have any idea what the cost for something like this is.
Thanks for any advice...

More vehicle info would help. Year, make and model, engine option.

The problem may be the mode door switching isn't operative. Some are electrically controlled, some by vacuum switching.

Help us help you...

Sorry... 1998 Pontiac Transport Van... V6 Automatic 3.4L.

Verify all the fuses under hood and in the dash are good. If the fuses are OK, the problem is likely the A/C controller (the A/C control head in the dash).

Thanks!

I have checked the fuses under the hood(all are ok)... where are the rest of my fuses? I don't see any under the dash... Thanks

TranSport has a fuse and relay location on the right side of the dash. Open the RF door and on the side of the dash is a small panel. Fuse may be related but the more common concern is the controller. Let us know...

Gosh CaptainRich you're good... it's the controller head... but I did have some fuses to replace as well. Thanks so much for your help.
