Yeah, are there any pictures of this blend door, motors or actuators or part numbers that I could look at or search the web for?

The car is still blowing cold air but it is just not coming out of the vents when it acts up. You can put your hand to a vent and still feel some cold air escaping but that is it. You can hear it though, almost like the blower is blowing air hard but the air has no where to go because it's hitting a wall or something.

I'll check the freon, but I don't think that is going to be the problem because it doesn't stop coming out on one side. When it stops blowing it just stops coming out of all the vents if I remember correctly an no matter which mode you select, it normally doesn't help as it is like the air is just being blocked in the system!

Thanks for the diagram blackarrow!!

Out of those parts listed, which one do you think my problem would be caused by or should I try first? As mentioned before, when it does it, it still blows cold air, but nothing comes out, almost like the air is blocked!

I see a cheap gm blend door for like 62.00 on ebay compared to the new cost of 153.

If the seated man symbol on the climate control is blinking, check for codes first: http://www.grandprix.net/forum/ubbthreads.php?ubb=showflat&Number=107192#Post107192

Check your PMs.

I was wondering same thing as snowcrash, but I don't have the digital climate setup. Which part is possible the cause?
Mine gets nice and cold, but the left three vents barely push air at any of the level settings.

Thanks
