I went to turn on my A/C today, and the blower didn't come on. I waited a few seconds, and the blower slowly started to spin up. After about 30 seconds it was working just fine. Could the blower motor be going out, or is there a problem in the HAVC controls? What do you guys think?

Ok, I have an update. It's not the blower motor. I had a chance today to take a look at the ac, and I noticed the the blower comes on and works just fine. The problem is that the ac only blows at your feet. After about a minute it slowly starts blowing out of the vents. So what would be causing this?

vac lines for the selector has a leak somewear. The mode door will go to defrost as a default if there is a leak

Ok, how do you check for a leak?

You need to visually check the vac line coming from the rear of the A/C controls to the Mode door. Someone esle may know a short cut. It's kinda a pain.

Great, I know what I'm doing in the morning. Now that I think of it, a vacuum leak makes since. I noticed a couple days ago whenever I would accelerate kinda hard, say getting on I4 the ac would stop blowing for a few seconds. :/

The computer in the car turns the A/C off when you accel hard to give you more power. May not be related to you vacumme leak.

I skimmed through the link I posted and it looks like they has problems witha line that connects to the manifold. If you can't find it there the leak may be in the dash. The line may of cracked or have a small hole and thats why is starts to work after a min.

I was browsing through the link too, and that seemed to be the problem most of the time. I guess I'll start there.

I just thought about it, you have an LT1 so it may not look like the pics I added but may be in the same general location

The little 2-way check valve in the 3rd pic was broken. $4 at Advance, and she's working again! Thanks for the help man!
