'99 Trans Am A/C Not Blowing Hard Enough
Hey everyone,
I finally got my A/C blowing cold yesterday afternoon on my off day from work.
I replaced everything when it came down to the air conditioning components: condenser, A/C accumulator, discharge line and the line that goes behind the compressor to the condenser (don't remember the name of it but you get the point).
So yesterday I put in the freon (R-134A) and it was finally blowing cold. I noticed when I put the HVAC **** to "A/C" and put it to the "III" and it barely hits my face. "I" and "II" do not work, meaning the A/C does not hit me at all; I only use now 'MAX A/C" and set the **** to "III." it makes a little bit of a difference but not much.
I've only owned the car for a period of two months and I don't know how long the car has went without air conditioning. I was reading earlier today that the blower could not be blowing at it's full capacity; or it could be the blower on it's last legs or there is some debris that is just mainly stuck in the blower.
If it is the blower, where is the location of it and how can it be replaced IF the blower is defective? Also, I was also reading that blower is on the passenger side underneath the dashboard can get clogged with full of debris.
Any ideas, suggestions or recommendations are welcomed. (I live in Las Vegas and it's already in the 100s and we're barely in June; trying to tackle this problem before I burn to death lol)

You might also check your other vents and make sure that the vacuum-powered vent actuators aren't bleeding pressure off to other ports, instead of concentrating the flow to the ones you have selected.
This is a good thread that shows how to remove the blower: https://ls1tech.com/forums/general-m...cares-lol.html

It could be the blower, but I'd chase down the vacuum thing first. Given that the force was fine before the line break, I'd think that is suspect.
I'd use a piece of paper or a tissue to test for flow at the other vents. If anything is off, I'd then invest in a MightyVac to test the vacuum lines to see where you are leaking/loosing pressure.

You have the defrosters, the dash vents, and floor vents.

When I took off the blower (noticed it was a new one when I bought the car) it had a couple of leaves in the fan blades; I took them off and put it back on and still did the same thing, I put on the original blower off a V6 93-97 Firebird and blew better but it still didn't make that much a huge difference. A couple of people told me that it could be the cabin air filter (from what I've read all 4th Gen F-Bodys do not have a cabin air filter). Before I put on the older blower I reached my hand inside the hole and felt leaves at the top and some other debris but nothing felt like it was clogged on. Do you have a A/C vacuum diagram I can use?

I would expect there is one on the Factory Service Manuals by Helm, but that's copyrighted - so can't share here. (I'd highly recommend picking them up, regardless.)
You should be able to test all of the lines at the control panel. All should hold a vacuum. With a MightyVac pump, you could even use the tool to actuate the diverters to confirm if you have a vacuum supply to the system, or not.

Your compressor could be leaking too. My original compressor eventually started leaking around the casing seal. Wouldn't hold a charge for more than a few days. You would be able to feel fluid on the bottom of the compressor.
