'96 Astro. No air from vents.

Hello all. My 96 Astro van is not blowing anything out of the dashboard vents. It sounded like it was blowing full blast but no air at all was coming out. After some google searches I found out about the vacuum hose. After tracing the hose I realized it was severed in half. I was able to get a new hose connected but now I am getting nothing at all when turning on the air. It doesn't sound like it's doing anything (not blowing at all). Everything looks exactly the same as it did before the "repair" with the exception of the new hose now running over the air cleaner cover.
I checked all fuses that sounded like they could be related to the problem but all of them looked fine.
Also, I am still getting rear a/c and heat, just nothing up front.
Hopefully someone can point me in the right direction or at least let me know some things I can check.
If pics would help you help me let me know and I'll run out and take some.

Check to make sure you didn't disturb any of the plugs to the blower or blower resister. Test all the fuses with a test light.

I'll pick up a test light from the store and go digging in the morning. Thanks for the info.

If all the fuses check out, test for power and ground arriving at the blower motor.

Alright, all fuses checked out. I tried using the same test light on the blower motor plug but it didn't read 12v like the fuses, instead only the "Continuity" light came on. This light has me confused, when I used it on the good fuses it never came on so I'm not sure if it means it has continuity or it lacks continuity. The manual that came with it doesn't say which it is. Attempted using a multimeter on the same plug but kept getting bad readings with parts of the numbers missing, so I'm convinced the multimeter is FUBAR. Should I just take the motor cover off and replace the motor? I don't think the plug/wiring is bad since it worked fine before replacing the hose. This really has me stumped and I don't have money to take it to the shop after fixing my brothers car for $400 and $450 for a fuel pump in my car.
Any advice would be greatly appreciated.

Make sure yopu check the 30 amp Maxi fuse in the underhood box. If that is good test for power at the red wire of the blower resister. If that wire has power and the lower motor does not with the key on, the resister is bad.

Ok the motor is definitely working. I took some compressed air and blew out the plug and connector. It is now working again but there is still only a small amount of air making it out of the dashboard (more than there was originally.) Its just enough to be able to feel it with my hand 1" from the vent, it is on max speed also. Is there any other hoses that could have been damaged, the one that I replaced it supposed to have been a common problem with these vans just wondering if there are any I'm not aware of.
Also, thanks for the help with the motor. Feel kind of bad wasting your time when the problem was apparently a dirty plug/connector.

It's probably a bad blower motor.
