First of all, the old blower motor I had in my car kept on blowing fuses everytime I would turn it on. So I took the car apart to get to the blower. Then made sure the wires were hooked up correctly and tested it. It still did not work and it blow another fuse.

So I decided to buy a new motor. I installed the new one and tested it. It worked fine and didnt blow any fuses. Then when i put everything back together, I tested it and I felt no air coming through any vents. I did hear noises when I pushed the buttons, but I dont know what they are.

Could the blower be in backwards?
Could there be something clogging the vents?

Thanks
