Blower fan doesn't blow hard.
I have a 2000 Cherokee. My ac is cold but doesn't blow hard. I've replaced the blower with a used one but I believe it works fine. I hooked it up before installing it and it appeared fine. My actuator is fine the air moves to different locations properly. I don't seem to have any blockage in the duct. I do have the fan straight wired to a toggle switch because it stopped working and I replaced the three switches in the dash and it didn't help and my fan still didn't work this is why I put à toggle switch in. At this point I'm stumped any help would be appreciated

You probably just needed a new Resistor Block.
Here's a schematic that shows the Resistor Block.

OK ty for responding. Is the resistor block located behind the glove compartment, in the duct, slightly to the left of the fresh air/recirculation air flap? If so I took mine out was all rusty so I replaced it with a used one (I'm on a very tight budget )that was good and clean looking no rust. And it didn't help. If it's something in someplace totallydifferent where is it plz ty

I've had insulation from under the dash block the core. Mine was so bad, it covered the blower wheel as well as blocking the core. It's very good now.

Where did you get this used resistor block?
How do you know it was any good?
