If you have a 2 stage furnace (hi fire & lo fire) then the blower will run on lo speed in lo fire & hi speed in hi fire and in AC mode. If it`s a single stage furnace lo speed for heat and hi speed for cooling.

2004 Chevy express van, heater has no high speed, at one time the blower stayed on even when the ignoton was turned off therefor draining the battery,
Why does the heat blower only work on low and medium but not on high?
the blower resistor controls the fan speeds
What size electric motor do you need to run an air compressor I have a furnace blower motor. Would that be suitable or do I need a heavier duty one?
It would all depend on the size of the compressor. If it's a small one(like for an airbrush gun) it might just work, but if it's a compressor to power impact wrenches or similar it'd probably not work.
Why does the blower fan only work on high speed?
The blower motor resistor module is ruined and need replacement. It can be found from below and behind the glove box. Tt may be hard to see, follow the wires to connection that is mounted to the blower unit by two small hex-head screws. I removed the glove box so I could access it easier than trying to go from the bottom in a confined position.
The speed at which work is done?
the speed at which work is done is velocity
Your heater blower will just work on high speed?
The blower motor speed resistor is burned out. The high speed function bypasses the resistor. The speed resistor is generally located near to the blower motor.
Have a 5 ton condenser with a 5 ton coil have a 3 ton drive furnace any way this will work or will you have to get a 5 ton drive furnace?
You may be able to turn up the blower speed but you will probably still not get the appropriate cfm. You may be able to swap out the blower but you may run into problems with fitting the new one in place or the proper sizing of the return and supply duct work.

Why the Blower motor not work on high speed on a jimmy 97?
If the blower works on slower speeds only I would suspect the high speed blower motor relay (under the hood in the power distribution box) or the switch itself. The blower speed resistor is working if all the slower speeds work.
What would cause your blower motor to work on only one speed on a 97 Chevy k1500?
If the one speed it works on is high speed, it is the blower motor speed resisitor that is bad.
Your ac want blow how do you fix it?
If you are saying the blower motor will not work, then check the fuse.

What would cause the blower motor on a 2002 Malibu to work only at high speed?
I would suspect the blower motor speed resister is shot.
What else would stop a blower motor from changing speed 1234speed dont work?
If you only have high speed I would blame the blower speed resister. If you have no speeds and the fuse is good, I would blame the blower motor or the switch.
