Wires to blower may be crossed or blower resister is bad.

Weak blower motor

Check good voltage and ground for blower motor. Actuators under the dash may be restricting air flow? High speed doesn't usually use a resister.
Check for hvac trouble codes, in my part of the country, some of the national brand autostores will check codes for free, if there are any.
If you think problem with blower motor, itself, replace it. Sometimes, you can remove blower motor, use jumper wires for voltage and ground, using inline fuse, come off the battery, see if it blows like you think it should?

Heater is blowing cold air and there is a noise coming from around the blower motor area?

Check your coolant reserve tank and fill it if needed.

If the coolant is fine try flushing the heater core, follow ChrisFix's instructions in the vid linked below.

How to Flush Heater Core Safely with garden hose

As a side question:
Were there any loose wires that could have been caught near the fan when you replaced it? They'll make a buzz noise if they're touching the fan blades.

I have no heat or air blowing out of my vents. Any ideas?

still nothing,????
why do this backwards. ??
or not using simple diagnosis>?
so really you failed to state the beginning symptoms?
was it just just noise. or noise and no blow.
or the noise is gone,, but my fix broke the blower.
there will no heat not moving, if the blower is dead.
get heat , moving in non circ, mode.?
sure i bet you do an that is SOMETHING.
does the blower make sounds like a normal blower, then if no air flow
the dampers are bad.

blower silent? on all speeds, , do say so.
blower works only on high (sounds) ?
if the blower is running, surely you can hear it spin fast.
and there is no flow, the damper is bad or the blower fan blade set screw
is missing and or loose. did you check that screw first. before.
replacing the motor? id not ever skip that step.
we can not help you ,with no facts or symptoms but still nothing.

AC Heater

It sound like the blower wheel of the blower motor is rubbing the inside of the housing (the smoke). Sounds like the blower wheel rubbing may have burned the inner plastic housing or has come off of the motor shaft inside. Take the blower motor and wheel back out and inspect everything closely I think you will find the problem.

Sentra AC

There's a 10amp fuse that powers the ac clutch relay and compressor. There are 15amp fuses that power the blower motor and the ac control switch. All of those fuses get power from the key switch. The resistor and fan switch provide the ground circuit for the blower motor.
I would want to know if those fuses are getting power, and if the control panel is working. You should be able to ground the blower motor and make it run on high, and that should not have any effect on if the ac compressor is running or not.
It could be a key switch problem in that the circuit is not strong enough to handle the load from the blower and the compressor at the same time.

Heat wont work in my saturn

Your cars blower motor is probably shot from moisture and you should check the resistor also as it runs all the speed functions of the blower motor regards Chris

When i get in my jimmy to go to work its blowing hot air( with the heater on of course) and then there is a creaking noise coming from the blower motor area, then the heater will start blowing cold air...

Because the Main Gear in the Blend Motor has cracked or teeth have chipped and is now not keeping the heat/cold door to the Hot position. 3 fixes: Buy a new Blend motor, takes about 5mins to replace. Buy a new Blend Motor Gear, will take about 30mins to fix. Repair current gear with Epoxy, takes about 30mins and 12hrs for the glue to set up strong enough to use it.

OK. So the blower notor isn't operating. Do you have power to the blower motor? The resistor is new from what I got. If you don't have power to the blower motor, then check the speed control switch and fuses. If you have power at the blower motor, replace the blower motor

My heater fan was making noise but was still blowing the hot air out. Now it makes no noise but blows no air out. I assume the fan/blower motor is bad. How do I replace it?

your blower mototr stopped turning , the noise you heard was one of the cage weights came loose and put the blower cage off ballance, first you need to locate the blower fan and check to make sure it has 12 volts, if so then you need to use a jumper wire to ground the other wire going into the blower motor, if this turns the blower motor on then you have a blower motor resister out and need to replace it.

Ihave a 1992 caddy deville Ican hear the blower motor blowing .

I may have had a similar problem, for a long time my blower motor made a loud howling/roaring noise, hard to explain, but I only heard the noise when the blower was turned on. It continued to blow air for a couple years then just quit, the noise it made continued for another 6 months to a year without air-flow. Finally it quit blowing air at all. I eventually replaced the blower motor and no more noise and air flow was restored. Hopefully you already have fixed this because removing and replacing the blower motor wasn't fun.
