AnswerReplace the blower resistor.
Needs freon? Blown fuse? Broken belt? Possible mechanical problem?
it could be your thermo stat
vacuum line from intake manifold to control unit in dash broken or disconnected
Because something is wrong with it. When it is off it does`nt blow anything, that `s why you only notice it when it is on.
TRY THE AIRCONDITIONING BELT
It could be a low charge, but start by cleaning your filter and see if that helps. If the compressor isn't coming on, it could be burned up.
check you thermostat for the temp setting
the motor is going out it has freon in it but the motor is shot
You are likely in an antarctic region.
ruud furnace only blows cold air, no heat
Its broken Are you a 5 year old or an unfunny comedian?
An automobile's heater that blows only cold air could either be a faulty thermostat or, more likely, a faulty heater core. A trip to a mechanic or shop that specializes in radiator and cooling system repair should be able to diagnose and repair any problems.
It could be low coolant or it could be that the water pump impellers are rusted or worn through.
Condensor is overloading. Had the same problem last year.
Does your compressor clutch run?(you should hear it click in when Ac is turned on) If so you may have a vaccum line unpluged or broken located under the dash arround the hump at the fire wall. Or, possably a bad exchanger valve, Or, your Ac controler may be deffective.

you broke something when you took the blower off .......
VENT TO HEATER CORE IS NOT CLOSING................
number of things. you could have a bad condenser fan motor. bad contactor or a bad run cap for the condenser fan motor.
Could be nothing more than a bad fuse Could be a bad blower motor Could be a bad switch
Air Conditioning works but no air.The fan isn't working. The fan has to come on to move the air. I had same issue few years back....was a $12.00 relay on the side of my hydro heat system
The most common issue is the heater / climate control valve. This can usually be tested in dual mode and checking for change in air circulation.
If the air conditioning pump in the 1993 Chevy Z24 blows perfectly, but won't get cold, it is possible that the Freon needs to be recharged in the air conditioning unit. This can usually be done for about $40 by the consumer.
The heater fan ONLY blows the air, it does not make the temperature of that air. Your heater temperature controls how hot the air is. Adjust your heater temperature for hotter or cooler air.
