Both a dehumidifier and an air conditioner remove moisture from the air. Both a fan and an air conditioner move air. An air conditioner, however, cools air which a combination dehumidifier and fan can not do. If it is hot, and especially if there is an elderly person liable to suffer from heat stroke or heat exhaustion, an attempt to replace air conditioning with a dehumidifier and a fan could lead to death.
A Carrier brand dehumidifier propeller fan costs $114.88. The fan blade set kit itself costs only $14.99 (from Emerson).
Replace fan resistor located in airconditioner evaporator box in behind glove box
A dehumidifier is pretty much the same device as an air conditioner. It has a compressor which uses freon to create a cold surface for water to condense on. The fan only is a simple fan that moves air. The fan is the smallest electrical draw as opposed to the dehumidifier. The fan can have a current draw of as little as 1/10 of an amp when the dehumidifier can have a current draw as much as 15 amps when the compressor is running.

Replace the heater/airconditioner fan relay. See other Q & A regarding heater fan running when ignition/engine off. A real pain--drains battery quickly.
It is on the Drivers side fender. There are three relays on the outer fender very close together. One relay for airconditioner compressor clutch one for the fan. If the Fan does not work try turn the airconditioner on and it starts a minute later its not the fan relay. A temperature switch has most likely failed located by the thrermostat. Unplug the switch by the thermostat and the fan should automatically run when engine is started
The HEPA filters cost considerably more.Around fifteen dollars is typical
What is the problem? Do you want to replace fan or fan clutch?
Loose connection?Bad fan motor (windings opening when they get hot)Loose fuse/relay?Bad or worn switch?Bad resistor?
It could be a couple of things but by tour description of a screeching sound, it sounds like it could be the fan out of alighnment, which is pretty common
the relay is under the hood on the drivers side wheel well the fan fuse is under the dash on the drivers side
The dehumidifier removes excess humidity from the air.
