the AC removes moisture On my 2008 Corolla, the AC light does not light up when the defroster is turned on. However, it DOES appear that the AC compressor is used. (my 2008 is the same as 2003 thru 2007, it is not the redesigned Corolla which an 09 in the USA.)
ac motor
The power source is AC. Hence AC is used. DC application is limited.
It wont work for AC measurements. Not designed for AC application

You do not use AC to megger a device, because the purpose of meggering is to measure the insulation resistance of the device. You use DC to do that. If you used AC, you would be unable to differentiate between insulation leakage and capacitance.
Yes, the windshield defroster will turn the A/C compressor on.
If the AC or Defroster is on, many vehicles will also turn on the cooling fan.
Many auto manufacturers engage the AC compressor when the defroster is used because the AC system also dries the air. In a humid environment the drying effect of the AC can help keep the windshield clear.
Bearing in blower motor?
My ac blows only in the defroster and not any of the other vents i have 98 ford windstar 3.8 v6
To help dehumidify the air
Turn the defroster on. If you have a separate AC switch, turn it on also. The AC should come on with the defroster automatically, but might not. If no AC, set the vent control to outside air instead of recirculate.
If you have the defroster on, the ac comes on automatically.
If you have the defroster in the on position the ac will do that.
Most of the time it means that the AC refrigerant has leaked out or that the AC doesn't work for some reason. Understand that most vehicles engage the AC when the defroster is on because the AC will dry the air, clearing the windshield quicker. If you turn on the Defroster and the AC light flashes, it just means that the AC won't turn on.
The ac unit compressor will run when it is in defroster mode and heat setting is on.
If the squeeling is under the hood it is probably the AC belt. If the defroster is on the AC is on. Just tighten the belt. If the squeeling is under the hood it is probably the AC belt. If the defroster is on the AC is on. Just tighten the belt.
