Pour warm/hot water on the windows. It works every time! If the defroster and heating units are working correctly I don't understand why the inside windshield would still be fogged up. I have a 2000 Plymouth Breeze and the owners manual says when using the defroster be sure the the vent control knob is turned to outside air position. Hopefully this will work. NEVER!!! EVER!!! EVEEEEERRRRR!!!!!! pour hot water on your cold windshield! The temperature change WILL pop your windshield.
It only stays on when the air flow is turned to defrost. It does this because the air condition has a dryer on it that dries the air which defrosts the windshield better.
electric defrost, using an electric heater that the air from the evap fans blows over and defrosts the coil, usually time initiated temperature terminated
The fastest way to defrost a windshield is to turn the defrost vent on without heat or simply open the windows. Another option is to warm the inside of the car by turning the heater on.
no heat to front window went defrost is on
on the dash below the windshield.
does fan door motorized or on a vaccuum line when you switch from AC to defrost?
Defrost setting pulls all outside air.
Yes, the ac will run in the defrost position to dry the windshield.
Start driving with your air conditioning on defrost, the AC will defog the windshield but you need to be moving.
The defrost function simply directs air over the inside of you windshield. It's temperature is controlled by the temperature dial on your environmental controls.
Yes, the windshield defroster will turn the A/C compressor on.
If it only does this after a rain, chances are you have a leaking windshield. Or the aircond. drain is clogged, even if you are only using the defrost with heat the air-cond. runs with the defrost.
