The thermostat may be sticking shut which would cause you to loose heat inside or you may just be low and antifreeze. Check your antifreeze level if it is full then get a new themostat and if that don't work your heater core may be going bad.
If the heater core in your vehicle goes out, you will not be able to use your heater or defroster. You will also notice the smell of antifreeze throughout the vehicle and possibly a film on the windshield from the antifreeze.
The delay in shifting from heater to defroster in your car is primarily due to the time it takes for the engine coolant to warm up. The heater uses hot coolant from the engine to warm the air, and until the engine reaches a sufficient temperature, the air blown into the cabin will not be warm enough for defrosting. Additionally, the defroster setting often requires the air to be redirected through a different duct, which may also contribute to the delay.
The answer is no because the civic was redesigned in 2001 and also the trans also changes too.
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.
Most common things are Thermostat or a bad heater core but could also be something blocking the door down by the heater core. I changed my Thermostat and Heater control Valve to find out a pencil fell in the defroster and prevented the door from closing. Hope this helps.
The most likely reason would be because you also have the defroster turned on with your heater. The defroster causes the A/C compressor to kick on which helps remove extra moisture in the air keeping your windows from fogging. The A/C compressor is linked to a "kick up" that brings the RPMs up to keep your engine from stalling due to the extra load possibly causing a surge.
In the 2002 Hyundai Santa Fe, the heater and defroster fan is located within the dashboard, specifically behind the glove compartment. To access it, you'll typically need to remove the glove box and possibly some surrounding panels. The fan is part of the HVAC (heating, ventilation, and air conditioning) system, which also includes the blower motor.
If it is coolant from the heater core, you should be able to smell a sweet odor when you run the heater. You can taste it also, it should be sweet. It could be the AC drain plugged also. The AC runs with the defroster to keep the windows clear so there is condensation even in the winter.
To repair the rear window heater on a Fiat Brava, first check the fuse related to the rear defroster; replace it if necessary. Next, inspect the heating element for any visible damage or breaks in the conductive lines on the glass. If damaged, you can use a rear window defroster repair kit to re-establish the connections. Lastly, ensure the switch and wiring are functioning properly, as any faults there could also affect the heater's operation.
the recommended is 5w-30. you can also use 10w-30.
it is normal. when you use the defroster, the air conditioner is also working to help dry the air passing over the windshield. this moisture is condensed by the cool evaporator and drained through the floor of the car.
A person could buy a replacement seat for a Honda Civic 2001 from the website Auto Parts Warehouse, JC Whitney, and the Honda Parts Store. One can also buy from the official Honda estore.
