Hi,
I have Honda Accord, 4 door 4 cyl. A few days back, when I turned heater knob to hot, it did turn but only upto half way between hot and cold. What is more interesting is that although air was blowing in, it was not hot at all. As knob was in middle of hot and cold, I would expect air to be warm after some time. But it was always cold.
I checked knob, its fine.
I don't know what fault can cause knob turning only half and same fault cause no heating of air.
My car has right amount of coolant and its temperature is correct also.
My doubts are on:
1. Control valve. Is it always open? Where is it located? When does it shuts off? If it is shut, should that also not mean that there is no flow of coolant thought radiator and car will get hot after some time. And my engine's temperature is at correct level.
2. Air guiding vents mechanism. My understanding is that the air is guided with vent mechanism to let it pass through either A/C or heater. And this knob is stuck due to vents are stuck which is on the A/c side thats why no heating. My bad luck that at the start of winter, vents are stuck in A/C. Where are the vents located in Accord, 96? Is there any help available on vents mechanism and its repair? I know something related to vacuum is responsible for vents operation, but not much info on this aspect is available to me.
What really is the function of this knob? Is it for turning the vents according to the knob position between hot and cold? Is there anything else it does like controlling flow through control valve or anything else?
If anybody know anything about this type of problem with knob or vents mechanism, please share your experience or your opinion on above.
Also can anybody suggest what type of heater I can use inside car to defog windshields as a short term solution.
