I have a 20001 Honda Oydessey and live in Houston. With Global Warming going on there are occasions where both heater and air conditioning is needed.
Here is the problem. The blower only blows on two setting; High, and when the A/C is set to AUTO and the blower switch is set to Auto. The blower doesn’t work when the switch is moved to other settings. And the air conditioning air is warm when set to the coldest setting.
What can be done to fix this, and is there any connection between the lack of cold A/C air coming out of the vents and the blower not working properly?
There is a resistor pack that controls all but high speed. When one resistor goes out the others seen follow until you get only high and off. The resistors are usually located on the heater box when the cold air comes in.
