Why does my AC only work on Max?
When a blower resistor fails, the highest fan speed usually is the only one that still works because it essentially bypasses the resistor and receives the maximum amount of voltage. When the resistor is working, it reduces the amount of voltage going to the lower fan speeds, so the fan runs slower.
What could it be when you turn your AC on and its has a bad smell?
A foul or rotten air conditioner smell is usually the result of dead rodents or critters stuck in the AC. If you have a ductless/central air conditioning system, lizards and other critters can sometimes go into your indoor unit and make for an unpleasant experience.
Does a bad AC compressor smell?
Electrical odors could indicate a mechanical problem with your AC fan or compressor, wiring issues, or electrical component failure. The first few times the unit kicks on, it may emit a burning odor that can smell electrical and dusty, give it 20 to 30 minutes and see if the smell dissipates.
Why does Max A / C work for You?
Why does MAX A/C work for you? In modern cars, the MAX A/C settings gets an initial burst of outside air in the first few seconds of operation and then starts to recirculate it. It is a hybrid setting that allows you to get cold air as soon as possible.
When to use Max AC or AC in your car?
With that being said, if it is HOT in your car from sitting in a parking lot all day (10+ hours) — would it get your vehicle cooler if you turn on AC and allow your vehicle to “cool” the outside air being pulled in. OR use MAX AC where the HOT cabin air is just cycled throughout your cabin? Ok, let’s break this down a bit.
Why does my air conditioner smell weird when I turn it on?
Mold and Bacteria Probably one of the reasons why there is a distinct smell in your air conditioner when you turn it on is the growth of mold in your air vents. Smells of mildew in your car may be caused by the growth of bacteria. As the car becomes older, bacteria, mold, fungi, and micro-organisms can start to grow.
How to get rid of musty air without a / C?
I also sprayed it directly into the fanbox by removing the glovebox and setting the fan to recurcilate, (which makes the small door on the fanbox open up to take in air from inside the car). This did help get rid of the “mustiness”, but the air still feels somewhat wetter than it should be when you are running it without A/C.
