Why is my car AC blowing slow?
Nine times out of 10, weak airflow is caused by a clogged up cabin air filter. Over time, this filter catches all dirt and debris, which can build up and slow or stop the flow of air. It’s typically located under the dash on the passenger side or inside the glove box and should be cleaned or replaced regularly.
Why does my car air conditioner only work on high?
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.
Why did my car stop blowing air?
Your air intake is clogged, meaning that air isn’t getting in from the outside at all or isn’t circulating properly. There is a blown fuse in the ventilation system. Electrical issues such as a bad relay. Damaged blower motor.
What are symptoms of low freon in a car?
Well, there are a few signs to look for.
- Room Temperature Air. One of the most characteristic symptoms of low freon is the presence of room temperature air blowing from the vents.
- Visible Leaks. Of course, another sign of low freon levels is a visible leak.
- Clutch Doesn’t Engage.
- Ice on Compressor.
How do you know if your car blower motor is bad?
You might also hear ongoing whirring noises, or noises that change or get louder if you increase the fan speed. These are all signs of problems with the blower motor. In some cases, you may even notice smoke or smells of burning while driving, in which case you should pull over immediately.
What happens when a blower fan goes bad?
There’s a switch or something located under the blower fan that goes bad, and not all the fan speeds will keep working. Like on mine, the lowest fan speed no longer works, but the rest do. That’s the blower resistor. When that goes bad the highest speed will still work because the current goes directly to the blower motor, not through the resistor.
Where is the AC fuse on a Toyota Fan?
There should be a 7.5A AC fuse, above it the 30A heater circuit breaker, and above that the heater relay. ok ill give it a check tonight , i also dont believe i have a ac button
