Why does my AC blow harder when I accelerate?
Why does my AC blow harder when I accelerate?
Change in engine vacuum causes something to change the way the blowing air sounds, such as a blend door closing/opening under the dash. #2. The voltage to the blower motor increases, resulting in it actually blowing harder.
Why does my air conditioner slow down when I Turn on the fan?
That’s when you get a change in airflow. When the door doesn’t operate properly, it may sound like a Blower motor slows down when accelerating Sometimes, when a vacuum motor defaults due to loss of vacuum, and the system uses two vacuum motors to switch modes, it may seem as if the fan is losing speed.
Why does the blower motor slow down when accelerating?
However, if the vacuum motor develops a small leak, or there is a leak in the vacuum hose or the dashboard switch, the drop in vacuum may be too much to overcome. That’s when you get a change in airflow. When the door doesn’t operate properly, it may sound like a Blower motor slows down when accelerating
Why does my vacuum fan slow down when I open the door?
Sometimes, when a vacuum motor defaults due to loss of vacuum, and the system uses two vacuum motors to switch modes, it may seem as if the fan is losing speed. What is really happening is that one door is closing off the airflow and the fan only sounds as if it’s slowing down.
Why does a / C stop blowing through vents as I accelerate?
I was sitting stopped, turned on the A/C and it started blowing nice and cold as normal. After i started accelerating, the flow through the vents slowed and finally stopped. As it stopped, i heard the compressor kick into overdrive (like it does when it is cooling the air before blowing it through the vents right as you turn it on.)

Why does my Van Fan stop blowing when I accelerate?
When I drive my 6.0 diesel van ,my cooling fan works normally. When I put on the AC, in a few seconds the clutch fan , starts sounding like a school bus.after a few min. on the highway it stops for a … read more What would cause car a/c to not cool when car is accelerating?
