Car AC Not Blowing Air From Vents

Car AC Not Blowing Air From Vents


If air doesn't blow out at all in ac vents at any fan setting, it is a problem of a bower that is not working. Probably the blown fuse or failed blower motor.

The possible reason why car AC not blowing air from vents

(1) Car blower not working on all settings because of a blown fuse.
(2) Car blower not working on all settings because of a failed motor blower.


First off, we need to clear something up. The "blower" and the "fan" are the same things. We used the word "fan" in the problem description because it's a more familiar term. The official name for it (as used by mechanics) is "blower".

Now then, it should be obvious that if the air isn't blowing from the vents at any fan/blower setting, the blower must not be working. Two common causes of this are...

Blown Fuse - Like most electrical devices, the blower has a fuse as part of its circuit. This fuse can "pop" for one reason or another. This will immediately cause the blower to stop working.

Failed Blower Motor - The blower motor is the heart of the blower and, as one might guess, it drives the blower wheel which in turn, blows air. Of course then, if the blower motor has failed, the blower won't work. Another possible, but rare, cause of an inoperative blower is a faulty dashboard fan/blower switch.

What to do?

First off, locate this vehicle's fuse box. Refer to the owner's manual if you aren't sure where it's located. Once you've found the box, find the particular fuse that is associated with the blower (it should be labeled either "Heater" or "A/C"). Examine this fuse to see if it has blown. If so, replace it with a fuse that has an identical amperage rating (refer to owner's manual for this information).

If the blower works but then fails again, there is likely a short circuit somewhere. You'll need professional assistance in this case. If the fuse was intact, you likely have a failed blower motor or a problem with the switch's wiring. Take this vehicle to a qualified mechanic for inspection and repair. Try to find a mechanic that specializes in A/C and heater repair.

Car Not Blowing Air

When the car ac is not blowing air from vents in the car it is a sign of a faulty blower fan or air duct blockage. A faulty blower fan can make the car ac stopped working suddenly.
