One reason why an AC heater fan will not work on a Mazda 3 is that the fan is burned out. It will have to be replaced. However, first check to make sure that you have not simply blown a fuse.
Need to know which fuse u want to find out... There are quite a few different fuses in the fuse box. 10A 20A 30A, fuse for fan, fuse for Engine, fuse for horn?
The heater fan may need a new fuse. A licensed mechanic will be able to tell you the exact problem.
Check fan fuse, thermal relay, fan motor. Replace as necessary.
probably needs a fuse either underhood fuse or under dash fuse if not either you will have to bypass directly to the battery
Bad fan motor shorted wire to fan motor shorted switch Disconnect fan motor replace fuse turn on fan and see if fuse blows indicating bad wire to motor if fuse doesn't blow--connect motor if fuse blows bad motor
The fuse panel in my 2006 Mazda 3 is under the hood next to the battery on the driver side. The fuse box is under the passenger side glove box on some models.
There are 2 fuses to be checked for radiator fan. Small one right side under steering wheel in the fuse box. In the cap of fuse box it is written where the one for cooling fan is. If that ok go for the fuse box under hood. it is on passenger side and is of 30A.
In the fuse box under the hood, driver's side
in your anus
All Mazda 3 haves Fuse Box in left side of underhood spase and second box is hidden inside the car, below the foots of passenger.
