Could be the blower motor resistor or the blower fan switch or fuses check fuses first then move on try using a jumper wire to the fan motor if it works good if not its done do this from the + on the battery
Replace the blower motor resistor assembly. To locate the electrical connector for the blower motor resister, it is usually attached to a heating or air conditioning Duct, or the blower motor case. You can also trace the Purple Wire from the blower motor back to the resister. Also make sure that the blower fan is not jamed up with somthing in side and will spin freely,or binding same thing, this will also cause the fuse to blow right away. And does the motor actually spin a bit before it blows the fuse or does it blow the fuse at the same time the switch is turned on? Good Luck and have a good XMASS.
need more info? Heater blowing cold air? Heater not blowing at all? If neither heat or air are blowing then it's just the blower fan. Easy to replace and fairly cheap.
Per your description, I believe you may have a blower fan relay that is stuck closed. Remove the relay from the under-hood fuse center and see if the fan stops. If it does stop, put the relay in slowly and see if you here the relay "click" and the fan come back on. Let me know. Regards,
I would check the AC or blower fuse to start with. If you have the drivers manual it will show you where the fuse box is. Typically there are at least two boxes to check. One in the Engine compartment and one in the passenger cabin.
Look inside the lid of the fuse box to see which fuse may apply to the AC circuits or the blower and check to see if they are blow. the metal link between the two posts that plug in. If the link is missing you need to replace the fuse with one of the same rating. Make sure you know where you took the fuse out from and put it back in the same slot if its good. Check all the main fuses if possible to see if any have blown and replace if they have.
no, did you replace the passenger cabin filter? chance are it is to late...i just found out today it is best to bc it puts pressure on the blower....its in the glove box..
