Bad fan motor, blower motor resistor or failed switch. Test for current to the fan.

Minr did the same. It was the switch on the dash. Advance auto or auto zone can get it. Normally under $50

SOURCE: fan blower stopped working

I had the same problem and Ia m working to resolve it.
You need to remove the blover under the glove box it's very easy to remove. 1) remove the glove box, 2) the metalic suport that it's hold by 4 screws and finally remove the 3 screws that holds the blower. Take it off and remove the coverplate of the motor ( 2 screws) and
check the brushes. In my case they were worn out. So you need to buy a new motor with the blower aprox $50 or try to replace the brushes.

Your problem is on the fan speed switch on the dash board. You can get it from the dealer for $50.00 or you can get the whole control assembly with all the switches from a junk yard for about $50.00. I had the same problem and that's what I did.
Good luck.

On idle the engine warms but no heat out of heater. Had system purged and no air. This is a 2010 Nissan xterra


The heater control valve could be stuck in the closed position. You say that you have no air. Are you saying there is no air coming out of the vents or no Air Conditioning? If you have no air coming out of the vents and you don't hear the fan, could be a fuse to the fan is shot or maybe your switch is not working. If the fan is not working and your driving and your car is up to operating temp. you should feel some heat coming out of the vents or defrosters. The chances of your heater core being plugged up could happen if someone used some kind of stop leak in the radiator and didn't follow the directions. Well that should have you confused enough.

The fans and air con do not work ... It's not a blown fuse .. Any ideas what it could be thanks


Possibly a broken AC switch. Possibly it is low on refrigerant. It is a good idea to determine if the air compressor is working, as well. The compressor clutch will not kick in if the gas pressure is too low.

My heater stopped working. is there a relay switch that might of went bad? fuse good, fan good also.


Kinda sounds like you have a clogged heater core, if the fan is working but it is blowing cold air that is normally either the coolant is to low or the heater core is clogged.

Heater fan in 1991 Pontiac sunbird stopped working. We have replaced fuses, and the fan motor. Still not working, continues to blow the fuses. What to do?


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.

My air conditioning and heater work but my air conditioning/ heater fan does not turn on


You need to get to your fan and test the resistance on the fan harness. If that checks out OK I would look at the switch. I am surfe you have already checked the fuse.

Air conditioning blower stays on at all times.


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.

Air condition


Check the following fuses:
10 amp GAUGE under the dash, and the 40 amp HEATER under the hood.
If both fuses are good, I suspect that you may either have a bad fan switch or a bad heater fan motor. The switches are rare to fail, I would suspect the heater motor first. Please try this: Turn the key on; turn the fan switch to high. Look under & behind the glovebox, for the bottom of the heater fan motor. Round thing with 3 screws holding it to the heater box. Using a small hammer, or something that you can tap with, tap on the bottom of the heater fan motor. You just may jar the motor enough to make it run. If it comes back on, you may need to replace it at some point in the near future. Worked for me quite a few times. Try that, repost to me what happens. Hope this helps.
