    My apology!



    What I meant is that the "Blower" inside the car is not working!



    Which I need to check first?

    Mine is a honda ridgeline. Mileage around 12,000+ When I turned the dial for the fan blower, there was a sound of hesitation from under the hood, and no air was blowing at all despite the fact the display read "a/c on" I tried turning it off and waiting, but this did not change the fact the fan was not blowing air. Could it be a fuse? And if so, where would i find such fuse? under the hood?

    I found the problem to my 1992 Honda Accord regarding blower fan not runing.

    Found that the fan is still working after giving a hard tab at the bottom of the blower housing (heard hesitation humming noise)from the fan. My conclusion is that the fan motor (shaft) needed cleaning & a lube job if it is not a seal unit. Otherwise the fan need to be replace soon.



    Seabrezes711 might have the same problem as mind. Good luck.

    Your message is a little confusing; what is it that is NOT working?



    Generally, 'blower' refers to the air mover inside the car that pushes air through the heat exchanger to warm and the condenser when cooling.

    The AC 'fan' is the independent cooling fan that draws air through an extra radiator mounted under the hood that dumps heat collected in the car.

Hope you have both fixed your problem by now; my system has been down.

In most auto applications, the bearings of small fans and motors are made of sintered phosphor bronze with graphite or petroleum lubricant embedded in it.
Since there isn't much load on these, the bearings can outlast the rest of the car but they do have a tendency to get gummy and since the fan motor doesn't have much torque, it may have trouble overcoming the stickiness and start turning.

If it wasn't for the buried location of most blowers, it would be a simple job to flush out the bearings with a penetrating lubricant such as WD-40 that is mostly volatile and doesn't leave much residue behind to complicate (gum up) things again.

This problem is common to some computer cooling fans too although many of the small CPU cooling fans actually have PLASTIC bearings!
Including some that were clearly marked as 'ball bearings.'

My blower for my heat inside my 1992 honda accord stop working.I check the fuses they all good .What"s next for troube shooting.


If you park your car around leafy trees, it's possible your blower sucked in leaves and jammed it, which happened to mine. On the other hand, your blower motor could just be worn out. Either way, you'll have to remove it and check for blockage and check for continuity, meaning make sure the motor is still electrically functional. It is also possible that your fan switch went out, or a broken wire behind the switch. I would check the switch before tearing into the ducting to get to the fan.

The heater on my 96 accord lx wont work. i hooked a toggle switch up and the blower and the hot and cold switch work but fan speeds do not. I was told it was a possible resistor problem. where do i look?


It is not a resistor you blower motor is going out it needs to be replaced. When fan speeds don't work as they should this is clearly the problem.

2002 Honda Odyssey fan only works at high speed. The A/C compress


Usually when the blower fan only operates on hi speed, its because of a failed blower motor resistor. You still have hi speed because on hi, the power going to the blower motor goes directly to it, as opposed to the lower speeds, when the power is routed through the resistor, thus lowering the voltage, which in turn lowers the speed of the fan. The resistor is usually located near the blower motor itself, under the hood back near the firewall.

1990 honda accord ac blower motor will not work


Check 7.5 fuse (#8) inside the car by your left foot and check the 30 amp fuse in the engine compartment (according to your diagram on the inside of your fuse box lid).

You can replace the fan motor pretty easy but you'll want to unplug it and test it first by running an automotive battery to the plugs of the fan with 2 jumper wires. The fan is above the right foot of the passenger area. There are three 8mm screws to remove then it drops out. Careful with the wiring.
If your fan is still good, you'll have to consider removing your knob and switch assembly to see if something is unplugged in there. Good luck.
