My 91 Accord EX ac/heater blower sometimes quit working.
While driving on the road it will just come back on.
I checked the fuse panel in driver side kick panel and the fuse is good.
Where is the blower relay located?
How do I get to the blower power wire connector to check voltage?
Thanks.

blower motor is uder the dash, I would check the wiring and test with another motor if the wiring and power check out (at the plug)

u need a blower motor ,,, , what happens is that there are some brushes to make motor work and when u hit a bump, it jars them just enough to make contact .and make it work ........remove blower and replace motor,,get a motor from autozone

My car is doing something along the same lines, but my question is this: does anybody know if you can buy a more powerful blower motor? The one in my Accord has always been weak, and if I have to replace it, can I get a better one? I've searched around, but never really found anything. Found aftermarket stuff, but it said it was OEM replacement, and didn't say anything about blowing harder.

it should blow pretty good if in max speed maybe u got the evap partially plugged

Thanks, I will check the connector and motor brushes. Is it easy to pull out the blower motor?
What do I need to remove to get to the motor? Remove the dash? Just the glove box?
The car has 300k miles. Does it sound like the blower motor will break or fail at this mileage?
Thanks.

I think I found my blower problem. The blower wheel was stuck from debris buildup.
Maybe from too much dust and debris from outside air damper being open most of the time.

I pulled the black cover under the glove compartment and it exposed the blower wheel and dampers. I put the a/c in recirculation to have access to the blower wheel. I spun the blower wheel by hand to get it unstuck and it turned freely. Switched the blower speed to max and it started spinning again. I sprayed some silicon lube on the shaft hoping some will get inside the bearings or bushings. Switched the blower again to max and problem solved.

For troubleshooting purposes, there are three connectors. The first five wire connector came from the blower speed selector switch and into the dropping resistor for blower speed control.
The second two-wire connector is the blower motor leads. One is power wire from the resistor pack and the other is a grounding wire to the blower relay.
The third connector is the control and power wires for the fresh air/recirc blower dampers.
Hope this helps anybody with same problem.

If you have a clogged evaporator coil, that will restrict the airflow.
The blower housing can be pulled out from under the glove compartment.
It is secured by three 10mm hex nuts. You can only access the three 10mm nuts if you remove the glove compartment which is secured by four phillips screws in the sides of the hinges. The screws are concealed by a leather material and needs to be pushed to the side to reveal the screws.
You also have to undo the clamp phillips screw on the top of the blower housing.
Once you pull the blower housing, the inlet side of the evaporator coil will be exposed.
Get a tooth brush and brush off the dust build up. Then follow up with a coil cleaner for final cleaning.

You need a blower motor , it will quit on u again .

AccordEX1991

We'll see. Important thing is I already know how to pull it out.
If it quits, let it be. Just trying to stretch the life out of the motor.
If it still spins, just let it spin until it stops. For how long, you'll never know.
Thanks for the replies.
