Car Forum / Honda Cars / January 2006Blower motor replacement--1991 Accord EX
Hello. It appears that the heater blower motor is kaput in my 1991 Accord EX. I verified that the fuses are OK and that there is voltage at the connector (2P, as I recall.) Questions: 1. The best quote I have so far is $170 for the part. Is there any chance I might be able to rebuild the motor? 2. If I remove the blower assembly and it takes me a few days to get the job done, will the car be driveable? I think the issue here would be whether the control unit behind the glovebox can be reinstalled while the blower assembly is out? 3. Any caveats about doing this job? Thanks -Mark > Hello. > [quoted text clipped - 14 lines] > > 3. Any caveats about doing this job? Got a manual? My 91 Civic's has the steps and drawing for removing/installing the blower motor. www.autozone.com has a manual for your car, free online. Steps should be under "chassis-electrical" or similar. There are troubleshooting steps, as well. > Got a manual? Yes, I have gone through the troubleshooting tips in the factory manual. I have now reached the box labeled "inspect blower motor." Unless there is a way to do this without removing the motor, it is time to crawl under the dashboard with a flashlight and a screwdriver. But manuals don't always tell the whole story. I appreciate practical advice from someone who has done the job. >> Got a manual? > [quoted text clipped - 6 lines] > But manuals don't always tell the whole story.

Haven't tried that. I did verify that battery voltage is present at the 2-P connector per the troubleshooting flowchart. Unless the connector is defective or there is a break in the wiring between the connector and the motor, this _should_ indicate a defective motor. Also, the motor had become a bit noisy over the last few weeks, which suggests to me that it was on its way out. The job doesn't look too intimidating as described in the manual, but I know that manuals don't always tell the entire story. . . >> It's a lot easier than you think.

Could be just worn brushes, however, I don't know if they are replaceable on that motor. Hi Mark The first thing about this problem is that 1. Check the voltage at the 2 pin coupler with varying the blower speed. the specs are in the shop manual. 2. Check the resistance the motor side. 3. Removing the motor is not easy in accord if it is not correctly it may lead to entire HVAC servicing 4. Before doing any work disconnect the battery and remove the ECU. After you have removed the motor..( in case you deciode to do so) re connect the ECU .with this procedure the MIL will not come on. After that you can drive the vehicle. Regards Gaurav Finished! And only one extra screw left over. The hardest part was fitting the blower assembly back into position. -Mark Looks like you already fixed it, but for future readers of this thread... I did succesfully rebuild a blower motor in a 91 Civic Hatchback. All it needed was brushes that I got from ACE hardware.

All > it needed was brushes that I got from ACE hardware. Yeah, once I got everything apart I discovered that the motor was rebuildable. Unfortunately, it is raining like an SOB here every day and I have to work outside, and this is my only vehicle, and so on. So I really wanted to have a new, working motor in hand before I started tearing into the car. My old motor had become a bit noisy in the weeks before the failure, so I speculated that it needed rebushing. That would have complicated a rebuild. In the end I'm not sure what was wrong with it as it does spin when I connect it to the battery. A motor may behave better when not under a load, of course. In any event, everything is back together and working nicely for about $185 (new motor plus a set of deep-reach metric sockets to do the job.) I'm sure that's better than what the Honda dealership would have quoted me. :-) -Mark I too bought the $200 motor before I tore into it, then a couple of weeks later rebuilt the old one just to see if I could. Todd K. >I too bought the $200 motor before I tore into it, then a couple of > weeks later rebuilt the old one just to see if I could. Mine was $150. . .the Carquest version, and definitely not rebuildable. I'll keep my old one available for rebuilding, in case I have to do this job again in two or three years. -Mark > In any event, everything is back together and working nicely > for about $185 (new motor plus a set of deep-reach metric > sockets to do the job.)
