The heater fan on my 91 doesn't work. I checked all the fuses and they're all good. The lights on it all come on, but the fan doesn't blow. No a/c, no heater/defroster. Is there a way to check if it's the motor that's burnt out? Or could it be the switch? How do I tell without replacing everything? Please help, foggy windows suck!!

probably the blower motor. Its located under the pass. side glovebox. There is a resistor on the side of the blower motor cage, you can try checking the ohms on that but either way, the entire blower motor cage has to come out to remove/check any of those componentsOriginally posted by duffmanivxx View Post

there is a troubleshooting flowchart in the Helms manual for this. Maybe someone on here can post it for you. I don't have an electronic copy, just a paperback. Sorry!Comment

all good man, ill see what i can find. thanksComment

I talked to a guy at a shop by my house. He said it could be the fan motor or the switch. Does anyone know how to test each one, so I don't replace something that isn't broken??Comment

the fan only has ground and power..... so just touch the power wire to the + battery terminal..... if the fan doesn't turn on then get a new fan at autozone for $50...Comment

Good idea, thanks again.Comment

yeah oem fans flow at like....270-280 cfm.... but because it comes with a shroud it makes it really efficient.
your universal 12" fans at autozone and ect flows much higher... IIRC they are almost always +600cfm...Comment

if it is the fan, i think i'm gonna check the junk yard first. they had a lot of accords, maybe ill get lucky...depending on how much they want for it.

Set the fan speed to max and test the 2 wire plug by the passenger kick panel. There should be 12V. If there is 12V and the blower doesn't work at any speed, the blower motor is dead. If the resistor was dead, it should still work at max speed.
When the motor dies, it's almost always the brushes inside that have worn out. If possible, it is a better bet to buy a new motor as the junkyard ones are just as old (unless you get lucky and find one with a motor that was just replaced). I only say this because these cars can be a pain in the ass (especially the ones with A/C) to swap out as you need to remove the whole blower box from under the dash unlike the older and newer Accords where you can just pop the motor out from underneath.Comment

Right on, I'll get out the meter and check it out. I'll just buy a new fan if that's the problem. Thanks again for all your help fellas!!Comment
