Honda Accord EXR '91 fan problem

[Super Giraffe]

Hi everybody,

I have a Honda Accord EXR '91, when I start the car the engine warms up normally but the blower motor doesn't turn on so I don't get any heating in the cabin, unless I drive at 100kph (I guess that forces the air through). Anyways, I've replaced the heater/rear defroster fuse in the driver side fusebox and tested the blower motor which is fine. I don't why the fan isn't blowing!

Engine warm, no fan, cabin cold. Any suggestions?

Find a route to work with no stop signs or traffic lights? Haw Haw.

Was the fuse blown? Was the heater working perfectly before, or did it only work on some of the speed settings when it quit altogether? I'm hinting about the resistor pack. . .

An update, because I went through alot to figure out what was wrong.

First I tried to remove the blower motor, that took forever because I didn't know that you need to remove the control unit on the floor underneath the carpet to get enough clearance to slide the blower motor assembly down and out.

Then I went around looking for a new blower motor assembly, the motor itself is $180 CDN and doesn't include the assembly which I need (couldn't remove the blower wheels from the old motor). I went to my dad's friend with the blower motor and asked him if he could fix the motor or find another motor, he hooked it up to a car battery and it worked.

So I put it back in the car and two weeks later it stopped working again. This time I went to a mechanic who said that the blower motor assembly needed to be replaced, I pointed out that it had worked before. He said that was because it was getting full voltage and current direct to the battery, which it doesn't in normal operation.
Estimate was $380 CDN.

So I went to the auto junkyard and got a used blower motor assembly, and installed that. Five or six weeks from then and the fan still works.

The Haynes Honda Accord '91 manual was useless. The Chilton's manual was slightly more helpful (it actually mentioned the EXR). Newsgroups and google were really helpful.

Thanks for the post. I was wondering how the heck to get that motor out. The damn Hanes manual just pretty much shows it out after pulling a few screws so I thought I must be doing something wrong. Gonna go check under the carpet now and then visit the local wrecker. How much did you get the blower motor for? I'm in Canada too.
