92 Integra - Heater Blower stopped NOT resistor!

Interesting but I have a similar problem on my 1991 Acura
The blower doesn't run and I think that it's frozen.
I don't have power on the cigarette socket also.
All the fuses look OK.

One day I started the car and a smell of pc board burning and smoke
came inside of the car.
The fan switch was in the middle position and didn't turn. I believe
that a high current melted the contacts on that position.
I forced the switch and it rotated.
I started to follow the book instructions but I gave up after removing
a few  panels. Acceptability of the blower is not easy.
I have the manual but doesn't help. I believe the manual isn't an
accurate representation of the actual circuit.
I am thinking of selling the car as is and let some one fix it.

The service manual was available on the Internet thanks to Tegger

I must also add that the radio also lost power

Both the cigarette lighter and the radio are fed by a 10-amp fuse in thge
under-dash fuse box. Check for a blown one.

As for the blower itself, Honda calls the entire duct assembly the
"blower", which kind of confuses things. All you want is the /motor/. The
motor should drop out of the bottom of the duct with nothing more than the
removal of the three bolts you can see from the bottom. There should be no
need to remove the duct from the car.

@h5g2000vbf.googlegroups.com:


The blower motor is always hot, with the switch providing ground, and the
resistor between them.

Pull the fan-motor's connector and see if you have voltage there. If NO,
then you have an open between the ignition switch and the blower motor. If
YES, then the motor is seized.

It's very dificult to get at one of the screws . I may have another
try.
Thank you Tegger

John

You're probably meaning the screw closest to the passenger side of the car.
That one is really tough.

What you can do is to remove the bolt you see that faces forwards, at the
bottom of the white plastic blower housing. This should allow you to pull
the housing rearwards just enough to get the screw free. What really helps
is one of those combination wrenches that has a tiny ratchet in the closed
end.

With the cold weather coming in I gave up and toke the car to the
Acura dealer. Nice and pleasant people.

Price for a new Acura blower app. $460

I asked them to give me an estimate and this morning they contacted me
The approximate estimate was for a new blower to replace the frozen
one, a replacement of the ignition switch and labor. About $600 tax
included.
The seized blower, destroyed part of the switch. That was the reason
why other electrical accessories stopped working.

They knew that I wasn't going to pay that price for a the blower but
told me that they have found a new one for about $200.
The car will  be ready tomorrow.
The car should last another Winter.

They told me that it is impossible to fix the old blower. I am going
to investigate.

Thank you for the help

John

Just received the car.
Total cost  $660

Looking at the old blower I concluded that I could have fix it but any
way, I am to old to work under the dash.

Should last one more Winter. Not bad for a 20 years old car
