My car was standing for a couple of months while doing a repair and now for
some reason, the heater fan has stopped blowing.

I have checked the fuse but this hasnt blown so i'm at a loss as to why
this has stopped working all of a sudden. I know the switch dial is
working as you can hear the air condition ing unit kick in when switched
on but the fan isnt rotating to blow in the cooled air!

Can anyone help?

That's confusing... isnt there a separate switch for fan speed?

Anyway, start at the blower motor and work back. If there's a multiwire
connection in that harness attached to the heater assembly, then pull it
out and check it.

Otherwise, did you disturb wiring in any way while doing the repair?

The switch has a turning mechanism for the fan and you push the switch in
to activate the air conditionoing. YOu obviously wouldnt want the air con
on with no fan movement.

I'm not quite sure what it is your asking me to do there? I'm not a pro at
the mechanic thing but i'm alright on electronics so you might need to talk
in a bit more plain english for me to understand.

Thanks for your help so far!

If you're 'okay' at electronics, then what I wrote shouldnt be too hard to
grasp.

The blower runs on DC, probably two wires going to it. They are in a
harness, follow the harness....

Just WHAT dont you understand?!!

There's a pretty good chance that the resistor pack which controls the fan
speeds needs to be replaced. It's located in the blower motor housing below
the glove box, just above where the front passenger's feet would rest.

It has a 3-wire connector, and is held in place with a couple of machine
screws. Besides the 3 resistors of various sizes, there's also a thermal
fuse that opens when the temp exceeds about 215 degrees, or the current
exceeds 15 amps. It's also possible that the 3-wire connector is corroded,
and can be cleaned up with a thin file or emery paper. The connector has
a release tab that must be depressed to disconnect it.

If the pack needs to be replaced, it costs about $12 at a Ford dealer.

Aeropars,

First, check to see if the blower motor still works. Unplug the connection
at the blower motor. Run a wire from the positive terminal of the battery
to the blower motor. If the motor willnot work, most likely it needs
replacing. I replaced a blower motor on my 93 Aerostar a month ago after I
checked the old motor in this manner.

Don't know how hard it is to replace a blower motor on an Escort, but the
job was a piece of cake on the Aerostar.

Good luck.
