Car Fan Blower Motor Questions and Answers
This category contains featured questions as examples. They relate to most vehicles.
Question: 1999 Cadillac
Seville SLS mileage: 90,000. The blower to
the heater and A/C has stopped. The controls
seem to work because I can hear the dampers
moving when I hit the auto button. The fuses
are ok, the relay is ok and with a meter
there is 12 volts going to the blower motor.
The housing where the motor has cast into
the plastic "cut here to remove motor". Do
you just cut this open like a can and how do
you repair the cuts? Have I checked
everything there is to check before I start
surgery? Also the plastic housing that the
motor goes into is broken and chipping off
all the way across the firewall. Is this
normal?
Answer: Yes you have to
cut the housing to remove the blower motor.
Your local parts house should have some tar
like sealer that you can use reseal it when
you are done. We are not quite sure what you
mean by the chipping of the plastic housing
but it does not sound normal to us.
Question: 1999
Isuzu Rodeo 3.2L V6 mileage: 95,000.
I am having a problem with my fan/blower. I
can tell that the air is hot when using the
heater and cold when using the AC, but the
fan will not blow. I checked the fuse and
also changed it and it still doesn't work.
Answer: Check for
12-volts at the blower motor. If 12 volts is
present, replace the blower motor. If not,
check for a faulty relay or fan switch.

Question:
1999 Ford Thunderbird LX 4.6 mileage: 51,100.
The fan stopped working on it today. I
looked in the fuse panel to see if there was
a blown fuse, but I could not locate it.
We did not receive the owner’s manual with
the car. I have looked in the
engine compartment for the blower relay.
I could not tell which one was which on the
control panel there either. The heater
or AC is not working since the fan is not
blowing. Any info that you can give me
would be very well appreciated.
Answer:
The blower motor may have failed.
Test it by checking for 12-volts at the
blower motor with the blower switch on. If
so replace the blower motor
Question:
1998 Mercury Cougar. The cooling fan
will not stop running. I already
replaced the temperature sensor but it did
not fix the problem. I have read that
for air-conditioned cars, there is a fan
controller but I do not know where to find
it or what it looks like. Another
problem is the blower fan; it will not blow
any air. I already tested the fan, it
runs in another car so it works, and I do
not know what else can be wrong with it
because the fuses are fine, and all the
connections are well plugged.
Answer: First off, the fan
control is located behind the glove box.
It is approximately 3 inches by 4 inches and
black in color. Secondly, the blower
fan problem is probably a faulty fan switch
or the resister block for the blower motor.
Question:
1999 Pontiac Grand Am quad 4 mileage:
104,000. Hi. I have a 1999 Grand
Am with a High Output Quad 4. The
blower motor for the heater/air conditioning
suddenly stopped working. I checked
the fuse, and it was OK. When I change
the heater settings, I hear the usual
pneumatic sounds that go with it, so I know
that the car is responding to the controls,
there just is not any forced air. If
it's of any consequence, I just had the
alternator replaced 2 weeks ago, due to a
very obviously bad front bearing.
Answer:
First check to see that you have 12 volts to
the blower motor. If yes, blower motor
has probably failed. If no, it may be
the blower motor relay or there is a speed
control resister causing your problem.
Question:
2004 Pontiac GTO miles: 67,990 I am trying
to change the blower motor and cannot locate
it. I have checked along the firewall
and even behind the glove box. Can you
help me?
Answer:
The blower motor is located behind the
heater box duct. Remove the plastic
shielding round area to access blower motor.
Question:
2003 Lincoln Towncar, mileage: 106,000. The
blower motor keeps blowing a fuse after a
few minutes of running. In addition, some
kind of fog comes out of the vents when
driving even though the system is not on.
Can I repair this myself?
Answer:
The blower motor problem may be something as
simple as to small an amp fuse or the blower
motor is shorting out and the motor needing
replacement. The fog coming out of the vents
is probably the result of a small coolant
leak in the heater core.
