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.
