jdunny33: I have a 2002 Impala and the blower just went out when I shifted from park
to reverse. I checked began to check the DCV at the blower motor
itself like you have here but when I was at the blower motor to check for
voltage I do not get a constant voltage. It seems to have a slow drop as I
continue to check it but is by no means constant or anywhere near 12 V.
Would I continue to check the relays/fuses or would this possibly be
something different. Thank you very much in advance.
Kyle Posey: 2001 sl2, blower works great... for the first 15 mins. The blower starts to
slow down. Example: drove 15mins, on highest setting, stopped for red light
and noticed my fan was blowing really slow. Turn it off, wait a few mins,
turn back on and back to normal... everything checks out as far as testing
goes. Any ideas? Thanks!
Aaron Taylor: Thanks for the video Rich. I'll defiantly save this video for studies but I
have a question. My girlfriend have a 2005 Dodge Neon. She puts her heater
on and it squeals very loud immediately. But goes off right away when she
turns the heater off. That would be a Blower Motor issue as well right? Bad
bearing on it perhaps?
Keith Franch: I agree, he is measuring VOLTS not current... The battery voltage to be
completely correct.. Not trying to be a jerk either... Only pointing this
out as it could confuse an inexperienced guy and gal... Thanks for the
A Dill: Why are you going backwards you had power as far as the motor?
megaleadjp: Thanks I just replaced my motor after checking fuses and found power to my
motor. Resistor was good but got no air on all 4 settings.
John Strauss: you are measuring Voltage not Current. Current is measured by putting your
multi meter on Amps not DC and connecting the meter in series within the
circuit you are measuring, which in car circuits is close to impossible.
just a friendly correction. not trying to be a jerk.
douglas tucker: great video ... had my dash all torn apart to replace resistor .. took my
trusty ole simpson 260 V.O.M. out to double check ... found bad wire @ the
motor plug in ... looks like the plug might have been HOT as it is slightly
melted & disfigured. Found the same wire harness @ junkyard for $2.00 and
spliced it in about 4" back from old plug .. works like a charm ... Plenty
of A/C & heat NOW !! Thanks !
James Blackburn-Lynch: My 2001 SL2 blower motor works on low speed (1) and high speed (4) but not
on 2 or 3. I checked the resistor slot as you said in the video and found
12 volts there no matter what setting. I kinda thought the voltage would
change as it went through different resistance circuits. If the resistor
pack is fine, why are 2 and 3 not working? Weirdly, sometimes when the
blower motor is going at speed 1 (which it does as I move it from 1 to 2
and 2 to 3), sometimes it jumps to 4. Any further advice?
Ronnie Figueroa: you are a great person, thank you for this video it helped me a lot.
MrScotty46: my blower switch works 'sometimes'
justmepat Jachimiec: HELP HELP NEED VIDEO REPAIR AC HEATER BLOWER SWITCH, I have told my
mechanic the blower control lever for low is now on high. I no longer have
different control levels. Can I buy the whole bottom AC heater control,
help where can I buy a new one. I live west suburbs Chicago, or maybe I
should go junk yard
maxie0789: When I test the voltage on the switch it jumps up to 18+. What could that
Rob Brown: Hey Rich, when you are checking the ground of the blower motor electrical
connection, what ground in the cabin area are you touching the black
multimeter wire to?
James Laskowski: Hammer tap restarted blower motor on 2000 xlt ford ranger
Ray Keefer: My 97 sl1 saturn the blower works but not on high, what could it be.
Joseph Knight: I'm trying to fix the blower on a 01 Saturn SL1. The blower works when
hooked up to a 12v source. I have good ground and voltage at the blower
connector, but only when there is no load. As soon as I plug the blower in
or add test light I get no voltage at the purple wire. Any ideas? I tried
swapping the relay with the fuel pump relay with no success. When metering
the relay socket, I have good ground and voltage on all three bottom pins
(when the blower switch is on).
maxie0789: Hey. I'm getting a high voltage when I test the switch power. What could
labattsipa: heres a question. my blower is very weak at the third setting,,all the
others are normal. resistor has been changed. whats next?
Altobellodobermans: My meter has two settings on my meter which are DCV and DCA which one do I
use? Also on the ground wire test I have nothing coming up on meter. So
does that mean it is my blower motor thats toast?
Michael Tesfaye: Can this same concept be used to diagnose other makes/models, or is it
specific to the Saturn S-series?
