Did this video help you?

Hustler LT: buuu ,you dont know what is current what is voltage,all test you did was VOLTAGE testing not current

Always Armed88: I have a 03 taurus ses and it blows heat and cold air. The thing is it will not change from defrost to cabin or floor. It stays blowing out of the defrost vents. Any help would be appreciated! 

MiBzAn: You just saved me, a frozen Canadian, over $100 that I don't have - thank you so much! 

Richard Murray: How do you get the electrical connector off.  I pulled on the rubber part just like you did in the video and the thing won't budge.  I tried using a screwdriver to pry it and all I did was bust off all the hard plastic parts.

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!

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 video.. :)

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.

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? 

Ronnie Figueroa: you are a great person, thank you for this video it helped me a lot. 

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 !

maxie0789: When I test the voltage on the switch it jumps up to 18+. What could that mean?

maxie0789: Hey. I'm getting a high voltage when I test the switch power. What could that mean?

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?

MrScotty46: my blower switch works 'sometimes'

James Laskowski: Hammer tap restarted blower motor on 2000 xlt ford ranger

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?

Ray Keefer: My 97 sl1 saturn the blower works but not on high, what could it be.
