8233Eire: You've set your DMM to measure voltage, not current. Current measurement needs to be set on the AMPs scale!
8233Eire: Get your terminology correct; you don't see 'current' your see voltage!
WTC7WasPulled: Hey Richpin I have a 1979 Buick LeSabre Limited with automatic climate control. I have no blower power at all. It came on a couple times lately but soon went out now I can't get it to go on. But when I jump it to the battery it spins fine. I checked the relay and works, I checked resistor pack and all looks fine. What can I do?
mike ryan: yeah but now you are spreading the prongs where relay and plugs goes by using a cotter pin. You are creating and future poor contact . You should use proper test equipment, that cotter pin is a lot thicker than a blade contact on the relay
The Saturn Life: somehow i dont have the blower motor relay cube. im guessing a passenger kicked it off at some point (the cover is missing anyway) how much do the relays go for?
Daniel Heinze: My blower stopped working in all but the highest setting for about a day, now doesn't work at all (2008 chevy malibu LT 2.4l) i'm looking to replace the blower motor resistor but thought I would check the blower motor while I was down there. Does that fact that i'm reading around 15v as opposed to 12v from my purple wire matter? could I have burned up the blower motor?
Ronald Darbyshire: My ac went out when I changed the alt now blower is dying, change the relay and it only worked for a minute. Is the relay bad now or just the blower?
Walter Martinez: rich ..i got a 97 WYNDSTAR MINI VAN AND IT DOES BLOW JUST COLD AIRE,, I NEED IT TO HAVE THE HEATER BUT IT JUST BLOWS COLD AIRE ,,AND THE AC COMPRESOR TURNS ON AND OFF ,,,,I DID TRAVELED FROM NORTH DAKOTA FREZING ,THE INSIDE OF THE VAN WINDOWS FROSTED IAND I HAD TO SCRAPE THE ICE THE FRONT WINDSHIELD TO BE ABLE TO SEE MANY TIMES FOR 24 HOURS ,,AND I NEED TO GO BACK ,,,I WOULD APRECIATED IT IF YOU DO TAKE THE TIME TO READ MY CASE ,,I NEED YOUR ADVICE THANK YOU MUCH
Troy Chatman: I fuks wit YOU!!..tube!
yJoshua Birtch: Sorry, you are correct. You are measuring current. DC; Direct current! The voltmeter works by measuring the current through a fixed resistor, which, according to ohms law is proportional to the voltage across the resistor. An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire...which is what you were checking for.
Gary Gillon: Excellent video but I noticed the same as Thom you used incorrect terms voltage and current but otherwise an excellent troubleshooting video and very thorough thanks.
Thom Adams: When your doing checks with your meter, your terminology is not right, your checking for voltage not current. Current is a value that you get while operating an electrical object by applying voltage to it.
Stu Bags: Man you sound like peter griffin!! Thanks for the vid
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.
Thomas 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!
A Dill: Why are you going backwards you had power as far as the motor?
