jobamasux: Thank you for making this video! I was able to diagnose and fix the problem with my heater blower motor! Mine turned out to be a bad connector at the motor! Unfortunately the wire that connects to the blower motor can be bumped by the passengers feet and cause a short! I corrected this by taking some electrical wire and pulling the wire up and wrapping the tape around the motor. wire and connector. This should prevent someones foot from inadvertently striking the wire!
John Walters: My 2006 Chevy Equinox Blower HVAC Blower works then stops for days , then suddenly Starts up again and runs for days, Then after a some period of time Shuts Down, ETC.
Joe Fazzari: This is extremely well done. Thank you for posting this video. It is extremely helpful and complete. Are you a shop teacher? If not you should be.
Paul Webster: You don't address what needs to be repaired/replaced if there is NOT continuity in your very first test of ohms on the Black wire going to the plug to the blower motor. My black wire is slightly melted at the connector and there is high resistance (no continuity).
bert forbes: I have a 2003 camry where the blower motors don't turn on. But when I check the wires at the motor, I have continuity to ground on both wires. No current on the hot wire. I swapped the blower motor relay with horn relay. This changed nothing. I am really not sure of the labelling on fuses and relays.
Paris Nicole: so in ur 1st steps checking blower wire purple/blckstone if u have current it's no good or is it good
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 Balls: Man you sound like peter griffin!! Thanks for the vid
Autostop: buuu ,you dont know what is current what is voltage,all test you did was VOLTAGE testing not current
