Chevy Colorado: No Blower Motor - Parts Cannon FAIL

In this video we have a look at a customers 2012 Chevy Colorado that has had the parts cannon unloaded at with an attempt to fix the blower motor. Now it's my turn to see if we can figure out the real problem.

[@Cujo71321]

In 1974, I was working as the electrical tech at a Chevrolet dealership in Houston, Texas. We had a customer bring in a 1968 Chevy Nova with the windshield wipers staying on all of the time with the key on. Quick testing showed that the system always had power with the key on (normal) and the ground circuit went through the two-speed wiper switch in the dash. High speed was a straight ground signal and low speed went through a resistor and cut the signal by half. The problem was that the wiper motor was insulated internally so as not to have a ground except through the switch in the dash, and it had grounded internally and was thus able to work as long as there was power going to it, as with the "key on" position. I told the customer that he needed a wiper motor. His response was that I was lying to him because he knew his wiper motor was good. He said I was trying to rip him off because the wiper motor was obviously okay considering it was working all of the time with the key on, so it must just be a cheap switch problem. He refused the repair and left to fix it himself. I wonder how many parts he threw at it before he finally bit the bullet and bought a new wiper motor? Unless you understand how a system works, you cannot diagnose it. Good work, Eric O.

[@blueoval250]

I’d guess he just put a switch on it and called it done.

[@oliver_klozoff]

If he knew how to fix it why did he bring it to you in the first place right?

[@COBRO98]

But how did you determine the motor itself as the fault, that it had self-grounded internally? Sounds to me like you guessed at the problem & the customer felt the same. The resistor could've failed, could have had a short to ground in the wiring(s) leaving the wiper motor stuck in high-mode.. it doesn't matter how many times you've seen a problem or how well you understand the system if you can't prove the fault.. for every motor that goes bad there's 50 switches that went bad first.. what I would've done in that situation is plugged in a new wiper motor and shown the customer that it now has 2 speeds again, would've taken 2 minutes as everything on cars was easily accessible in 1968

[@oliver_klozoff]

@@COBRO98 well testing if a motor is shorted the ground internally is fairly simple.

[@Cujo71321]

@@COBRO98, please remember that this was 1974, and the vehicle was a 1968 Nova. The process was a simple and straightforward approach. You turn the key on and the circuit is designed to send power from the ignition through the wiper fuse to the wiper motor constantly. The factory designed the circuit to have no external ground at the motor, but rather, to have the ground circuit go to the switch to find ground (The switch itself was grounded by the metal dash it was mounted in). If you unplug the wiper motor with the key on and the wiper running, you can test both sides of the circuit at the plug. There was a constant switched 12 volts on the power side of the plug, and testing the ground side of the plug (which goes to the switch) showed no ground at all with the switch in the "off" position, and full ground in the "hi" position, and half ground in the "low" position. To verify the problem was an internal ground issue, I simply jumped power back to the power position of the motor while not hooking up any external ground. The motor would run as long as there was power going to it. Since the circuit is designed to work using the wiper switch as the ground side of the circuit, and I was a GM-certified tech, and I had schematics and an understanding of how and why it worked, I was able to come up with the proper diagnosis.

The other shop may have made all the money, but you made a loyal customer. You fixed it for less money than the other shop failed to fix it.

[@nickg9021]

@thermalreboot Probably not, unfortunately . People are exceptionally resilient in their stupidity and most customers will continue to use an incompetent repair guy just because he's "their guy". Eric's right ... the guy who changed the blower motor tested for power AT THE MOTOR and found it there, so he assumed the motor was faulty. Didn't know how the circuit was supposed to work . Even so , he didn't bother to check for the other half of the circuit , the return to ground. That "mechanic" should stick to topping off windshield washer bottles .

But if the customer himself took it to Eric he get's to see how much he paid for failure and how much less he paid for success. The video was something like 25 minutes long, I'm guessing the work took a little longer due to Eric moving and setting up cameras, but still, less than an hour to find and fix. That would make any customer take notice.

This is what happened at other shop. No trouble shooting skills but they can chage out parts real good.

[@spelunkerd]

Likewise, agreed. There's a depth to Eric's videos, most of which goes well over the crowd's head. For example in this case he put the motor connector back together and quickly checked it again, verifying that the electrical connections at that point are fine. He does this so smoothly, efficiently, and easily that people think the task is easy. A lot of thought goes into his work flow, and to really understand people need to pause the video as they follow the story and decide what they would do next. Passively following along is not enough.

[@sumduma55]

Both of you, just keep trying. I'm gonna say this in the dumbest way possible... there was a cartoon I saw when I was young where the main character (i think it was Charlie Brown) went to France and couldn't speak the language. After several months staying there in some exchange program, he was lamenting about how much of a loser he was when he noticed the château he was staying at was on fire. He ran panicked to tell the neighbors and get help when he realized he was speaking and understanding French fluently as this was happening. What I'm getting at is that even though it doesn't immediately click, you are still absorbing knowledge and one day you will realize it wasn't near as bad as you thought. Just don't shy away from trying so you don't stop that in its tracks.

[@KA9DSL]

Weird place for a return ground, glad you caught it. Some mechanics have no visual concept of electrical wiring, glad you do!

[@spelunkerd]

For those who were confused at about 3:00, the brown wire looks black on the video, it delivers power to the motor. The other wire is orange, not brown. That orange wire is downstream of the motor so grounding it causes the motor to run. My jaw dropped at 4:35 when it continued working after ground was removed from the orange wire on the blower resistor connector. There's an upstream T connection between only the orange wire and the switch. Presumably the switch was resting on the high speed setting at that time, allowing the motor to find ground through a tenuous connection after the charge on that wire was drained down. I find it amazing guys can understand this without a wiring diagram, but I guess if you've seen this often enough, memory of other diagrams comes to play.

[@unimportant5122]

A motor draws a large startup current after which the current goes way down during normal operation. The faulty ground connection couldn't carry that large startup current. Once it was started by manually grounding the wire with his probe it kept running because the faulty ground connection could still carry the lower operating current.

What happens when the doctor is confronted with something they don't see every day, like Ebola, or Lyme disease, or the Marburg virus?

Been fighting a 2008 Colorado for 3 years, 2 blower motors, 3 resistors, 1 switch, and rewired the ground on the fender about a year ago. Guess what heater fan is out again 😢

Great video of what should be such an easy diagnosis rather than an exercise in parts guessing. The ground path is neglected so often.
