I hate it when my beer falls off the fender while my wife is yelling at me. And to think of it, that dayam kid's got some eye color that I've never seen in my family. You kill me. Great diagnostics and great entertainment.
Question for YOU Eric-Is it Chrysler products you find that Prodemand is incorrect on mostly
Reason for asking-Prodemand and ALLDATA non OE color diagrams are made by the same company, Valley Forge. ALLDATA has the non OE diagram for at least one option but they often just pick one of three or four and hope it's yours.
I work for ALLDATA, nothing to do with content, and I go to the OE Chrysler site often in hopes of getting and accurate diagram and wouldn't you know it, no dice. Chrysler's wiring diagrams and connector views more often than not don't match the vehicle even by VIN. One of a couple of other manufacturers that seem to care more about selling vehicles than producing actual good service info.
I tried to use Prodemand many times for months at a time and never could get used to their disorganized method of information organization. It seemed like most of their info was just thrown all over the place with no logical order. Cost me too much money flat rate so as shop foreman I got it yanked and back to ALLDATA.

Working on a friends boat with a 5. 0 Cheevy in it. We did heads and when it went back together no spark, no injector pulse. The relay that powers both wasn't being grounded by the module so he started pricing modules, however there was also no power going on the other side of the circuit. Even when applying power manually, the computer would not ground the relay. I insisted we find the blown fuse and what caused it first before we started swapping computers. Injector wire got pinched by the spark arrestor shorting to ground and blowing the fuse. The module sensed a problem and shut off the control for the relay. Once the wire was fixed and the injector was replaced the computer was happy and started working perfectly. Now the boat is running. I learned that kind of skill on the U-tube and mostly from Mr. O.

Love the diatribe, because it's true. Now then, YOU are not the same as others. My 1999 Tahoe, blower resistor went. I know it. worked on LOW and HIGH only. No 'smarts'. I'm putting in a blower resistor period. Yep. worked. When I was talking to the local garage they were Oh, we have to do a bunch of testing, yada, yada, it's going to be $250parts. I said What do you THINK it is. The mechanic (not the boss man saying all this diagnostic bs) says It's the blower resistor. Get one from O, O, O O'Rileys and put it in. It's a B! tch of a job because there is ZERO space, but the only thing it can be is a blower resistor on that old thing. Never saw a boss so pissed at losing $250 of profit in my life, because it was a 15 minute job. The mechanic opened his own shop and is very trustworthy.

Working with heavy machinery and such, fighting the overdone/engineered electrical systems, we have relays modified with LEDs or 12 volt lights to indicate which relay legs have power or ground. Break Out boxes for monitoring systems. All good but best is twisting the arm of the software guys to show us troubling methods they know but didnt want to share until late night trouble shooting efforts, and very early morning appearance orders from above big Bosses to fix systems. Also lap top computers were supplied with individual system trouble shooting for in vehicle maintenance and software trouble shooting, the old saying from software programmers doesnt hold water anymore. Like it worked in the lab doesn't fly anymore. : Ten-4

Of course you put in a blower motor. THEN you diagnose- because Einstein the tech effed up.
Who pays for the motor YOU
This ain't happening at South Main but for damn sure it's happening in the next town over. Maybe even in your friendly Jeep dealer.
Older mechanics know this, we've all seen it- the boss TOLD YOU to do it
DIY takes out the wiper relay to fix the HVAC blower on his wife's Explorer. it's hot!
Then it storms
The shorted blower motor finally burns up the relay DIY took from the wipers and now she has no wipers and no defroster
Some people could get killed
And do

I'm sure that is a brushless blower motor. We started using these in Freightliners when Daimler bought Chrysler. They have a dedicated power and ground and a signal wire that received a PWM signal from the HVAC control. On the Freightliner M2, a quick test was to check at the motor for power and ground. If that was good, you could ground the signal wire and the blower would operate on high. However, on the Cascadia (class 8 truck) it used the same blower motor with 2 signal wires. I never got around to seeing if you could do a similar test on it.

If you haven't bought a relay at a parts store in a while folks, get ready to be shocked. A very basic, ordinary relay for an A/C compressor cost me $18. I guess that so many people are ordering big parts online these days that the parts stores are gouging on parts that people need right now. If they would offer good quality major parts at a decent price they wouldn't be in this mess, but they trained us to believe they were selling us crap at premium prices, so we order online where we may still get crap, but it won't cost so much.

One of our Transit Vans at work lost its mind the other day. We were driving it and the cross traffic warning failed came up, the blind spot warning failed came up, the climate control panel went dark, the driver's window wouldn't work the drivers unlock buttons wouldn't work, passenger side window and unlock buttons work, remote fob wouldn't unlock or lock the doors and all this was intermittent. Took it to our transportation department, and they said we will send it to the dealer. So I'm expecting we won't see it for a couple of months

Funny how over the weekend guy calls me saying car won’t start after he took all fuses out to check a bad fuse for lighter/charger. I open fuse box and he swapped every fuse out with a TEMU fuse. Every fuse he replaced was blown and he thru the old ones away without checking. All over fuses from TEMU. He was upset at bill for holiday service fee but atleast car is running and the rest of the fuses he had left he got rid of the them

When I left the my last dealership which was ironically who you buy gm parts from. Most of the guys just shot gun parts at everything with out diag. I've have been handed so many parts that have been opened and clearly were plugged in to see if it fixed the vehicle. I see techs asking questions after shot gunning every part at it and it didn't fix it. And it was something supid and the diag would have figured it out

I hear ya Eric! Too many people jump to conclusions without stepping back and thinking for a minute.
Like my 2 guys struggling with a flat tire all day, not noticing the L stamped on the wheel stud.
Or the 4 guys that proudly holding up the entire wiring harness of a tractor saying we need a new one before noticing the generator belt was missing.
Teachable moments.
All you can do is laugh.

So it seems that there are no mechanics per se- they are becoming extinct. Change their name to digitals. Nothing operates mechanically, even the fan system that blows air into the cabin. Even a brake job requires the assistance of a gee-whiz tech gadget. No wonder mechanics are slowly becoming dinosaurs - who would even want to be All backed by Fiat quality. what could go wrong

I'd love to know what the bill was to the customer for trouble shooting and installing the relay. As an older guy who can get stuck in 1980's pricing, I'm often stunned with costs to repair cars, appliances and other things today. We're all I'm sure shocked at how expensive things are today. Groceries, gas, insurance, parts, etc. Keep up the good work with your excellent content.

Most informative and entertaining videos on all of YT. Been watching for 7 or 8 years.
Love it when you go for a rip around town on a test drive. Know your fan base is world wide but,
how far does your customer base stretch. Avoca only has a couple thousand people, either
every car in town is a broken pos or you've got customers coming from a 100 miles away

Yeah Eric, you're more entertaining than watching politics on TV. I learn enough watching you, but I'm a mechanic used to be a mechanic used to be a pilot. Now I'm just a regular Joe getting old so keep up the laughs. Say hi to the Mrs and I guess the kids are yours. Maybe I don't know. We only seen the girl. Take care. Have a good 4th of July

I called my oldest daughter and asked her to do a DNA test, she immediately called my wife unit and I just found out that the doghouse isn’t really that bad.
Not really. But the wife did suggest that I replace K9 relay. Which tells me that she already watched your video.
Were you in Texas in 1985 Just asking for a friend.

Eric you can never ever please everybody.
My teacher a long time ago said, you can five mechanics and every one will have five different approach to fix the same problem.
Long story long No one person will start there diagnoses the same. But hopefully the outcome is the car is fixed.
15: 10 Hopefully the same week

Any help on a 2011 jeep jk 3. 8 upper raidiator hose swelling up.
Changed radiator cap, thermostat(both Murray's) and used a big bowl syphon technique on uphill incline to remove air.
Puzzled, seems to be a reoccurring thing that used to crack upper radiator neck.
Anyones ideas or help is appreciated.

Eric your shop reminds of a neighborhood shop that is used to hang around from time to time.
The two brothers that owned it have since pasted away and the shop is gone.
I looked on the map it would be about 6 hours to get to your shop from Michigan.
So you are safe from me showing up.

Idk why but it’s always neat when you go into a diagnostic damn near confident you know what’s it’s going to be and then it just completely takes a left turn. It’s like a box of chocolates when you go to test it and have that ah ha moment of O wow it’s not what I thought it was lol
