Possessed Cooling Fan In A Caravan - Mind Of Its Own
video description
At the seminar we were told to never change any customer settings unless absolutely necessary or it was involved in the service process.
Some customers get real triggered when their seat settings, climate control settings, or any of interior adjustments are moved or changed and it can turn a happy customer into a raging or unhappy customer that doesn't come back or gives your business a bad reputation even though the service work was performed flawlessly.

My 2003 Town & Country - I replaced the driver's door window regulator on two separate occasions, but many years apart. After the second replacement on very hot scorching days the window would dislodge and fall into door when lowering window then raising it with button. Every time I would find that the window pin would pop out of the regulator. The metal retaining mechanism would never grip it well enough in hot conditions and it would pop apart. I got pretty good beating the clock each time pulling the door cover off to gain access and pop it back together until the next time. The passenger side front door had a faulty down switch, so only the drivers master switch would lower that window.
I owned the van since 2006 since its purchase as a lease turn in with 30k miles. Two weeks ago the van was totalled when a young girl driving a 1998 TJ Wrangler lost control of her Jeep on a straight away in about 3 to 4 inches of snow. She slid sideways into the path of my son's lane sideways. Boom. She was broadside. Police cited her for the accident. The tow bill with 3 days storage easily exceeded the value of the van, then with 269, 000 miles. The salvage yard only cared if it still had the original catalytic converter. And it did. The cat was worth more than the van, even before the accident. And Eric, it still had the original 41TE transmission! No kidding! Like the van you were in, the headliner had separated and fell away. It looked ungodly, but the van was well maintained, safe and dependable transportation. It was great to load things into it from Home Depot since I didn't care about scratching the interior.
Overall, a great vehicle all the way around. RIP Chrysler Town & Country.
Merry Christmas to you and Mrs. O.

heres a comment for the comment section. im tired of people of judging cuz ooo you can be better than turning wrenches. f that. im tired of the ignorance that goes behind those sayings. watching you and being from nepa the rust belt. the scan tools the electronics behind diagnosing the true art is truly scientific. And! being able to have wife unit( as said from rainman ray) and family still involved with some of your diag. work. is truly amazing. you dont see the same effort and family oriented stuff comming out of a city office cubicle. sorry my rant like your window motor. but its issue i have with todays society. o you own a car shop. not a ceo well. get to work tomarro some one is genius to get you there. that is all. just a rant sorry.

Bummer the scope didn t pan out, I really enjoy the advanced diag videos. With the economy crapping out, people trying to keep cars going longer and the cheap scopes available I think more of us will need the skills and techniques you graciously share. You are a gifted troubleshooter and it is much appreciated. re: the window, I once got trapped outside a possessed Chrystless product that auto locked the doors on me vehicle running, late at night, in a remote location, my cell phone in the truck along with my jacket, me stuck outside wearing a hoodie at about -35f. Obviously survived and still have all my fingers. Putting windows down is now strongly ingrained for me.

Being the outmoded dinosaur that I am, I think back wistfully to the 1960's, when the radiator cooling fan was driven off the engine, by the same belt which operated the water pump pulley. Voila.
Problem solved by old technology. No electric cooling fan, no relays, no sensors. But of course nowadays, we all suffer constantly from the improvements delivered to us
by industries in love with their new whiz bang ways of making life more difficult.
We are told that electric cooling fans always improve fuel economy, but I beg to differ. A Chrysler corporation slant 6 from that era can achieve highway fuel economy in the low to mid 30 mpg range.

Eric, surprised that you didn't mention anything about the recall on that relay. There was a recall on that relay back in the day, I've done a few of them. That's the first time I've heard of that rule about the windows. I always roll the driver's window down when I pull the vehicle into my bay, or if that one doesn't work, a least one of the other windows. Reason being that back in the 90's, there was an alarm system that was very popular then that would automatically lock the doors when you get out and close the door. Got burned a couple of times that way, so I have been rolling down a window ever since, and still do to this day.

we own a dodge journey (2015)- similiar tipm.
ours has two fan relays, 1-for regular driving cycles, and 1- for high speed/ when a/c is on. The 40 to 50amp draw on the cooling fan puts enormous stress on the relay. once a year it cooks the regular relay(stuck On) and fan comes on by itself (engine running or not) and will Not turn off til you unplug the relay or pull the fuse. We now carry a spare in the glovebox. Also, if in a pinch you can put the relay used for high speed in the regular spot to get you home. they are the same part number, at least in ours. I have found this to be one of dodges many design issues

I feel your pain with the power windows. I usually roll the window down to prevent getting locked out. I put the keys o n the bench but unfortunately installing blow n goes I need to turn the ignition switch several times during the install process. After a recent install when the window didn t roll up I had quite the dilemma as the customer was a young mother with two toddlers in the back seat and the temperature was well below freezing and her home was 45 minutes away. I wasted an hour and halve of a roll of duct tape to get them home safely.

Had a '90's Chrysler mini-van, the year we have was a magic number one, it was a great vehicle, until the window regulators were mentioned. One of the dumbest designs I'd ever seen. Cable operated, the cable ran over a radius-ed piece of nylon to make the 90 degree turn. Over time, the cable cuts through it, planned failure, jumbled mess of cable and jammed mechanism. Why not rivet a small pulley wheel at that corner, it'd outlast the vehicle.

In reference to your Autel on old Chyrslers comment - Is anyone good with pre-2007 Chrylsers? I feel like so many things were DRB-III that I've heard many obd setups have had issues doing deeper diag/tests. I've been looking into DRB emulators for older Jeep stuff. I was actually hoping Autel would do more, but your comment in this video just made me realize that so much of those functions must be locked in older mopars to DRBIII.

The thing about the windows makes sense to me now. When I worked at a dealership, we always put the driver window down. It used to be not to take any chance that you would lock the keys in. These days most cars wont let you lock the keys inside, but it's still just habit. Most of what we worked on was newer so there generally wasn't much chance of a window not working, but now that I work on junk, it makes a lot more sense lol

When I saw the heat sink I realized this must be similar to control of a blower motor, with some kind of field effect transistor that adjusts current output based on input from the pcm. It was wise to not incorporate that in a full module, since repair costs would be dramatically higher. Also with high heat output it could damage other sensitive components, so better to mount it by itself near a source of fresh air.

Having a flow chart in your mind, plus experience, makes it look like magic when electrical problems happen by and are fixed without a lot of fuss.
I've said it before that the majority of time in auto repair training class should be on the flow of electrons from control to the component(s) and diagnoses. Without knowing how power flows from control to component, a person is basically flying blind.

Two things: 1) I wish you had shown your rivet gun a little better. 2) You could have explained that the fan relay is an electronic device, using a transistor instead of a magnetic coil and contact points. It's really hard to PWM a mechanical relay, as they can't turn on/off as fast as a transistor. I've seen the exact complaint about staying on with A/C blower motors quite a bit.

Excellent piece of advice, 'never touch a customer's electric windows'. Murphy's law says they're already having trouble with it, or as soon as you open it, or close it, it will break, and you own it.
When they complain about it later it's always best to be able to say in all honesty that you never touched their window controls while you had their vehicle in your shop.
