The same thing has happened to me in my 2014 5.3L, 150K+. Drove all day without issue but when at a mile away from my house, the fans started up at very high speed. The internal temp gauge was no where near midway and outside temp was about 40 degrees F. I unplugged the negative battery terminal for a second (10mm socket) which killed the fans immediately. She started up just fine this morning with no residual issues. I'm keeping a 10mm closed end wrench in the center console just in case it happens again.

 

I hope this helps!

Iam having a problem with my 2014 Silverado LTZ with the fan staying on full speed (sometimes ) when I shut the truck off. I can hit the key again and the fan will stop. I took it to the shop and they told me that it was my thermostat.  That just dont sound rite to me it's not running hot or above 210 as normal. Any information  would be great. Thanks

The other thing is watch the volt gauge. Mine is dropping to almost 10/11 when stopped. We checked the air filter so I unplugged the MAF. I was able to get my fans to stop running at high speed once I cycled the key on and off a couple time and wiggled the MAF back and forth. Hopefully it stays working properly! I have a 2014 Silverado with 79k miles. 

I am having the same problem on my 2014 Chevy Silverado LT. when I crank the truck up my fans come on full blast and stay running full blast until I reach my destination and continue to run for another 10 minutes after I cut off the engine???!! I need some answer if you may have any? Seeing you’ve had the same issue

I just installed HID’S in my 2014 GMC Sierra slt 5.3, I unplugged the Mass air flow sensor to get airbox out and plugged it back in to start up got fans running and check engine light on ??    It’s been sitting for 3 hours during the light install . Now it runs with fans on and engine light on ? I turned it off cause I didn’t want to drive it

I have a 2014 Silverado LTZ and I am having the same issue. It started about 2 months ago, the fan just runs constantly and I cannot figure out why.

Last summer, I had to have the A/C  compressor replaced and 2 days later, again blowing hot air. So the dealership had to replace it again.  In Jan, my son found a small package containing the seals for one of the compressor lines ... just sitting up on the ledge right by the windshield wipers.    And guess what.... the A/C is not working again!!!

 

I would love to be able to just add those seals to the compressor line and switch out a fan relay.... that would be optimal for me.

Anyone have any suggestions?

I am currently having the same problem. The truck hasn’t even run you turn it on and the fans are going full speed. I thought maybe running the ac was the problem but it doesn’t appear to be. The fans stay on after the truck is turned off. I was wondering if it is the fan clutch? Any input would be great! Thank you

Welcome to the site.

 

You do not have clutch fans on the K2's, they are electric.

 

This may help you.

I unhooked the battery for like 30 min and it didn’t kick back on so maybe it reset. Will see in the time coming! Thank you for your input and will definitely look at that!

WYes I had some strange issues with the cooling fan on my old 2014 5.3. The fan would come on at unexpected times and run for a good bit of time when i knew it was totally unneeded. Was intermittent and the dealer said waaaiiiiiit for it................. NORMAL

This just started on my truck.  Twice in a week. 15 Sierra with 218k.  Ive had LEDs for 2 years and have never adjusted the MAF so I do not think it is related to either of those.  I could possibly see thermostat issue but there has to be a better way to let know there is an issue than leave the cooling fans on.  
 I’ll post if I find the root cause.

    • Declaring victory would upset the demons that possess this Blazer, so I won't. But I did make progress today--after it put up a fight. Always a fight.   I had the day off so I spent the morning cleaning up the shop and I thought I'd get ahead of things by filling the cooling system in prep for the final part I needed to arrive: the driver's side knock sensor. Glug, glug, glug....and then the unmistakable sound of liquid hitting the shop floor. It induces the same chagrin when the sonar and targeting laser temporarily malfunction during a late night bladder evacuation over the toilet with the bathroom light off. D'OH!!! That made a mess...   Oh, hey, that knock sensor I removed? It threads into a wet port. Who knew?! Learn something new every day. Put a pin in that chore, I'll fill it the rest of the way later.   The knock sensor arrived at about 1pm. I threaded it in, connected the wire, filled up the coolant, checked for leaks, and... drumroll.... fingers crossed for a perfect start, excellent timing, model fuel trims, and ...no squeaks... Here goes.....   No, it didn't start. At all. I cranked it a few times and it wasn't sounding good. Furthermore, I heard leaking again. Jesus H Tapdancing Christ, stop leaking all over the dang floor. This time I had accidentally overfilled the coolant reservoir and the churn of the water pump via cranking caused a bit to burp out. Ok, just, breathe... Put the flamethrower down. Dang thing wouldn't burn anyway, leaks too much...   Did you know the rotation of a round crank sensor in a round hole, matters? I do now. Took me about half hour to retrace steps and realize what I had done. Then it started right up.   No squeaks. The squeak was the old balancer.   Once it entered closed loop, fuel trims are dead on, hovering right around zero at idle. No more -30%. I'll credit the injector rebuild on that one.   Timing? I think there's an OBD 1.5 translation error with my Actron scanner. It's anywhere from -20 to -30 at idle, sometimes as high as -40 cruising. Sorry, the engine just isn't running that smoothly at -40 degrees ignition advance. It's just not. It's smooth all through the rev range and has decent power. I'm going to have to trust the seat of my pants on this one.   The new exhaust is very quiet. The old catalytic converter? Not melted, but definitely not healthy. Rains glitter when you turn it on its end...all the precious metal is flaking out. Once the new exhaust system burned in/smoked off a bit, the engine's exhaust smell is normal again. Not that I'd recommend going around huffing car exhaust, but, you know what I mean?   One problem to correct. The new exhaust has the opposite problem of the old spliced up exhaust. It wants to hit the floor where the old one wanted to rest on the cross member. Happy medium, please? Still noodling on that one, need to look at how I can adjust some hangers.   I don't know what's next. On one hand I want to run away from this thing as far and as fast as I can -- there have been a lot of NOT fun moments. On the other, now that it kinda drives nice, maybe drive it around for a little bit?   Shhh... it's not currently dripping oil all over the floor. I can see just a little wet at the bottom of the timing cover where it meets the oil pan seal. It's not dripping multiple drops with every ignition cycle, in fact, after some driving this evening it has yet to even form a drop that could drip off yet. But the weekend is young... I fully expect this could turn into Exxon Valdez by Sunday. Because this Blazer hates me. LOL.      
    • About that:   Once upon a time in a land far far away lived a car company that was shy about taking your money and wanted to be sure that they gave you more that you asked for so that you'd come back. No really, not a fairytale. 😱   But after the field got thinned out enough to limit the competition it seemed good enough to give you only what you asked for. Fair enough I say but in such a market you have to give something the others are not or they go to the one who does. Gimmicks or glitz. Oh, fins and chrome. Yea, shinny crow like cars. Yum.    Field narrows a bit more and 'brand loyalty' becomes a thing and the minute it does they start thinking to themselves, "Could we make more money if we gave them less than they expect and they will hang in there for brand and comfort with the known?" They gave it a try and da*n, it worked!!    Well, what if we teach them, groom them into believing that less is "Normal" and cut some more corners. Will that work? Oh heck yea!    🤔 I wonder, can we give then WAY less than they expect and make them mad enough to spit nails and STILL get them to pay up? Sure, if we get everyone else to do the same so that the choice is less or nothing at all. How would be do that? Platform sharing.  What a concept, right?  Steal like there is no tomorrow and it's legal too!    Truth is no one is going to give up driving, not for very long. The Gen Z crowd is fine with it and will be as long as someone not Gen Z will haul them around. At some point we all die.    Economic voting only works if you cast a NO vote now and again and enough of them to get dumb and dumber to wise up. Well, that's how I was taught anyway. And it should have worked. Would have worked. But the Bail out!!   Look, you have another choice if  you take that bag off your head. If the dumb it down to some predetermined expectation of how John Q Public will use it the, that is under design it to failure they you use it to a lower stress mode. D'ho!    A 1950 Royal Enfield Bullet 500 will go anywhere a Suzuki Hayabusa will and for just as long. But you will have to treat it for what it is and not for what you wish it was. 
    • Maybe I was just too unlucky, but I had nothing but bad luck with Bridgestones. Out of 3 sets, they all started losing a lot of air when they got down to about 1/2 tread life, and at that point also wet traction suffered more than it should have. Also, the only tire I ever had in my 60 years of driving that had a side wall blow out was a Bridgestone.   I'm currently running Goodyear Wrangler Workhorse AT and am very happy with them.   
    • maybe when the trip is over, check all the other joints in the front end, like all the ball joints, tie rods, pitman & idler arms, etc...
    • Thks, and actually it was my bad, because here in this post there is someone showing the correct wire position as well. My bad... But thank you a lot with the help as well. I was able to find and buy a 10 channel VPM that came from a sister silverado of mine. The same year, same mode, same trim, same everything. 2022 Silverado 1500 LTD LTZ (pre-refresh). I also found to buy just the bottom mirror part that has the cameras, so way cheap than the full mirror. + a used front camera. I did test everything together, cameras, cables and the VPM.... everything worked EXCEPT my original Bed camera and the backup grid lines. I think the reason is because now I need to do the VPM reprogram. I sent a msg White Automotive & Media Service to confirm that it is the problem and that they can do it service for me case.   Once I get it 100% done I will post here result....
