2001 Chevy suburban won’t shift into 4wd

[@demetriopuente1258]

3/15/2021 I just got stuck in Fort Collins Co in 2ft snow. My suburban was doing great, Then i lost 4x4, called for a tow truck never showed......Anyhow i was stuck for hours no gears noo shifting no 4x4. I searched forums and the web. Your video got me unstuck and home THANK YOU THANK YOU

[@str8burbn]

Yeah sounds like you were having fun lol. Glad it worked out for you

[@tylerthompson1652]

Thank you for making this. Fixed my 4wd

[@sunnyrooprai3731]

Hey Guys, so I live in Calgary Alberta......With this said, our winters get frigidly cold -20C common......my 4wd service comes on/fuse blows/lights on selector switch goes out. Nothing works...found a write up - not sure if its from GM directly. But it states, if your 20amp ATC fuse keeps blowing, but Encoder @ T-case works......front diff actuator works. You're getting get grounds.....good voltage at connectors....( Bench test front actuator ) and it works.......and there is no code for TCCM ( Transfer Case Control Module ) ....it is the 1640 connection - they used 18 gauge wire from factory but during colder than normal ambient temps - it will spike in amps and blow the fuse....The easy fix is replace with 25amp fuse. OR replace the Orange wire - with 16Awg. DONT GO SPLURGE ON PARTS BEFORE YOU DO ALL YOUR CHECKS!!!!

Thanks for the info on this this helps a lot

[@domingomillan7578]

Thanks for the heads up on the fuse it was actually blown I replaced it 👍

[@str8burbn]

Nice glad it was just a fuse

[@genesisobadiah]

You the best! I plugged out the 20A and reinstalled it with the engine off. Turned it back on it switched for me. Also note, I had 15A yellow in the 20A for some reason. I switched it anyway and it came on. I will be buying a new electrical pierce set for my truck circuit. Thanks again

[@str8burbn]

No problem

[@roggadat5114]

I was having the same problem. Service 4wd came on. Ordered a cheap selector from Amazon and I switched it out. It fixed the problem. 🤙🏾

[@str8burbn]

Nice and I plan on getting a new selector as those go out more often and their cheap to replace 😂

[@kikcsomeass]

Thank you. It really really help. Its only on auto or 2 hi. And sounds weird. I will check fluids and other things but now it works. I see your video helps a lot of people. Thank you again. You have made a lot of people very happy. Make more videos

[@jakevawdrey9691]

I had the same issue with my 2001 1500 Silverado. Unplugged the 4x4 actuator plugged back in and it fixed the problem. Lasted another year until I sold

[@str8burbn]

Sometimes it’s as simple as a reset and it’s fixed. I hope this fixed mine but if not theirs some cheap parts I can replace before replacing the shift motors.

[@cobyporschifer221]

SWEET 👍 Thanks gor info. GOOD VIBES

[@MrFireman164]

Thanks got me out of being stuck in 4 high

[@str8burbn]

No problem

[@allsmiles7490]

Thanks man made it a quick and easy fix for me.

[@str8burbn]

Hopefully it worked mine just started acting up again I’m thinking of converting to manual couple hundred and some parts off older Chevy

[@yusmelpelaez2897]

Thanks nice and helpful video I tried tomorrow morning

[@jasonhood9254]

Its not the switch or any other components from 4wheel drive system and its not that ground wire he shows it the wiring harness for the for wheel drive system trac down the ground wire in the harness and fix it happens to all of them or replace wiring harness for transfer case

[@alteredstateskustom]

Here’s a weird situation. My switch has been acting up for years. It would switch from auto to 4 long when the truck was shut off The indicator lights wouldn’t always work But 4x4 always did. So I just left it. I knew I’d have to change it eventually Yesterday I was in 2wd and it wouldn’t go into 4x4 at all. I checked the fuses and grounds everything was good. I knew it was the bad switch. I went and picked up a replacement and installed it. Same problem. The lights would light up when you start the truck. But went out and wouldn’t let you select 4x4 I was puzzled because it worked fine the day before. The only thing I did differently was disconnect the battery while I installed a led lightbar I didn’t think it could be related. But I tried it anyways. I disconnected the negative terminal and cleaned it. After about 5 minutes I reinstalled it and BOOM The switch works as it should I just thought I’d share my experience I’m not saying that’s what did it for sure. But it’s working fine now. 🤞

[@str8burbn]

Sometimes a reset is all it takes

[@marvinchevytahoe]

The help allot thank you I have the same problems

[@eworks9828]

2000 tahoe same problem. I just cleared the code with the bluedriver scanner and it worked immediately.

[@str8burbn]

[@natejosich]

[@natejosich]

[@str8burbn]

That’s nice when it’s simple

[@Smokinstrainstation88]

I just had my abs module changed now i have a service 4 wheel drive code and i cant switch it to anything the lights in the switch dint even turn on an everything was fine worked perfectly until i sent it in to to get the abs fixed now i cant figure it out

[@Zero12731]

Did u solve it????

[@stephengalante2973]

its probably the actuator on the front diff going bad \

[@MrRICK244808]

Hello everyone I had the front diff rebuilt because it was making bearing noise very bad so now I try to but it on 4 low and I hear it go in but the it try going up a hill only my rear tires turn not the fronts but when I put it on awd 4x4 it works but I lose power and when im on a flat surface the 4 hi works but once it try going on rock it doesn't work at all does anyone have a problem like this let me know thanks

[@str8burbn]

How’s the transfer case is it locking in as well or just the front diff?

[@MrRICK244808]

Hello front diff only locks with 4WD AUTO only but with 4 low will not work the gearcase electric actuator makes a loud noise then works but then when I roll forward only rears work there is no grinding or anything at all

[@str8burbn]

Maybe it’s time to rebuild your t case if this were me I’d manually shift the t case in 4 hi with the actuator off the case but still plugged in the harness than hit the 4hi button and see what happens than same with 4 low

[@thaddeusmorrisonjr317]

My problem is the opposite

[@alfonso80689]

Thanks

[@str8burbn]

You bet
