Hi..I have a 2006 Sequoia 4x4 SR5 Ithe car say 4hi/4lo on the instrument panel...how do I engage her into 2wd. I have no need for 4wd in the city. I have presssed the 2wd button when car is in neutral...and waited 5 mins...it just blinks...but the 4hi/lo doest go away.. Someone told me after 5mins driver her and swerve left to right..something about its stuck. Please help..if pictures are available that would be awesome.

Four wheel drive actuator may me at fault, try park the truck on a slick surface like wet grass, set it in neutral and activate 4hi and 4lo back to 2wd a few times, if doesn't help try tapping on motor actuator located on transfer case while someone activates selector, park surface must be as level as possible, a good tip is to activate your four wheel drive once every few months to avoid it freezing up.If nothing helps then it needs to be diagnos by a tech. good luck

THE TRANSFER CASE MOTOR IS ONLY FOR 4WD LOW. That would have never been the problem as soon as you confirmed it shifted into 4wd Low. 2wd and 4 Hi work off of vacuum. You may have one or two issues. A vacuum leak up by the front axle that engages the 4wd HI or the sensors on the transfer case.

You have to put the truck in neutral first then switch the 4hi and don't use the auto select. If it still won't switch you may have damaged the servo and need to replace it. Or worse damaged the transfer case. So try in neutral first and hope that works.

Engaging from 2WD - 4HI/Lo requires movement of the vehicle. very low speed under 5mph, push button should engage. the vehicle has to be moving.

Check the fuse to the 4x4, if the fuse is good then check the 4x4 electric motor actuator on the transfer case. You should hear it work from 2wd, 4hi to 4low and back to 2wd with the push of the switch. if you don't hear it working then check the wire harness at the actuator motor, look for any damages like corrosion or cracked wire connector clips. If the 4x4 actuator is working on the transfer case, then the front hub 4x4 actuator may have gone bad and that's located on the front differential. It's common for the clip there to corrode and break and is an easy fix with a new collar pin, at worst it's the diaphragm on the vacuum actuator that is located under the battery tray. There is a vacuum switch on the top of the transfer case, driver side but when that fails, your front hub stay's locked in the on position. Good luck and keep me posted and hope it's a simple fuse that has gone bad. You can pick up all these parts at Auto Zone or Parts Source and they will have the step by step instructions for you to get the job done with common tools.

If they are blinking I believe it means that there are fault codes present in the pcm. You need to get the computer scaned to see if there are an codes present. If you live near an Autozone or Checker autoparts they can scan it for free.

what causes the 4wd to kick in when you have it in 2wd

your doing it right but your accuater is bad 59.00 auto zone easy install

sounds like little motor that engages the 4x4 on the transfer case gave up the ghost replace and it should be fine.

It is somewhat Normal Depending on how Loud the Clunking is. This is a Common Complaint on the Chevy 4x4's. I have verified this through the Dealerships here in Oklahoma and they all say the Same thing But, I am with you, They should go into 4x4 without that Clunk for as much as we pay for them.
