Where sould four wheel drive shift lever be in normal around town driving

I'm assuming your refering to a Chevy S10? There should be a small gear shift lever next to the standard gearshifter marked as 2HI, 4HI, Neutral, 4LO. This is your 2wd/4wd shifter. 2HI is for normal everyday driving as it is only powering 2 wheels for better MPG. 4HI is the same gearing as 2HI but powering all four wheels. This is your 'normal' 4WD setting. 4LO is a set of reduction gears designed for serious 'Off Road' conditions and should not be used on public highways. Your top speed will be Very low in this setting and the engine will be maxed out at full revs to get it.
DO NOT leave this lever in the Neutral position without the park brake ON. This setting completely disconnects the transmission from the wheels regardless of the gear you have selected so it will roll even if you select Park.

Which 4X4 system does yours have ?
Four-Wheel Drive Systems The mechanical-shift 4-wheel drive system consists of the following components:

• Transfer case (For transfer case repair procedures, refer to Section 308-07B ).
• Transfer case shift lever
• Manual locking hubs
• 4x4 indicators
• Shift linkage (hub locks)

The electronic-shift, 4-wheel drive system consists of the following components:

• Transfer case (For transfer case repair procedures, refer to Section 308-07B ).
• Four-wheel drive (4WD) control module (For 4WD control module installation, refer to 4WD control module in this section.)
• Mode select switch (MSS)
• Gearmotor encoder assembly
• Automatic locking hubs (hub locks)
• Pulse vacuum hub lock (PVH) solenoid and vacuum lines

At the risk of going to the offensive, sometimes it's the simplest thing - you ARE putting it in neutral, at a stop, engine running, with the brake pedal pressed, when trying to shift out of 4wd, yes?

2) Check for blown fuse for 4x4 shift module

3)This sounds dumm, but worked on my wife 99. I took it to a school parking lot, put it in reverse, floored it and pulled on the lever and it popped out of 4x4

4) The shift motor is bad. Replace it.

Hope this helps.

go underneath and check all pivot points and slides for rust and seized. Check for dried mud build up if you have been off road. Clean the area around the levers and lubricate all moving points.

Yep! it does sound as if you've lost the proper connection between your engine flywheel and the transmission clutch-plate. That baby is crying for your TLC after being such a faithful trooper all these years.

Then you need to check the linkage underneath the floor where it connects to the transfer case, and make sure it isn't loose or mal-adjusted.

ipresume your talking about a manual gearbox
and you have a seperate lever for four high and four low possibly 2 wheel drive on it as well trouble has to be in smalllever linkage and not engaging properly to solve it move the lever around different positions see do u get drive

On small shift behinde gear lever there is 3 settings. H4 = 4 wheel drive high range, L4 = 4 wheel drive low range, h2 = 2 wheel drive high range. as soon as jou engage to 4 wheel drive a green light on the dash board will appear to indicate that the car is in 4 wheel drive. if not check fuse - check air pipes at front wheels.

Your blazer is equipped with a shift on the fly four wheel drive. That means that at speeds less than fifteen miles per hour you can shift into or out of four wheel drive by simply pushing the four wheel high button. If you wish to shift into four wheel low. Stop, put the transmission into park or neutral, and push the four wheel low button. Same procedure for shifting back out. Never shift into or out of four wheel low while moving. And be careful in four wheel low. At full throttle your still barely moving, you don't want to blow your engine up!

i have the same problem but now it is completely out. i heard of a manual four wheel drive to replace the vaccum system.
