This question refers to the General Motors S10/Jimmy model lines in 4WD. This issue is most likely related and due to a transfer case problem. It should be diagnosed and checked as soon as possibly to avoid further damage and or loss of gears.
Push the button that says 4WD, either Hi or Low, depending on which one you want. Push the button that says 4WD, either Hi or Low, depending on which one you want.
i have a 94 late model s10 blazer and i am having the same problem, and it is either the vacume hoses are cracked/ leaking, or your 4wd actuator is dead, the best way to fix this problem is at 4x4posilock.com they have a kit that includes everything to convert your truck from that stupid electronic 4wd, to a cable operated switch, which allows you to 2wd hi 4wd hi, 2wd lo and 4wd lo
It could be your TCCM. Disconnect your negative terminal on your battery for 30 minutes to reset your TCCM and see if that works.
Most vehicles need to be stooped and in neutral before they will engage the the 4WD in low.
Yes, you can go from 2hi to 4 hi on the go.
Fo four-hi just pull the transfer shift lefer back you should NOT need to push in the button on the lever. For four-low PUSH and hold the button, on mine I have to turn the engine off and pull the transfer shift lever to the four-low position.
Trans in park or neutral, 1st click up on the 4wd shifter is 4 wheel hi, 2 is neutral, 3 is 4 wheel low, 4 is 2 wheel low
I believe the 4wd unit (or transfer case) must be in gear. If your vehicle has an owners manual, the answer is there. Also, there should be some indication, via a sticker on the dash or a diagram engraved directly on the 4wd shift lever, of which way to move the shift lever to engage it with a particular gear. For instance, on some vehicles, if the 4wd shift lever is all the way forward it will be in 2wd HI. All the way back might be 4wd HI. And half way back might be 4wd low.
You can but you will destroy the compressor and send metal junk all through the ac system. The hi and low pressure switches are there for a reason.
hi, the filter is under the truck . near drivers side in front of rear wheel on the frame.
I actually had to hit the 4WD shifter to get it from 4WD HI to OFF.
The headlights are a separate circuit from the others. Check the bulbs, headlight switch, Hi/Low beam switch and depending what year you have check the fuses.
