check fuse
i dont have an answer, but my 4wd works, the lights just blink randomly sometimes
Well your 4WD might be going out, it probably wouldn't hurt to get it checked out.
Typically it is because the connector inside the console that electronically switches the 4wd system on is not connected properly...This happened to me...I pulled it out and pushed it back in and the lights went off when in 2wd or Auto 4wd mode...
Well is it actually engaging into 4WD? If so, then you do simply have a problem with the lights. However, if you don't notice the transfer case engage, you may have a problem with either the push button system or the transfer case itself.
My guess is that a vacuum line was disturbed that engages or disengages the 4wd.
make sure that trans is in N if that dont work turn car off then shift to 2wd or 4wd
well first you need to determine if it's actually 4wd. if it is there are 2 things: there might be 4x4 buttons on the dash or you may have a stick shifter to do that. whatever the case, 4wd high is the best one to use. now, how to get there - if you have 3 buttons that say 2HI, 4HI, or 4LO then just press the 4HI or 4LO button, whatever you prefer. almost the same with the shifter, but with the shifter you need to stop the blazer completely and shift from 2wd to the 4wd gear of your choice.
the electric servo and or the switch is bad.could be one or the other. A common problem if not used in some time.
well,, you can start by turning the switch on your dash that says '4wd'
No. 4wd helps with pulling traction. Brakes work exactly the same on a 4wd as a 2wd and the 4wd helps none at all in stopping.
Find some loose gravel, dirt, etc... that you won't get stuck in and stab the throttle to make the tires spin. Try it in 2WD first, then put it in 4WD. You'll pretty much know at that point.
