So I have 2001 chevy s10 blazer. Since I bought it the 4 wheel drive hasn't worked. I was able to put it 4 wheel drive and the transfer case would engage but the front tires wouldn't spin. Now I don't have the option to put it in 4 high or 4 low. Also my abs and e-brake come on and off randomly. Just need some pointers to help me get my 4 wheel drive to work and the lights to stop coming on

 

First, what is more important to you, the 4wd issue or the ABS E-brake issue??
Could be separate but equal issues..

I, too issues with my 4wd not working and the ABS e-brake issue, however, in my case I know what is wrong and will be repairing one of the issues soon..

So, what would you like to tackle first??

 

I would like to get my 4 wheel drive fixed first

 

What do you mean I don't have the option of 4 hi or 4 lo??

Do you have the three or 4 button on the dash??

 

Yes I have the buttons on the dash but they are not lit up and when I push them nothing happens

 

If you don't hear the encoder motor engage when switching from 2hi to any 4wd positions, and have no lights on the switches, sounds like no power or the TCCM is bad.

Do you have the 3 button, part time 4wd, or the 4 button AWD system??

 

I have the 3 button option

 

It could be your 3 button dash switch. If the lights are all out and when you switch from 2hi to 4hi and don't hear anything, then maybe your dash switch is bad.

Still could be the TCCM or not getting any power.

Have you checked your fuses??

 

Replace switch cheap fix they have them at part stores then check vac lines under battery they might have come loose. I replaceds vac lines or they came unplugged mine did everything works great now try that

 

I will give it a try thank you guys!
