Hey was just curious, I had to replace the 4x4 Push button switch on the dash, but the 2WD-Hi light comes on like normal but when you push the 4x4 Low or High Buttons Nothing happens or lights up at all or anything. The other switch that I replaced was pretty busted up from the previous owner. I was wondering if there are seperate fuses for the 4-wheel drive system that need to be put back in or checked, and then when those push buttons are pushed they will do the flashing light thing and activate the 4 wheel drive.

Thanks,
Joe

 

There is a fuse. I would check the connections at the TCCM to make sure that there is no corrosion.

 

Is that fuse under the hood? Or is it in the fuse panel that is inside the Blazer?

Since you have not stated what you are driving, I have to assume that your screenname means something. For a 95, it will be the 4wd fuse in the fuse box inside on the driver side.

 

Lol ya i got a `95 Blazer LT

Its not the fuses, where is the TCCM at - Its snowing here and would really like to get the 4x4 working as soon as possible.

Thanks,
