1995 k5 BLAZER/TAHOE
I have an ABS light that keeps coming on.
here are symptoms:
abs light comes on
loss of power/falls on its face
sometimes dies, but always turns right back over.
speedometer stops working
ALL AT ONCE

I am clueless and would like some experienced insight.

 

Start by removing and cleaning the VSS sensor located in the back of the transfer case.

 

By chance do you know what the black boxes are, on the out side of the frame rail, inside the front wheel wells? my tires are rubbing on them and thinking that might do it. Get new ones and relocate them.

 

Can you snap a pic of what you are talking about and post it?
