ABS and 4X4 connected???

zzrage · 06-07-2007, 09:05 PM

I am having trouble with my 95 blazer. It is currently in 2wd but the light on the dash is lite up on the 4wd hi button. When I push one of the other buttons, 2wd or 4wd low it blinks for a few seconds then lights up the 4wd hi again. Afriend of mine thinks it is tied to me ABS light being on. Any thoughts or comments? Thanks!

when my truck wouldn't shift out of 2hi into 4hi, it did the same thing, and it was because a vacuum line on the vacuum switch that engages the front axle was cut, so I would look at those.

mine was cut/unplugged from the vacuum switch above the distributor on the firewall, but the line runs over under the battery on the passenger side if you need to trace it.

There was a recall for something like that a few years back. On my 96 they replaced the switch and looks like added a different vacum line. It hooks onto a fitting that is mounted next to the coolant resivour. If I remember, it was related to a problem involving the ABS not working when 4x4 was engaged.

Cool I will look tomorrow. I replace the transmission from a 94 and swaped some parts in the pan. While I was doing this Both me and my friend had our arms wedged behind the distributor at some point so maybe I knocked somthin off! Cool will let you know! THANKS!!!
