I replaced my accuator, but it always stays depressed unless I disconnect the vacuum line. And it doesn't go all the way into the 4x4 just makes a mild clanking like its just barely in 4x4
[update] I had to replace the vacuum switch on the transfer case, now the acuator works fine.
I don't know what controls the vacuum. I tried pulling on the cable and I can't pull it far enough to engage the 4x4 either?
I have a 1996 Blazer 4x4 with manual shift 4x4 (not dash button) my differential is not engaging as it should.
The vacuum acuator was bad, replaced. The vacuum switch was bad, replaced. The cable may have been bad, replaced.
I took the cable off at the housing on the differential and removed the housing face plate. I used a pair of vise grips to pull the acuator out to engage the 4x4 but all it would do is grind mildly, all it would do is grind mildly when I had it all
So I have traced the problem to the differential. I cant seem to engage the "collar" for the axles to engage.
I just don't know what to do from there? Any ideas would be appreciated.
TIA it's appreciated.
