4x4 problems - negadave - 01-18-2011
I've got a 97 isuzu rodeo. It's an automatic with a seperate shift lever to put it in and out of 4 wheel.
It has 2 vaccum lines going into this thing under the car to lock and unlock the front hubs.
The problem is the 2wd vaccum line always applies vaccum and the car won't go into 4wd. If i get under the car and switch the vaccum lines around, it goes into 4wd but won't go into 2wheel.
Anybody know what would cause this? I don't feel like crawling under a wet car and switching the hoses around every time i want to go from 2wd-4wd.

Do the lines go into an electric solenoid? If so replace that.

There may also be a VSV (vacuum switching valve) that isn't functioning.
