#3129 of 3449 1995 Chevy Blazer 4WD not engaging by chevyride22 Jan 31, 2008 (7:22 am)
My 1995 Chevy S-10 Blazer will not go into 4WD. The 4WD is electonic with a button for 2H, 4H, and 4L. When you hit the 4H button, the light comes on and you can hear the relay in the control module in the dash activate. I can also hear the tranfer case motor engage. The drive shaft to the front differential is also engaged. I have replaced the vacuum switch on top of the transfer case (ball inside was sticking). I am not getting vacuum to the vacuum diaphram actuator located under the battery tray. This is what engages the 4WD. I have checked all vacuum hoses for breaks or kinks. Where does the vacuum hose go after it leaves the actuator? It appears to go in behind the motor on the back leftside as you face the motor, but cannot see where it connects. Does anyone have or know where I can get electrical and vacuum diagrams of the 4WD system? Are there any other items that can be checked? Thanks.

Replying to: chevyride22 (Jan 31, 2008 7:22 am) I'm wondering if you could hook up vacuum temporarily to that actuator to see what happens. You could hook up a vacuum line to a known vacuum source and use an aquarium valve to turn it on and off in the passenger compartment. A bit of a hassle but it would tell you the problem area.

Replying to: chevyride22 (Jan 31, 2008 7:22 am) hi you are right it does go in the back of the motor on the left as you look at the motor.get up on the motor and you will see it.also get someone to engage the 4x4 while you put your hand under the battery tray and see if the pump does work you will feel it moving if it does the transfercase motor is not working i had to change mine
