4WD WON'T ENGAGE

1999 Dodge Ram

Transmission problem
1999 Dodge Ram V8 Four Wheel Drive Automatic 155095 miles

I have a 1999 Dodge 1500 4wd, auto trans. The 4wd won't engage. The indicator light on the dash does not come on. I serviced the front drive shaft last summer and test drove it after installation and it worked then.

Hi: Does the truck have a manual shifter for the 4wd or is it electric?

Hi: I need you to check the linkage to the transfer case to make sure it's working properly. Also, check all vacumn lines to and from the transfer case, axle.

The linkage seems fine. When I put the lever in the 4hi position and give some gas, I can feel the lever move/vibrate. The vacuum line appear okay. There is one large line coming from the front actuator which appears to have been cut and wire-tied with an open end. BTW my 4wd has worked in the past with everything the way it is now. Thanks.

Check to see if there is vacuum at the cut hose. If so, replace it.
