The 4x4 system on a 2003 is not vacuum controlled.
A 1996 Dodge Ram 1500 V-6 engine vacuum diagram can be obtained from most Chrysler dealerships. The vacuum diagram can also be found at most auto-parts stores.
probably a vacuum system leak. Older dodge trucks had the front transaxle engage by a vacuum line. Make sure your pump is working, and that there are no leaks. Then it should engage
If equipped, it is on the top of the transfer case and has four vacuum lines plugged into it.
I would start by checking vacuum lines
There isn't a vacuum pump on a 1500. They are only needed on diesels. The gasoline engine makes it's own vacuum that is used to activate accessories.There isn't a vacuum pump on a 1500. They are only needed on diesels. The gasoline engine makes it's own vacuum that is used to activate accessories.
Assuming you mean the front axle 4WD actuator, it is on the passenger side of the front axle housing.
