    I have the same problem, I changed that vacuum switch, didn't help! If I connect the hoses to the front axle by my self it goes in perfectli! Is there some adjustment work to do on the linkage there or does someone have a good idea what else could be wrong?

It sounds like you may have vacuum problem. There are several places you need to check. FIrst check the vacuum line from the engine to the tranfer case. Then check the vacuum lines from the transfer case to the front differntial. If all lines check good, there is a vacuum swith on the top of the transfer case that may be the cuase of your problem.

Dash Vents


Check in the engine compartment for a broken vacume line or a line that has come off. If not under hood check for the line off under dash usually under passenger side.When you fix the vacume line vents will work again if this was helpful please leave good feed back

Pistol09pete,

It sounds like you have a problem with the vacuum lines that travel from the transfer case (these should be color coded lines that are green, red, and black). Goodluck

1995 dodge 3500 4wd wont engage have shifter on floor light wont come on or 4wd wont engage


Any time your dealing with a 4x4 system the best start is at you front axle. Its primarily a vacuum leak so check to see if the 2 vac lines are hooked up (its good to check the electric connections.). When your 4 wheel drive is engaged and the motors running you should have vacuum at one or both of thee lines depending on if your in 4 hi or low .
If no vacuum at axle check the Vacum switchs(the plug with 4 vac lines) on top of the transfer case it will have 2 feed lines(grey & green) they conect in to the into the vacum harness on back of motor (passanger side). A vacum schematic is normally located on the raditor core support (right under the hood next to hood release)
Hope this helps

Clicking noise from font driver side wheel 4 wheel drive


There is a vacum powered actuator on the front differential housing on the passenger side. It pushes one way for 2WD and the other way for 4WD. If it gets an erratic vacum signal it can cause the clicking as it goes between 2WD and 4WD. It gets it's vacum from two valves mounted on the firewall just behind the battery(to left). The white line feeds manifold vacum to the valves. Check for vacum at white line with engine running. If no vacum there is a break in line from manifold (not likely in this case). If vacum check the pink and blue lines by applying vacum to each one. The vacum should hold. If not check lines from valves to vacum actuator. If both lines hold vacum check valves. Remove electrical connectors from both valves. Connect a wire from one of the terminals of the valve to ground. Touch a wire from the battery + to the other terminal of the valve. Listen for a clicking sound. If no sound valve is bad. Replace valves(s). Also have someone watch position of actuator shaft as you move the selector between 2WD and 4WD. There should be movement. If there is an intermittent problem sometimes it will and other times it won't.

Push button 4wd wont engage in 4wd


there is a small sensor on the top of the transfer case that has three vacume lines into it. that little switch has a bearing that the vacume sucks up to operate the 4 wheel drive. replace as well as check the vacume lines to make sure you dont have a hole or leak in them
