    yes have vacuum at actuator.... haven,t seen movement at it... haven't looked i guess, but thinking along the lines of the four wheel drive selector switch which is located on the tranfer case where the vacuum lines go..

    There is a vacume valve on transfer case that all the vacume lines go to from engine than back up to diafram acturator, they have been known to go bad. do you have vacume at acturator? can you see acturator move when you shift it into 4 wheel drive?

1996 dodge ram 3500 5.9 diesel. wont engage 4 wheel drive. messed with vacuum line and it started bought new lines replaced them . now it don't work at all.can the control switch be

If you are getting vacuum I would check the CAD (Center axle disconnect). You may want to go to a posi-Lok cable actuator if you're going to replace the vacuum actuator, better performance and you know it's going to engage!

4 Wheel drive (Manual trans) not engaging

First, IF your vehicle has a true manual-engage for the 4-wheel drive, then you either have a linkage that needs adjusted, or there is a problem inside the transfer-case (ie- broken shift-lever, broken chain, or loose gear, depending on which metod of drive it has (they WERE gear-to-gear, in my 1981 Isuzu, which means no chain to break...)
OR- if your vehicle has the same system of activation on the 4-wheel drive, as the Chevrolets of that era (Isuzu and Chevrolet were together and may still be), it's probably a vacuum problem. See, there is a vacuum-pot that pulls the cable to actuate (lock-in) the front-axle, using vacuum from a line on the transfer-case (vacuum that comes from the engine). IF there is a hole in any of the lines &/or if the vacuum-pot itself has a hole in it, then your 4-wheel drive linkage (on the front-axle) WON'T be pulled-in, so it won't engage, at all. This happened to me in my 2000 ZR2 during a snow-storm! It clicked, but wouldn't engage.
Go online or get a reference-manual from Oreilly's, Autozone, etc. to see how your system is actually actuated.
If it is manually actuated, then look for a linkage or a line that needs adjusted (HOPE it's not inside the case!) or IF it is vacuum actuated, then you can test it by starting the engine and spraying all the lines and the vacuum-pot with WD40 or other aerosol, to see if the engine revs- which will tell you where the problem (leak) is.
Either way, GOOD luck!

1995 gmc jimmy...won't go into 4 wheel easily...took me about 45 minutes today to get it to engage, going back and forth and it seemed to engage and then "pop" out. finally engaged and stayed...

There are vacuum lines at the rear of the engine that t-off into different directions. These can become deteriorated with age and get mushy and collapse. The main culprit is underneath the battery tray. You'll have to remove the battery and the tray to get t it. The hose is connected to a vacuum actuator that controls the front axle engagement. It is always coming loose because of the sharp bend in the hose where it hooks up to the actuator. There is also a hose that runs down to the transfer case. While you're under there checking those vacuum hoses, go ahead and check the electrical connections at he front axle and the transfer case.

4 wheel drive dose not engage the button lights up but the indacator light that shows the drive train is engaged dose not light. any tips?

There several differant thing that could cause this.The system is vacuum opperated it picks up vacuum from the transfer case witch gets it from the main engine vacuum. You say you have the push bottem shift thats i switch but it lights up so thats likely OK there is another switch at the transfer case that could be the problem. But the most likely thing would be a part thats located under the battery tray called the vacuum actuator. Its a diaifram that pulls the cable that goes to the front transaxle that shifts the vehicle into 4 wheel drive. If its not working it could be a vacuum leak a linked cable or the actuator is bad or the clip that holds the cable to the actuator has poped off or even the clip that holds the other end of the cable has poped off. But i can tell you this 85 to 90 % of the time its the actuator you need to remove the battery then the battery tray unplug the hose from the actuator put a differant hose in its place this may sound slightly crud but **** on the hose if the actuator dosn't move its no good and thats the problem. Then you can disconnect the cable jack the front end of the vehicle up and try to pull on the cable you will have to rotate the wheel as you are pulling and if it engauges the system it fine. If for some reason you can't find a problem then you need to start looking at the switches or other vacuum line issues but its not likely. I hope this will get you on the right track

4 wheel drive will not engage on my 1989 gmc sierra 2500?

actually that first soultion is wrong it is correct on smaller pickups but on the full size pick ups they use a differnet sytem
there a electric actuator on front axle
there be two elctrical plugs on front axle u want the bigger of the two other one is just to turn the 4 wheel drive light on
un plug actuator then remove actuator after it removed plug it back in but leave it out of axle turn key on and shift down to 4 wheel drive the actuator should move out if it dont that your problem if i does move this isnt your problem it either the tranfer case or in front axle

My 89 chevy s-10 pickup 4 wheel drive doesnt work. the transfer case goes into gear but the front hubs seem like they dont lock in i was told it was a fuse or a vaccuum line but i have never heard of...

On the 1989 s10 it has a vacuum actuator that actually locks the front differential in ,you need to check that first, those go bad real often,and without it. There's no way it will lock in the axle, the transfer case will lock in ,but the front differential uses a actuator. It 's located under the battery tray and there is a cable towards the front of the differential. Id say the actuator cable has gone out, most parts stores can get you one ,that what goes wrong with those 99% of the time and it only takes about 5 minutes to change it out. Good luck but check the vacuum line to the actuator under the battery tray.

4 wheel drive will not engage - how do I troubleshoot

The vacuum switch on the transfercase is most likely the problem. If you remove it and the plunger is stuck in, replace it and your 4wd should engage again.

2000 GMC Jimmy Transmission Whine

Does it sound like a loud winding sound coming from the front right side? I have a 2001 Jimmy and the 4wd tries to engage when driving up steep hills and going at highway speeds. The actuator vacuum switch engaged when the transfer case vacuum switch sends the vacuumed air to the actuator. What is happening is their is either a leak in the vacuum lines, a faulty actuator switch, or a faulty transfer case vacuum switch. When the jimmy has enough air pulling in, the extra vacuum is trying to push the actuator switch in when it is not supposed to. It is a much cheaper fix than a transmission. GMC should have recalled the whole 4wd system on any of the S10's, the JImmy's, and Blazers.
