I haven't seen one on a '98 Jimmy, but I have a '96 Jimmy and they are probably the same. It is circular, about 3 to 3 and 1/2 inches in diameter and about 1 and 1/2 inches thick. In order to get to it, you have to remove the battery and then remove the battery tray. You will find the actuator hiding underneath the battery tray. Best of luck, Paul H.
This sounds like a YJ jeep issue, I eliminated the vacuum actuator by installing a heavy duty choke style manual cable attached to the vacuum actuator arm, that way I can lock the front diff when I wanted. Make sure you cap off the vacuum line, otherwise your engine will run poorly.
probably an actuator vacuum operated to open/close heat vents
Sounds like the actuator on the drivers side is not operating properley. To check it out, remove the panel under the steering wheel, reach up to the actuator arm and try to move it to its bottom position, if heat comes out you solved the problem.
to me it and i just went through this its most likely a problem with the front wheels actuator either its faulty or one of the vacuum lines has a break in it. Vacuum pulls the front end into gear and and if its not getting enough vacuum it will not do it. also if there is transmission fluid in the actuator or vacuum lines you may have a problem with the transfer case switch where the vacuum lines come out of the transfer case sometimes the seal goes and will put trans fluid in the lines. replace the actuator blow out the vacuum lines if trans fluid is visible in the actuator and all should be good. but if there is trans fluid in the actuator and lines also check the level of fluid in the transfer case if you take out the top bung on the transfer case and oil runs out of it and i mean more than an ounce or two if its like a litre or more then you have a seal gone between the transfer case and the transmission which will pump your transfer case full of trans oil that also needs to be replaced. if so whoever is doing it for you tell them that there is room enough for 2 seals to be put in and the seals will never give you another problem. go through these steps and all should be fine. hope this helps if this works and it should please recommend me in this forum. thanks.
The 3 control wires/ horn wires start behind the steering wheel face plate, run down the steering column and then out of the Harness to the Actuator. At the Actuator there are 6 wires. I am working on the issue myself and was able to test continuity to the 3 control wire, to all six wires at the actuator.
I have a 1998 Jimmy SLT, automatic with floor shifter. It is easier than you might think. If you look closely on the back of the shifter knob there is a retaining pin, looks like a large brad type nail, just pry it out and lift up.
It is located right on the windshield washer reservoir. It looks like a short black cylinder.

Sounds like you need to replace the drivers door lock actuator.
the four wheel drive on this unit is vacuum assisted actuator located near the battery. It looks like a diaphragm with a cable thast goes to your front end to move the pickle sliding the axles in lock. The vacuum comes from the torque converter at a vacuum swicth locate don the right side of the torque converter with 3 lines coming from it. One of tyhese lines could have a hole or rotted losing vacuum. To see this you will need to remove the skid plates. If you find a bad line tie a string to the hoses and pull them thru, when you rep;lace the line, use the string to pull them back thru. Look at the plastic plug and notice the notch on it and compare to the notch on the vacuum switch. Vacuum switch is $39.00. Check to see if the actuator cable isn't frozen up or kinked, rusted. To do this push in on the diaprahm. Thge cable should move freely. Now can someone help me? Why wont my blazer make vacuum for the same reason?
