Was working well. Took a ride on my property and decided to try 4 low. Had to kind of wrestle it back out when i wanted to put it back in 2 high. Ever since then no 4wd and no indicator light. Any ideas on what could have gone wrong?
If it’s all original probably the vacuum system on the front axle. Possibly the line leading to or the diaphragm itself.Was working well. Took a ride on my property and decided to try 4 low.

That’s another possibility. Also the vacuum switch on the transfer case may be the problem.Hmmm well I’ll have to start somewhere beyond lookin at it… I checked generally the Vacuum lines are in tacked and no leaks. I wonder if the mechanical linkage is ok ?…
Ok thank you all but boy oh boy what a dumb mistake I made that caused the problem!… when i got the jeep i noticed some really dry, cracked and missing rubber lines and rubber vacuum caps, as this was a vehicle that saw some tough times and a few back yard mechanics. So I started changing and replacing stuff, including putting a cap on what i thought was a detached vacuum line. Turned out to be the vent and check valve for the 4wd vacuum motor you guys pointed too…very rookie mistake on my part. Thanks again for the help. Removed cap and all is wellOnce the vacuum motor on the front axle connects the two halves they'll stay connected until another vacuum line moves them apart.
Shift into 4wd and check the continuity of the switch, open circuit or closed, then shift into 2wd and check it. The motor does not need to be running. Just check if the switch is making contact. Could be a burned out light too.
It doesn't take much to remove the vacuum motor to see if it's working with a vacuum.
