@Shane Klinginsmith thanks for watching and there are more videos in my playlists titled blazer

@Jimmy Hamm why don't you post a video or two of what you are doing to your 4x4 issue. I see you have a channel but no videos.

5/32" Thanks for Watching and subscribing Also there are more blazer videos in my "Blazer" playlists

Do you mean a manual transmission or transfer case?

Actuator/module on transfer case or switch in dash. If your going to keep the vehicle might want to check the condition of the transfer case also. First remove fill plug on transfer case. If fluid flows out then front seal on transfer case is letting tranny fluid slip by seal and over filling t-case If no fluid flows out of the fill hole then remove lower drain plug from t-case. Make sure catch pan is clean before draining out. Look for metal in the oil and pan. If metal is found either rebuild transfer case or replace it. Hope this helps.

@@dragsterstransmissions thanks for that help

@@dragsterstransmissions These Blazers for 4x4 drive are a pain in the ass if they are not looked after now and then Common is the vaccum hose that enters the driver fender coming off Next is the vaccum switch rusting closed or open Then the control module Then the cable that meets into the axle That triangle plastic gets Aluminum white rust build up And leaves a gap Wide enough to not let the axle engage Or even worse semi engage chewing the gears I have had 3 friends with Blazers/S10/Jimmy's all with some of theses issues that i repaired (backyard expert that bothers to look Before just replacing and hope for the best lol) Ty for the video

Same thing for my 98 blazer. 4 low won't engage. Light blinks couple times and turns off. No problem for 2Hi and 4Hi. Checked for vacuum leaks. Couldn't find any. Frustrating.

@anza westa have someone push the 4lo button while you're underneath at transfer case listening for the electric module engage. If you don't hear anything stRt at the button. Hope this helps. Thanks for watching and subscribing

@gamesarebest2462 Disconnect cable from actuator diaphragm and pull on it to get an idea how much travel is in the cable

@@dragsterstransmissions it gets pulled as far as it should but my front differential keeps disengaging then re engaging when I come to a stop

Makes a pop sound and I can feel it then it disengaged

@gamesarebest2462 manually pull cable disconnected from vacuum switch under battery and see if it will stay engaged. If not then something is wrong with front axle

@@dragsterstransmissions that’s what I figure because it pulls no vacuum so I have a wire from the cable clamped with the cable pulled and it still kicks out

@Guns Gear &Glory skid plate? Yes

@@dragsterstransmissions I was gonna ask how it bolted to the bottom, but I just figured it out. I was missing the two bolts were the back bolts to the frame crossbar

need to check your vacuum actuator and vacuum lines
