Best Answer

The shift fork in the differential could be bent or the sliding collar could be binding. When the actuator tries to push the fork, if there is any type of resistance it will cause a circuit overload and blow the fuse.

It could be a short in the wire under the driver side floor mat that's blowing the fuse.

Why is there transmission fluid in the actuator for the four wheel drive causing it to tear the rubber boot on a 95 blazer?

because your transfer case switch is letting it come through the vacuum line to your actuator needs to be replaced and lines cleaned out. but while your at it take the top plug out of the transfer case and see if a bunch of oil runs out as this can cause the vac line to fill up. if a bunch of oil comes out the seal between the trans and transfer case has gone south and needs to be replaced but if the oil level is fine in the tc change the tc switch change the actuator and clean out the vacuum lines and all should be good.

Chevy1987 blazer S10 4x4 front is not running but i shift 4x4 high and low still i can hear the gear turn and work but frontwheel dont spin.rear is fine but front not.any idea who know?

you have a actuator valve under neath your battery box. this actuator actually pulls a cable to engage the fron diferential. it runs of vaccum. now on top of your transfer case there is a 3 way vaccum switch. one vaccum lines run from your intake to the switch on the transfer case. th other vaccum line runs from the actuator under your battery box to the other vaccum prong on the switch on your transfer case. or you can just run a vaccum line from the intake to the actuator under your battery box. this is the short cut method.

Why wont your jeep axles lock?

guessing that you have one fo the central axle disconnect systems. the transfer case vacuum switch, and the vacuum actuator on the axle are both prone to failures, but easilly replaced. there are numerous aftermarket kits to convert to a manual, cable operated system, adn remove the vacuum components entirely.


Blazer will not go into 4 wheel drive?

What year is your blazer? Most common cause for it to not go into 4x4 is the vacuum actuator. The actuator is run by vacuum from the transfer case. The vacuum compresses the rubber diaphragm which pulls a cable on the front differential to lock it in. The rubber diaphragm is prone to break down and if there are holes or tears in the rubber it will only suck air and not have the amount of vacuum needed to pull the actuator cable. This actuator is commonly mounted under the battery tray. Easy to remove and inspect. 1998 blazer There is a vacuum switch on the transfer case that usually goes bad. I have replaced mine 3 times. Factory lasted until 225,000 miles and had to replace the aftermarket 2x since, one only lasted a year.


Where is the front differential actuator on a 1998 blazer?

The vacuum actuator is either in the fender or under the battery. The actually diff actuator is on the back/bottom of the front diff. Mine (2000 blazer) is under the battery. It sucks to get to. If you check the actuator and it doesn't move at all, check the vacuum, if it's not getting vacuum, check the switch on the top driver's side of the transfer case. It sends vacuum to the actuator. It has three vacuum hoses coming off of it. It costs fifteen dollars at autozone and usually greatly improves the performance of the acuator.

On a 1992 Chevrolet Silverado 4x4 It has a manual shift transfer case but has automatic hubs. The front end has an acctuator motor but it is not getting fire.what sends this fire to this actuator?

If ALL the wires are GOOD from the actuator to the transfur case, Then replace the electric switch that is screwed into the top side of the transfur case. That will fix your problem.
