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.
The vacuum switch is on the top of the transfer case. The 4wd indicator switch is on the front axle shift actuator.
The vacuum actuator is on the right side of the axle. The electrical switch is on the actuator. The vacuum switch is on the top of the transfer case.
NO it don't. The actuator is up on the front axel housing. Now the transfur case does have a switch on it that sends power to the actuator up front.
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.
It is located on the transfer case. It controls the vaccum to the actuator.
There is either a problem with the actuator in the front differential--BAD ACTUATOR. Are there is a problem with the differential ---RING and PINION asembley.
On a Dodge Ram, it runs from the intake manifold, to the switch on the transfer case, to the front axle shift actuator.
There is no vacuum switch. There is an electric actuator on the front left of the front end assembly right in front of where the cv shaft goes into the differential case and an electric actuator on the rear right of the transfer case.
The 1997 Chevrolet blazer actuator switch is located on the firewall in the engine compartment. The switch is on the passenger side of the engine compartment.
no i did not replace head light switch
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.
do you engage 4WD manually or via the button on the dash? if its the latter then your actuator switch is probably bad. tweek
