It is located on the transfer case. It controls the vaccum to the actuator.
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.
There is a switch on the transfur case that sends power to the front differential 4x4 Actuator when you shift the 4x4 lever,need to check the switch with a test light to see if it has power going to it. If not then check fuse in fuse box for the 4x4, If it does have power going to it, then go to the front housing and check the Actuator with a test light to see if it has power going to it, if no power then problem is in the wireing from there back to the transfur case switch. If you do have power at the front, then replace the 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.
It helps if you are a contortionist to do this job. First you need to remove the retaining clip that holds the brake master cylinder actuator rod to the brake peddle lever. Then slide the actuator rod off the brake peddle lever, the brake light switch will come out with it. Disconnect the electrical plug from the switch and remove switch. Reverse order to install. Most of this procedure is done using one hand, good luck.
what is an ignition actuator i work on Chevrolet and have never heard of it are you talking about the switch
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.
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 95 ranger, the 4wd actuator needed replacing. on a 95 ranger, the 4wd actuator needed replacing. However, you can put it in 4wd and tap the from housing and it will sometime go into gear. The lack of use causes the actuator to freeze-up.
There is a temp blend door controlled by the temp control switch. The temp blend door is run by an actuator. If this actuator needs replacement it requires removal of the dash assembly (big job).
The vacuum switch is on the top of the transfer case. The 4wd indicator switch is on the front axle shift actuator.
Need to check the 4x4 Actuator on the front housing to see if its working And there is a electric switch on the top of the transfur case that sends power to the front actuator that ingages ring and pinion. Be sure to check fuse with a test light ( Fuse Box )
