    yes and it did not work. black wire is ground, brown is hot and pulles the actuator back in and the blue and brown together puch the plunger out on a good actuator.
    i found the problem i had a broken wire on top of the transfer case there is a switch on top.
    so i had two problems a bad actuator and a broken wire.

Bill you might want to check for a vacuum leak, i had the same problem with my truck and it wasn't the actuator was small hole in a vacuum line and as i was changing the lines, i found a little oil in one of the lines that came from the tranmission, i change the vacuum switch and that took care of the problem.

4 wheel drive on my 89 jimmy goes in 4 wheel drive


First check plug on actuator on front differential and be sure that plug is securely fastened to sensor and that plug has no rusted or corroded pins. Then test actuator and be sure it is operating properly. More than likely your four wheel drive actuator is malfunctioning.

2003 gmc envoy 4x4 problems. 4200 vortec engine. my front diff doesnt seem to be


The Selectable Four Wheel Drive (S4WD) Front Axle consist of the following components:
• Differential Carrier Housing
• Differential Case Assembly
• Inner Axle Shaft
• Intermediate Shaft Bearing Assembly (located on the right side of the oil pan)
• Electric Motor Actuator
The front axle on Selectable Four Wheel Drive (S4WD) model vehicles uses a disconnect feature mounted on the right side of the oil pan in order to engage and disengage the front axle. When the driver engages the 4WD system, the Transfer Case Control Module sends a signal to the electric motor actuator to energize and extend the plunger inside. The extended plunger moves the clutch fork and clutch fork sleeve across from the clutch fork outer gear that is splined to the right side wheel drive shaft to the clutch fork inner gear that is splined to the inner axle shaft. The locking of the two gears allows the axle to operate in the same manner as a semi-floating rear axle. A propeller shaft connects the transfer case to the front axle. The differential carrier assembly uses a conventional ring and pinion gear set to transmit the driving force of the engine to the wheels. The open differential allows the wheels to turn at different rates of speed while the axle continues to transmit the driving force. This prevents tire scuffing when going around corners and premature wear on internal axle parts. The ring and pinion set and the differential are contained within the carrier. The axle identification number is located on top of the differential carrier assembly or on a label on the bottom of the right half of differential carrier assembly. The wheel drive shafts are completely flexible assemblies consisting of inner and outer constant velocity CV joints protected by thermoplastic boots and connected by a wheel drive shaft.

4x4 does not engage in my 04 ford f150 4x4 new model. tried looking for do it yourself books but no luck


check to see if there is noise coming from either side of the front wheels. jack all four wheels and turn on four wheel drive, if one of the front wheel is not turning then the actuator on that wheel is bad. the actuator is vacuum activated so also check the vacuum hoses go to the wheels.

My transfer case fuse keeps on blowing cant find out why 1999 gmc suburban


Check the four wheel drive actuator on the front axel. It's on the front right side of the front differential housing. It's round with a big hex on it where you would put a wrench, I think it's 1-1/4". Anyway, follow the wires there's a plug about 6 inches away, unhook the wires going to the actuator. Now see if it still blows the fuse, if the fuse don't blow the actuator is the problem. It just scerws out and the new one screws in and hook up the wires. This is a fairly common problem with those trucks. On the early K series GM had the four wheel drive and the heater fan on the same circuit. The actuator would go bad and blow the fuse so now your stuck in the snow with no heat. I think GM changed that in the later years.

Four wheel drive wont engage. Tranfer case is


Sounds like you either have a vaccum leak or your 4 wheel drive actuator is not working to engage the front differential.On my 98 ram there is a black and red plastic lines that are used for the vaccum lines. They are underneath and go from the transfer case to the front axle, check to see if one or both might be cracked or broke completely.If the lines are good then it could be your actuator on the front axle. A new one is about $93 at advance auto parts and not very hard to replace

01 Chevy Silverado 4 X 4 not working. 4WD light


Having the same exact problem but with my 1999 escalade. Thought it was the actuator bought a new one installed it transfer case would engage but front end wouldnt lock. Took it out of housing left it plugged in got a friend to go through all the 4wd for me and the plunger never moved out the actuator. Checked my wiring harness which is a four prong ann it had one hot prong like it is suppose to. Traced wires even replaced dash switch same problem. Taking it to local dealership tom to have it checked for codes. I was told it could be the transfercase actuator even though its workin that actuator is what sends power to the front to engage the actuator to lock the differential.

Front axle stuck engaged


w9fro..In1995, and other model years, the actuator used to engage the transfer case into four wheel drive is oil filled with a heating element.
When you select four wheel drive the element heats up, the oil expands and engages the transfer case. Unfortunately if the actuator fails, the truck remains in four wheel drive. GM has an improved actuator so the problem does not repeat.
As always, check the basics, power, grounds and switch at floor select before replacing the actuator.
Also, if the truck is truly stuck in four wheel drive, you can tell by turning the truck in a tight circle. If the front end wants to "bunny hop" it is definitely engaged.
Best of luck, let me know.
Regards,
