    The actuator moves when unpluged, when it is put back in it blows fuse. Could there be another switch or anything else I should check

  • J288 Feb 14, 2012

    When actuator is removed it does not blow fuse and it works fine. As soon as I put actuator back in and push 4x4 button and put it in drive the fuse blows. Lights on buttons just flash

SOURCE: 1998 GMC Sierra Signal Fuse Blowing

it seems you have a short in either one of the lights or interlock. all are connected to the same fuse. trace the wiring from the fuse box back to the component. Using a test light test in between the wires. check for any obvious breaks in the wiring.

Take the front axle actuator out of the axle. Plug it back in and have some one push the 4x4 button. The actuator should move, it's a liniar motor. If it doesn't then the actuator is bad or there is a wiring problem. If it does there is a problem in your front diff or some where else in the system.
I'd take a guess and say it's the front actuator.

2000 chevrolet blazer 4x4 fuse keeps blowing


Don't know the vehicle specifically, but if you've replaced all the components that are run from this fuse then the only thing left is the wiring loom itself. Maybe some foreign object (rock or stick) has damaged the wiring and the wire in question is shorting to earth somewhere in the loom. To check this all you need to do is work backwards from the furthest point. That is disconnect the actuator on the transfer case and turn the switch on. Then disconnect the sensors and turn the switch on, disconnect the actuator on the front diff and turn the switch on. If after everything is disconnected the fuse still blows, then it MUST be the wiring loom. Have you done any " home handyman" wiring under the dash? maybe you nicked a wire by accident? It's a fiddly process, but give it time and you'll get there.

I have a 93 gmc sierra 1500 4x4 every time i engage it into 4x4 it blows the 4x4 fuse


Try unplugging the front axle actuator (at the front differential). If the fuse stops blowing, you have a short inside the actuator.

My 4x4 fuse keeps blowing. I put in a new one, shift into 4 wheel drive and it blows. Is it a short or could my 4 wheel drive be out. It is a 1994 chevy suburan.


Try this,on the front axle there is an actuator for the 4x4,unplug it and try to engage 4x4 with it unplugged,if the fuse doesn't blow,actuator is bad.
Also look at the wires going to the actuator they get damaged from brush and things.

I have a 93 chevy z71. I can't get the auto locking hubs to lock. My transfer chase works. But when i try to shift it into 4hi or 4low the 4x4 fuse in the fuse box will blow


The actuator down on the front axle is probably stuck, or shorted internally. You can prove this by unplugging the actuator (it's down by the diff. on the front axle) then try a new fuse and see if it still blows, there is a short in the wiring, if not it is the actuator causing the short.

Your vehicle is an old OBD1 Vehicle.
Forget fuses and sensors,they have no role

Check for vacuum to the front axle vacuum actuator,when in 4 wheel
The console shift indicator bulb, is probably burnt out

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.

Electronic 4x4 will not disengage


Sounds like the shift motor on the transfer case is bad. You replaced the actuator on the front differential right?
