4wd lights flashing

This problem sucks, well i have 98 ranger with same problem but i think i may know what is wrong but as for us, we will just have to work this out I'm here to help.

I figured out that if you put it in 4x4 it engages all nice and everything but when i go to remove it from 4x4 it will sit their and click and if you let it sit and click about 3 to 4 maybe 5 times that is when the problem occurs and no 4x4 action at all and flashing lights but so far if you engage 4x4 with all noise down listen for clicking behind dash and just dont let it sit and click just try it and if it clicks more that 3 times put it back in 4 and try disengaging again till it dis engages before it clicks 3 to 4 times or so but i did try to replace it and it worked fine for day or too and then i had the same problem.

So I replaced the transfer case actuator and the problem is fixed. Here are the wiring diagrams and the encoder location #36 which I used to help me figure it out.

I hope this helps people, Cheers!

four wheel drive electric switch not working properly.doesnt engage in four wheel high ,but it does in four wheel low.light says that it is in four wheel low but it wont disengage now HELP!

the motor on the transfer case may be failing.

did you check or change the oil in the transfer case??

if i lock the hubs in the light stays on but will not go into 4x4

TESTING

ELECTRONIC SHIFT TRANSFER CASE

Circuit Protection

The battery feed circuit, through a circuit breaker, provides memory capability for electronic control module. Ignition RUN and ACC circuits, through a fuse, supply power for switches and electric shift
motor. The circuits supply power for illumination of instrument panel switches.
Control Module Self-Test

1.
To perform electronic control module self-test, remove 5-wire connector and 8-wire connector from module. Turn ignition switch to RUN position.
Activate self-test switch and note result. If LED flashes 4 times control module is okay. No illumination indicates a dead module and module must be replaced. A steady indicator light
indicates control module is inoperative and must be replaced. See Fig. 3 .

Speed Sensor

Ensure speed sensor resistance is 225-275 ohms at module connection with vehicle stopped.
8-Wire Pigtail Connector Test

1.
With ignition off, unplug the 8-wire connector from module. Connect voltmeter between terminal No. 8 and ground. Battery voltage should be present. See Fig. 4 .
Connect voltmeter between terminal No. 7 and ground. Turn ignition to RUN position. Battery voltage should be present.
2.
CAUTION: Disconnect battery cable before proceeding with ohmmeter
tests. Never connect an ohmmeter to powered circuit.
3.
Connect ohmmeter between terminal No. 6 and ground. Resistance should be less than 10 ohms. Connect ohmmeter between terminals No. 4 and 5 of connector. Resistance should be less than 10
ohms.
Connect ohmmeter between terminal No. 3 and ground. Resistance should be zero ohms. Resistance between terminal No. 2 and ground should be zero ohms.

5-Wire Harness Connector Test

1.
Connect ohmmeter between terminals No. 1 and 2. Depress and hold 4WD switch; resistance should be less than 50 ohms. See Fig. 5 .
Connect ohmmeter between terminals No. 1 and 3. Depress LOW RANGE switch. Resistance should be less than 50 ohms with switch depressed.
Connect jumper wire between terminal No. 4 and ground. Turn ignition switch to RUN position. Light in instrument panel and low range bar should illuminate. Turn ignition off and remove
jumper wire.
Connect jumper wire between terminal No. 5 and ground. Turn ignition to RUN position. The light in the instrument panel and 4WD bar should illuminate.

8-Wire Harness Connector Test

1.
Turn ignition off. Connect ohmmeter between terminal No. 1 and ground. On manual transmission, depress clutch pedal and observe ohmmeter. Resistance should be less than 50
ohms.
On automatic transmission, shift transmission into Neutral and observe ohmmeter. Resistance should be less than 50 ohms.
To check speed sensor continuity, measure resistance between terminals No. 2 and 3. See Fig. 6
There should be 200-350 ohms. Connect ohmmeter between terminal No. 8 and, in turn, terminals No. 4, 5, 6 and 9. Resistance should be as specified.

Electronic Transfer Case Feed

For functions of transfer case feed terminals, See Fig. 7 . Ensure battery voltage is always present at terminals No. 1 and 4. Test remaining terminals for continuity to locations listed in function chart. See
WIRING DIAGRAMS .

Got a problem with a 1995 Ranger XL 3.2. The 4x4 and the 4x4 low lights flash 6 times then stop for a bit then flash again 6 times in a loop. When it flashes and I try to put it into 4wheel drive there is no response. I took it in to a Ford dealership along time ago for the same issue and they said it was because the 4x4 hubs went out and I needed to replace the hubs, so I had them install warn manual locking hubs. Any ideas??

I want to wish you luck on this! All I can say is spend the time to do lots of testing before replacing parts!

I had a similiar problem on my '99 Suburban (luckily under warranty). The dealership ended up replacing about 5 actuators + the transmission computer & 4WD computer before realizing that it was just a cracked wire inside the main wiring harness that was shorting out.

In short, just make sure to do your homework no matter what answers you get, the time spent is much better than spending $1000's when you just need a $0.99 roll of electrical tape!

Now hopefully somebody will come in and let you know the testing procedures, that I have no clue about!

The 4x4 low and high ligths flashes intemittently whilst the eletronic switch is on 2wheel drive.
How do I fix it and what is the problem?

If the light is flashing, you need to have the computer scanned when it does it. Chances are there is a short in the wiring at the transfer case actuator. However, the scan should direct you.

Let me know what you find.
