Hi there:
That flashing is a signal from the GEM computer that indicates a failure in the Control-Trac system. Typically it is one of the Hall-effect axle speed sensors (located in the t-case) that has failed. In the auto position on your model the system monitors relative front and rear axle speeds, increasing the period of engagement of the clutch pack in the transfer case to eliminate the rear moving faster than the front. If it gets to full-lock, for example, and the rear still seems to be turning faster then it reverts the system to 4WD (locks the transfer case in 4wd as it does in 4wd-lo) and flashes the lights to tell you of the problem (in 97 and later models it reverts to 2WD in the default, auto position). Some have reported cleaning the contacts on the speed sensors has helped, but you may want to get to a dealer if the problem persists. Watch that they dont automatically try to replace the computer or the transfer case. Usually it is just a sensor problem, which is relatively easy and inexpensive to replace. There is a shift motor on the t-case on these models, but it is only used to select 4wd-lo and yours seems to do that OK.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

SOURCE: 4wd high 4wd low lights flashing

When the 4WD lights flash on and off, this indicates that there are 4WD-related trouble codes in the 4WD control module. Sometimes 4WD lights never illuminate.
The first step in diagnosing the system is to establish communication and retrieve trouble codes from the control module. After retrieving the codes, write them down, clear the codes and retest to see which codes are regenerated. False codes can be set if a component is disconnected when the key is turned on.
If the 4WD lights flash on and off, and no codes are found in the 4WD control module, try clearing the codes anyway. After a certain amount of key cycles, the codes will normally clear from the 4WD control module, but the module will not respond to commands until it is re-initialized by clearing the codes or disconnecting the battery to erase its memory.
If your scan tool will not communicate with the 4WD module, first verify that the scan tool has the proper software and the latest updates. If it does, then try another scan tool. If it still has no communication, the power and grounds that are supplied to the module will need to be tested. See if the scan tool will communicate with the other modules on the shared communication network. If they're OK, check the harness from the data link connector (DLC) for an open circuit to the 4WD module.

SOURCE: 1998 ford explorer 4wd makes a clunking noise when

The clunking noise could be coming from three different areas. Either the front or rear differentials could make that noise along with the transfer case. I would initially be looking at the transfer case as the culprit since you mentioned the 4wd light coming and going. My thinking is that the 4wd engagement solenoid is malfunctioning and trying to bring in the 4wd, then releasing it. The only good way to check the function and noise for this is to put the car on a lift.

I hve an explorer 2011 and recently has problems with advancetrac sometimes the function is correct but in other times flash "SERVICE ADVANCETRAC" and turn it off sombody had idea what i can do?


When this light flashes it means the control module for the traction control system has sensed a fault has occurred. When this light is flashing a fault can be read by a special scanner that the dealer is equipped with.

I would go to a major auto parts store that has scanners and get a free scan. Since it will either show you the specific part or a group of parts, you will know more after the scan.

What does it mean when your O/D off light is flashing and the transmissionis slipping


The flashing OD light indicates there is a problem in the transmission control system. When the Transmission Control Unit detects a malfunction it will flash the OD light and store a Diagnostic Trouble Code (DTC) in the computer. You will need to have a Ford Dealer pull the codes and determine exactly what is wrong.
I wish I could be more specific, but there are about 120 different reasons for the flashing OD light.

I have a 2004 Ford explorer and the overdrive light started flashing i have 95000 miles on the vehicle. I also noticed that it is shifting really hard and doesn't seem like it has 4th or 5th gear any...


Unfortunately, Explorers are notorious for transmission issues. The overdrive light flashing is either the detection of a shorted EPC (Electronic Pressure Controller) or a defective sensor. Bad shifts are a sign of the EPC, while good performance would suggest a bad sensor. I have also seen issues with the valve bodies and torque converters.

You can try removing the electrical connections on the transmission, cleaning them and putting di-electric grease on them, but unfortunately, you will likely have to take a trip to a transmission shop. Swing by an Autozone and have them pull your codes. If the light is flashing, a trouble code will be set to help direct you towards the issue.

OD off Light Flashing on my 1998 Ford Explorer XLT 4.0 V


The OD light is flashing to alert u to the fact that some kind of fault has occured in the transmission, the problem is in many cases a slipping condition, you need to have the trans control system tested for the trouble codes that are stored when this light flashes, this will let u know what the problem is and a direction to follow to repair it.

1998 Ford Explorer blinker problems


you need to go back over all the bulbs. Take each one out and put it back in making sure its working properly. Most likely a bulb is not grounding. I had this on a f-150 that took two days to track down. Good luck
