Why is there a beeping noise every 5 minutes or so while driving-


AS LONG AS YOUR CAR IS RUNNING FINE & HAS BEEN SERVICED RECENTLY YOU CAN ALTER THIS MESSAGE ON SCREEN TO STOP THE BEEPING, THE EASIEST WAY IS TO DISCONNECT BOTH THE + & - BATTERY LEADS & CONNECT THEM TOGETHER FOR AT LEAST 30 MINS, THIS WILL RESET THE JEEP'S MEMORY, CONNECT BACK THE LEADS & THEN WHEN YOU GET IN & START YOUR CAR THE DISPLAY BY THE GEARSHIFT WILL BE FLASHING - SET THE CLOCK BY KEEPING YOUR FINGER ON THE SET BUTTON FOR S FEW SECONDS UNTIL THE IST DIGIT BEGINS TO FLASH, THEN PRESS THE SET BUTTON UNTIL YOU REACH THE DESIRED HOUR, THEN PRESS THE SELECT BUTTON BELOW & THIS WILL MOVE YOU ON TO THE MINUTES, CONTINUE WITH THE ABOVE OPERATION UNTIL THE TIME & DATE HAVE BEEN SET, YOUR "SERVICE" SHOULD NOW BE RESET TO EITHER 7500 MILES OR 12500 MILES, I SERVICE MY 96 GRAND CHEROKEE MYSELF SO THIS IS MY "CHEAT" FOR THE SYSTEM & IT IS GUARANTEED TO WORK. BEST OF LUCK.

I have a 2002 dodge durrango, 5.7 liter, and the 4 wheel drive will not engage into 4 wheel drive, what would be the problem?


I would check the fuse panel(s) for possable fuse issue.

If fuses related to the 4 wheel drive is not pop close the panel(s) up.

I would than hope into the truck and perform the 3 quick on/off with the key(do not start truck!! and let dash units turn on before turning back off) to see if there might be a code the comes up. If so, call or look on-line for your codes to describe what the issue is or could be.

If the truck does not show codes I would move on to perform this step:
- Start the truck
- Put foot on your break
- Take truck out of "OD" Overdrive
- Place the truck into "N"
- Switch the quick switch into 4H and let it sit for a few seconds and drop you truck into "D" with the "OD" off. If the light is flashing try to drop the truck into L1 with the "OD" off and wait a few seconds to see what this does. If the light on the 4H is still flashing take the gearshifter back to "N" and wait a few more seconds. If the 4H does not stop flashing try all of these steps for 4L. (What we are doing is seeing whether or not the switch is bad or the quick switch unit that allows the 4 wheel to kick in is bad.
- If the lights keeps flashing I would go to a repair shop that you would trust to assist in this issus.

Just as a FYI, I do have a 02 Durango and the 4H switches great it is the 4L that some times takes a while to switch. Another thing to remember that if you use your 4 wheel drive to go mudding in all the time you my have burned out the unit the it takes to perform this task of engaging the 4 wheel drive all together.

I hope this helps out with your issue and remember to perform the simple steps 1st before spending big money on repairs!

Truck says to service 4 wheel drive, the fluid has been changed.


The 4 wheel drive actuator motor is not working, that is why the message, they stick if they are not used very often.
