this one in fairly simple, on most of the newer cars the speedo is driven off the abs sensor so all you need to do is get new abs sensor/s and that sould fix your problems It is located on the rear differential, facing the front of the truck
Possible abs sensor failure.
I would guess that both of your brake light bulbs are burned out, and only the high mount bulbs are still working.
There could be several things wrong with your Durango including bad speed sensors, a bad instrument cluster, broken cable or connector, etc. There is a very common problem with Dodge Durango's, however, that causes the speedometer to fail or only begin to work after about 15-20 mph. On my 1999 Durango, the anti-lock brake light was permanently on along with the parking brake light. My speedometer did not work below about 15 mph. I did a serach online and found that lots of people had this same problem and it was due to a faulty rear speed sensor. This sensor is mounted on top of the rear differental and can easily be removed and replaced with a socket wrench. A new one costs about $12. If you are experiencing similar problems I would suggest trying to replace it.
Is your speedometer not working? If your abs light or tracs light is on it may be the brake control module causing your speedo not to work.
To replace the brake light on a 2001 Dodge Durango the light lens must be removed. It is held on by a clip on one side and a hinge on another. It opens like a door to access the brake light housing.
under the dash
It's at the top of the brake pedal under the dash.
The 2000 Dodge Durango brake lamp is a 3057 bulb. See sources and related links for a picture and additional information.
I know on my durango...I went away for a week and when I came back my abs and brake light came on and stayed on. It ended up being one of the sensors on the brake went bad. I hope maybe this will be useful.
because your car is broken
Check the fuses and if they are good then check the brake light switch.
If the speedometer and abs light are not working then you have a speed sensor problem. If the speedometer or odometer are not working then you will need to take it to the dealership and have them send it off for repair.
