Having problems with your 1999 Dodge Durango ?
My check engine light is on, my speedometer do not work, my ABS light and Brake light is on.
My check engine, ABS and brake lights stay on all the time and my speedo does'nt work.
Had same problem with mine. First would not show speed until reached about 25 MPH and then was intermittent. Starts with ABS and Brake Light on and no speed. Checked another website and suggested pulling sensor out of top of rear differential. About $30 part but in hard to reach area. be careful when reinstalling. Do not tighten bolt too fast as this may break the part. Allow it to slowly slide into place. Takes 30-60 minutes to replace. Works fine now.
Speed sensor located in top of rear diff is probably bad, It sends a signal to abs module for abs, it also is used by pcm and cluster for vehicle speed.Sometimes rear diff mechanical problem can damage the sensor. Trans sensors have nothing to do with speedo or abs light.
