Got a 99 Durango and its being a pain in the @$$. The Abs and brake light came on yet again. I have replaced the rear speed sensor and tranny speed sensors twice now and no real change. My Genisys scanner tells me its a code 65 POWER RELAY OPEN. I clear the code and it comes back within minutes. My speed sensors are working as my speedo works and the scanner is reading correct for the rear diff sensor.

Any ideas on how to fix this or where to start. Stupid rear wheel abs is junk.

have same problem as you and changed rear diff sensor and light swent out for a day then came back on. Actually had to change sensor as speedo quit working until 20 or 30mph.

Do a search of these forums and you'll get bascially the following responses:

Rear diff sensor

ABS sensors in wheels

control module under hood drivers fender

brake light switch under stearing column (I think this is one?)
