Check out your ignition switch. mine was doing the same thing. I jiggled the keys while on the run position with the key and they the heater and radio worked and all the power mirrors. I replaced the ignition switch which was very east to do and that problem was fine. I know have the ABS light and brake light on. i changed all the sensors and still on. I found that the drivers side wheel sensor has no circuit that is telling me the ABS module is bad. I found a good used one with the same part number listed on the top of it and i am in the process of replacing that.

 

ABS and Brake light still on.Replaced rear differential speed sensor and fluid and after I go 45 to 50 mph lights come on 2004 Dakota 4wd. Any help appreciated.

 

2 or 4 wheel abs?
