Hello everybody !
My Explorer 1997 XLT Control Trac, during hot summer days here in Brazil, the speedometer oscillates, indicating speeds lower than the actual speed.
Sometimes the 4WD Lights flashes 5-6 times in 2 minutes intervals. It occurs with and without the Cruise Control engaged, when engaged the throttle pedal also oscilates. I replaced the Rear Differential Speed Sensor, but the problem remains. Does this vehicle have another Speed Sensor, in the transfer case ?
The ABS light NEVER was ON.
 






I forgot to say, most of the times the speed oscilattes down to zero, and the spedometer does not work until the next day.
