I put a new belt on it and it doesn't seem right still it seems as if the belt is slipping. But other times it goes fine but the high and low range isn't working right
SOURCE: low range 4x4
4x4 low function will only engage when vehicle is stopped in neutral with foot on brake. try that
SOURCE: replacing the wiper control unit on a 1999 honda accord
yes it will get worse-yes they can stop working all together-you must replace the arm on which the switch is attached connected to steering column- get a used one from junk yard and a book at library
SOURCE: No high beams on 1999 Dodge Caravan; low beams work fine
replace the switch in the column i had the same problem on a 1996 caravan when i replaced the switch the problem stopped
SOURCE: 1999 ford expedition - transmission slip?
the flashing O/D light usually means you have a bad speed sensor that sends speed info to the engine & trans computer.
Vehicle Speed Sensor
The vehicle speed sensor (VSS) (Figure 42) is a variable reluctance or Hall-effect sensor that generates a waveform with a frequency that is proportional to the speed of the vehicle. If the vehicle is moving at a relatively low velocity, the sensor produces a signal with a low frequency. As the vehicle velocity increases, the sensor generates a signal with a higher frequency. The PCM uses the frequency signal generated by the VSS (and other inputs) to control such parameters as fuel injection, ignition control, transmission/transaxle shift scheduling and torque converter clutch scheduling.

Some trans use an OSS, Output Shaft Sensor instead of a VSS. Depends on which trans you have, 4R100 or 4R70W
Transmission Control Switch (TCS) and Transmission Control Indicator Lamp (TCIL)
The transmission control switch (TCS) is a momentary contact switch. When the switch is pressed, a signal is sent to the powertrain control module (PCM) to allow automatic shifts from first through fourth gears or first through third gears only. The PCM energizes the transmission control indicator lamp (TCIL) when the switch is off.
The TCIL indicates overdrive cancel mode activated (lamp on) and electronic pressure control (EPC) circuit shorted (lamp flashing) or monitored sensor failure.
Output Shaft Speed (OSS) Sensor
The output shaft speed (OSS) sensor is a magnetic pickup, located at the output shaft ring gear, that sends a signal to the powertrain control module (PCM) to indicate transmission output shaft speed. The OSS is used for torque converter clutch control, shift scheduling and to determine electronic pressure control.

is your fluid the right grade check shift linkage loose or worn or binding manual shift or bad shift fork or moter on automatic shift
