wipers stopped -----It could only be either a fuse, the switch/or wiring, or the motor burned up.
============ Power windows stopped
There are three locations for the fuses:
1. Under the hood on the right hand side in the rectangular black plastic box that is about as large as a normal first aid kit.
2. Under the back seat. Pull up on the front of the seat to unsnap it. then pull towards the front of the car. Reverse to install. The box is in the middle towards the front.
=================
Check the buzzer relay and the window control module. The buzzer relay is located above the fuse box and the control module is located under the rear back seat. You may need to replace them. The power window control module can be quite expensive
3. Under the right hand (passenger) dash board. Remove the kick panel with 2-3 screws. Its right up against the right hand wall. This is the location for your fuses for the windows I think.
==========
4x4 stopped working.
 trasfer case may be broken

Hi and welcome to FixYa,

Initially, to my understanding, it would be very rare for all your described components/parts of the Mazda B4000 to go out simultaneously. The only probable reason would be a common bus line to all which would not be logical unless, there is a central/common controller for all. In some vehicles, there is a Body Control Module. This is similar to the engine management computer in the sense that the BCM controls all the features/functions of components/parts inside the vehicle in a similar functions as the ECM does in the engine bay. Might this be a possibility?

Pls try and reference by clicking here and here.

Good luck and Thank you for using FixYa. Happy Holidays.

This sounds like a lose connection inside of door frame ..take apart door on drivers side and look for loose or broken wire or connection!

All of these accessories run through and are controlled by the GEM,(Generic Electronic module), I worked for a new car dealer on trucks like your model many times and this was the issue when these things all stopped working at the same time.

Where is the wiper relay


A wiring diagram doesn't show a relay, just a 25 amp fuse in fuse panel under driver's side of dash. Intermittent working is usually from a loose or poor or corroded connection, or the switch is old and tired, or the motor is old and tired.
Here is one way to check, if you have a test light: when the wipers are not working with wiper switch on high, and key is on, pull off the connector to the wiper/washer motor module (in the engine bay, on the firewall) and check if the purple wire has power. If it does, you probably need to replace the module. Inside the module is a park relay switch (to return wipers to down position when turned off) and a circuit breaker between the motor and ground.
If the purple wire does not have power when key is on and wipers on high, the connection is lost between the switch and the module, or the switch may be malfunctioning. The switch has 5 wires, white wire from 25 amp fuse (power in to switch), a pink wire (for the washer motor), a purple wire (high speed wipers), a dark green wire (low speed wipers), and a gray wire (for the park relay switch inside the wiper/washer motor module). If you see a yellow wire also at the module, that is part of the low speed wiper circuit (the dark green wire) coming from the park relay switch and then to the motor.
Good luck. Post back if further questions, or need more help.

The fuses are good put in new wiper motor but wipers still wont work


check for power both sides of fues and then at switch,most switches in steering colum have relays some switches make contact with earth so no power goes to then they just make the earth circet for the relay ie relay has power all the time when it is earthed the switch in the relay turn on and power to the wiper motor,but first check for power and earth at the wiper motor if you haven't already,that should have been before replacing motor

I have a 93 jeep cherokee that for some reason the wiper motor will not work can you help


Check if there is power going to the wiper motor when wiper switch is turned on,you can use a multimeter or test light,if not check fuses,wiper switch and wiring.
If there is power at the wiper motor,most likely you need a replacement unit.

I have a1992 ford explorer the front and rear wipers quit workin


check for power at the wiper motor. If power at the wiper motor but no wiper action then replace the motor. if no power at the motor then use a jumper wire and put power to the motor. Does motor run? if so check for open circuit in the wire someplace.
