Wipers, stereo and heater doesn't work

Replace the gem module / fuse box that houses the fuse for wipers under driver side of dash. As it most likely burned up a circut path in the box enough to not let low power thru....possiable bad wiper control or partial failed wiper relay.

bad fuse ?

Check to see if wipers and heater motor work when vehicle stalls. If all the electronics that you mentioned don't work along with the wipers and heater motor, I would suspect an ignition switch failure

check rear wiper fuse and relay.if wiper motor getting power but do not work.rear wiper motor bad.if fuse and relay okay but no power going to rear wiper rear wiper switch could be bad.

located under dash at drivers right knee area

Check fuse in box,if good,then go to wiper motor,put meter to wires at wiper motor and turn on and see if you are getting power,if so,then motor is bad,if not maybe wiper switch.

It doesn,t matter what kind of vehicle it is, You have a short in the wireing some where that will have to be taken into a shop to be check out,

I suspect you have a bad wiper motor.

check the fuse for the rear wiper maybe blew when replacing it if not you have a short also check the rear wiper switch make sure working correctly

The heater motor is beneath the windscreen wiper. 1) remove the rubber edge strip that runs across the engine bay separating the the engine from the battery on one side and the brake servo on the other. 2) at the back of the engine bay the middle panel is held on by large plastic finger tightened nuts, remove these and lift out the panel. 3) loosen the rubber strip to the base of the windscreen and surrounding the windscreen wiper mechanism. 4) remove the screws that holds the plastic guttering along the base of the screen. 5) be aware of clip underneath at the inner part of the guttering where it meets the surround to the central wiper unit cowl. 6) remove the top four screws and two on the underside of the cowl and lift away. Undo the 4 bolts (10mm) that hold the wiper motor frame and remove the clip that holds it in the middle to the bulk head lower down. Disconnect the motor and lift away. 7) you now have access to the heater motor, it held by three screws. Disconnect the electrical connector and lift it out. On my own car I had a situation where the heater motor would come on or work faster as I turned left but went off or slowed right down when I turned right. Both the carbon brushes has become fixed in their passageways and the slight shift of the motor spindle in the bearings either made or broke the electrical contact between the now fixed brushes and the armature. A simple removal of the brushes to clean and lubricate has ensured no further incidence.
