SOURCE: y windsheild wipers don't move. I hear the

Possible stripped gears or the gears are not making contact.  I would replace the wiper motor.  If you can, and I am not sure, you might be able to replace just the gears.  But given how new the car is, I am sure it comes as an "all in one" unit.  It is possible to seatch www.car-part.com and see if there is a salvage yard around your area that has one cheap.

If it wont turn over try the neutral safety switch, if it wont start in neutral either the switch most likely needs to be replaced.

1999 jeep cherokee front and rear windsheild wiper turn on when you try to wash just the front


Hi Bd, If the washer reservoir motors are working and the reservoirs are not leaking and have the cleaning fluid, it's very possible and highly probable that the nozzles are blocked with dirt. Disconnect the pipes, and then put on a pair of safety goggles, Place an air hose over the outlets and open the compressed air, blowing backwards. Connect up the washer pipes and hey presto, clean screens! Regards John

How do you remove the heater motor from a merc 300d 1993


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.

Wipers and washers not working on 1967 mercedes 250sl not the fuse both just stoped working is ther a relay help COLIN


this sounds like a bad wipermotor or switch. use a test light and turn wipers on try all speeds and check for power at the motor and also check for a good ground at motor, if theres power and ground at the wipermotor then motor is bad. if theres no power or a ground at motor then its a switch or bad wire to wiper motor, start with these tests this will help you pin point the problem.

the winshield wiper water resevoir has a level indicator in the lower portion on the plastic container, and if the fluid is below the sensor turns on the light on the dash. Solution: keep the resevior filled about the sensor, and light will stay out.

Cant find heater blower motor


it should be on the passenger side under the hood on the fire wall with a plug and another wire coming out of it. But if not then it is under the dash on the passenger side next to the heater core. It should only be like four screws remember to disconnect the battery first.

Brushes on the motor may be going bad. Blower motor is in engine compartment under wiper motor assembly. The blower motor regulator is under the blower motor. There is an A/C relay behind the fuse box under the screwed down cover.
for lack of motor speed its probably the brushes on the motor or the regulator. If no cold air your charge is probably to low to engage the compressor.
