Windscreen wiper on Mercedes C200 not working. Replaced it 4 years ago. Slowed down in cold weather - 2; then stopped.

Windscreen wipers not working after jump starting vehicle.

Affected vehicles

• All models.

Problem

• Windscreen wipers not working after jump starting vehicle.

Cause

• Windscreen wiper motor and engine wiring harness damage caused by jump starting vehicle using incorrect earth point.

Remedy

Parts Earth point warning label

• Carry out electrical, mechanical and component tests (as applicable) to eliminate any other possible cause(s).
• If no fault(s) found: Replace windscreen wiper motor and engine wiring harness.
• Attach earth point warning label Fig.126139.1.

First time you must diagnose why windscreen wipers going slow and scratching windscreen.
In order to find out the cause of wipers stopping you can try follows:
1. Carefully extract the wiper arms from their axles (two pieces). In some cases you need to use an extracting tool. Heed of the windscreen !!!
2. Disassemble the plastic covers from the bottom of the windscreen.
3. With the bonnet up you can start the engine, (transmission in "N" or "P" position and parking brake on). Now you must switch on the control lever of the wipers, and go to the engine compartment. If the wiper motor runs let the wiper motor running for a few minutes and switch off. Go to the step 4. If the wiper motor do not runs you must check first the electrical feeding of the motor. It is necessary to unscrew three bolts of the mechanism and disconnect the electrical coupling (difficult assurance). If the electrical feeding is OK you must replace the motor - steps 5, 6, 7. If not you must check electrical connections, the control switch of wipers and electric cables.
4. Now you must check the two bearings of wiper mechanism with your hand. In the most cases the left bearing is out of order (is very hot). This is the most encounter fault of the wipers running at Audi.
5. For have enough space to manipulation the wiper motor together with their mechanism you must extract the plastic cover of the engine computer box, and extract also the box screws. Then you can move slowly the engine computer box, just for a few milimeters.
6. You must disconnect the electrical coupling of the motor (difficult assurance), unscrew three bolts of the mechanism and extract together with the motor. You must move them slowly between windscreen and engine computer box until the wiper motor go out together with the mechanism. This is the most difficult operation!
7. Now you can repair the bearings, replace entire wiper mechanism or replace the wiper motor. It is not very simply, but it works.
Heed of the windscreen !!!
Refit all in reverse order.

Well if I could read and write I would do a google search, on the other hand there are folks who can only read and write so far as to ask others to do it for them. If you put a used wiper motor in it you will be doing it again next year. Never replace a wear item with a used wear item. The car wasn't cheap, get used to it.

have you used the owners manual to try and replace the fuse for the windscreen wipers ? (manual for the instructions and location of the fuse box)

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.

Firstly check the fuses, if they are ok and you can here noise it will most likely be the linkage has popped apart, if no noise when on then check the switch.

*If you had cold weather when this happened, it is common for the motor to strain and blow the fuse*
