Question about 1987 Mercedes-Benz 300-Class

1 Answer

Windshield wiper of 1987 300E

This feels silly. I raised the windshield wiper blade to clean the windshield and it is caught in the up position away from the windshield. There likely is an easy way to release it- does anyone know this solution? Thanks. Mark

Hello, Spray some wd-40 etc at the joint that the wiper blade pivots on and then work it back and forth. Sometimes you really have to push harder than you thought it could stand.
I hope this helps.
CYA, Gator241

Wipers dont work


This is a complex wiper system . Here are all the components involved !
The Wiper/Washer System consists of the following components:
?€¢
Windshield wiper/washer switch


?€¢
Body control module (BCM)


?€¢
Wiper 1 relay


?€¢
Wiper 2 relay


?€¢
Wiper diode


?€¢
Windshield wiper motor


?€¢
Windshield washer pump


?€¢
Windshield washer nozzles


?€¢
Windshield washer solvent container


?€¢
Windshield wiper arm and blade assemblies


?€¢
Windshield wiper transmission


?€¢
WIPER/SW 10A fuse


?€¢
WIPER 25A fuse


Circuit/System Description
The body control module (BCM) controls the wiper motor based on input from the windshield wiper washer switch. The BCM monitors the wiper washer switch through three separate signal circuits and a ground circuit. The windshield wiper switch high signal circuit is used to determine high speed wiper operation, the windshield wiper switch low signal is used to determine low speed, intermittent, and mist operation through the use of a resistor ladder, and windshield washer switch signal circuit is used to determine washer operation. The windshield wiper motor park operation is controlled by the BCM. The BCM recieves an input from the park switch to determine wiper blade position. When the wiper blades are at the bottom of the windshield glass in park position the wiper park switch will open and the circuit will be pulled up to B+ by the BCM. The park signal will be pulled to ground by the wiper motor park switch while the wiper blades are not in the park position.
The BCM controls the windshield wiper motor through two output controls, controlling two relays which determine the desired wiper speed, high or low
Diagnostic Trouble Codes (DTCs)
The body control module (BCM) monitors the voltage on the windshield wiper switch signal 2 circuit for diagnostic purposes. If the circuit is shorted to voltage while the driver is commanded OFF, the BCM will store DTC B3715. If the circuit is shorted to ground while the driver is commanded ON, the BCM will store DTC B3715. Refer to DTC B3715.
It would be best to have a factory scan tool to diagnose this problem . it would make it easier anyway .

slide the new wiper assembly on.

tighten the retaining nut and lower the arm back down to the windshield. you will need a wrench and

How do I replace wiper blades


First, pull on the wiper arm until it raises and locks into the service position. The wiper arm will stand by itself once you raise it past a certain point.
Then find the clip on the underside of the wiper arm (rotate the blade slightly to get to it.
Press the clip in while simultaneously pulling the old wiper blade off the wiper arm. You can then discard the old blade.
Align the new wiper blade with the wiper arm track. Slide it along the track until you hear it click.
Repeat this process with the other wiper blade to complete the replacement of wiper blades on your Highlander.
Return the wiper arms to their normal position against the windshield. Done!

The wiper motor on my 1983 Ford Ranger still works but the wipers no longer move. I think there is a failure of the mechanical linkage. Where do I go to find repair parts?


why do you think the motor still works if the wipers don't move? Can you hear the motor run or can you see a little movement when you turn the switch on?

What happens when you activate the washers?

go to a salvage yard that allows you to remove the parts yourself. Then you can see how the motor and linkage assembly comes out.


don't have 1983 info, but here is 1994:

I cant figure out how to change my windshield wiper blades on 2001 ford ranger


How to Replace Wiper Blades Guide (Typical):
Potential tools needed to replace wiper blades:
  • Flat blade screwdriver (small)
  • Small nosed pliers
  • Latex or vinyl gloves
  • Safety goggles
To replace wiper blades theactual action of replacing the blade is no big deal, it's the locationof the blade down below the hood that can make it difficult though.Sometimes it helps to open the hood to gain access to the wiper blades.Other times it is helpful if the wiper blade is somewhere in the motionline of wiper action. The trick is to get the wiper to stop somewherein the wiper arc. Turn the wipers to the on position and allow thewipers to start, and then shut the key off when the wiper has arrivedin a desirable position on the windshield. To replace your wiper bladesplease follow the step by step instruction below. Also, watch the How to replace wiper blades video below to gain additional information. The method in which the wiper blades are attached will vary slightly.
  • Step 1: With the hood closed, turn the wiperson, when the wipers are in the middle of their arc turn the key to theoff position. (Note: if this can't be done because of wiper conditionand you want to avoid scratching the windshield please open your hoodto gain access)
  • Step 2: Locate the mounting clips at the top pivot on the wiper blade
  • Step 3: Release the clip and remove the wiper arm
  • Step 4: Match the size of the old blade against the new blade to ensure proper fit and operation
  • Step 5: Reinstall the new wiper blade and recheck wiper operation

Common Problems:
  • Make sure the wiper blades are the same size as the original blades.
  • When replacing wiper blades not getting the blade onthe mounting pin completely allowing the wiper arm to become dislodgedand possibly causing damage to the windshield.
  • Using wiper blades after the blade has failed permanently damaging the windshield by craving scratches in the wiper arc.
  • Wiper blade can create a chattering noise when theblade is not properly balanced allowing the blade to "flop" back andforth as the wiper direction changes.

I hope help you with this (remember rated this help) Good luck.
