Question about 1987 Mercedes-Benz Mercedes Benz 190 Class

1 Answer

Electrical nightmare Fixing a 1987 MB 190E 2.3. Every time i use the blinker switch, the left blinker causes the hazard lights and the right blinks super fast when using the right blinker. Also, either way causes the windshield wiper to engage as long as the blinker is on and the headlights at a maximum will half-heartedly blink once and go dim. My military mechanic buddy says it is most likely the ECU but cant tell without the voltometer. I need to be able to DIY bc i cant afford the european mechanics prices. A free online manual wouldnt hurt either.

You need to replace the combo switch. That switch controls turn signals, wipers and high beams. It is only held in by 2 screws and the hardest part is getting to the jack plugs to unplug the thing. Also if you have cruise control be very careful not to break the cruise stalk. The crusie switch mounts in the turn signal/combo switch. If you know how to use a phillips screwdriver you should be able to DIY Good luck.If this helped rate me. If you need anymore help get back to me.

Hazard lights not working what can we do to fix them?

It really depends on the vehicle in question but here are a few causes for your problem: 1- a blown fuse/ make sure to check the fuse for the Haz/horn and blinkers to see if they are blown. 2- a bulb could be dead or dying/ put on your blinkers, one side at a time and check the front and back to make sure they blink. If one isn't blinking or looks more dim than the others, replace that bulb. Also check your brake lights and headlights. 3- the actual hazard button/switch could be bad/ when you press it( generally speaking ) you should hear a click as it engages and closes the circuit. If there isn't any such noise, and/or there isn't any response from it, it may be the problem. Lastly, if the fuses and bulbs are good, it is more than likely electrical. Have a shop run an electrical system diagnostic to check the flasher switches, relay's, etc. Usually, diagnostics run around $100 or so dollars. I hope this helps
