There could be a huge problem and danger if the person soldering isn't 100% exactly sure of what he's doing as its possible to wire it up wrong, and/or give the system an unexpected surge of voltage. If possible, try to get a Wiring Schematic/Diagram and check to make sure of your work. However, replacing the wiring with an approved Mercedes-Benz part by a Qualified Mercedes-Benz technician is your best route if the car is still under warranty.

Left front turn signal was not working, and i replaced it with a new bulb but it did'nt work...please help .. ty


try changing the signal flasher. note the e-flasher looks the same. when you find a flasher turn on the e-flasher so you know you have found the signal flasher. they are usually in the same general area.

What would cause 2004 thunderbird left rear turn signal to not work and bulb is o.k.


You need to check for power to rear light if none start to check wiring in reverse. Usually at turn signal switch or under drivers side carpet.

Right front side turn signal does not work replaced all bulbs and checked fuses headlight flashers work when hazards are on front to back except driverside turn signal ,in dash right stays solid left


I don't believe it would be a bad ground for just one light. It could be a wire, a socket connector, or the bulb socket itself. See if the wire has power at the socket when signaling left, with key on. If there is power, probably a bad socket or connector. If no power, check for power coming from flasher-the wire going to front left, or driver's side. If you have power from the flasher, but nothing at the socket, the wire has probably broken.
Good luck.

Both my right & left turn signals aren't working but hazards are


If you can locate the hazrd flasher unit under the dash on the drivers side, the turn flasher unit should be right beside it and looks the same. Unplug and switch the 2 flashers and see if the turn signals work. The flasher unit is a silver and round. they are usually close to the stering colum. Let me know if that helps.

Driver side left turn signal flashing really fast. left brake light does not work. bulbs appear good. what should I do?


sometimes a bulb can be bad and appear good or there may be nothing wrong with the element but could be a problem in the contacts. if the turn signal is blinking fast and brake light out is an indicator that the bulb is bad if you do not want to replace the bulb without knowing for sure if it is bad take the one out of the other side and try it on the left and see if the problem changes to the right side. although bulbs are only about two dollars for a pack of two even though it seems good replacing it to see if it fixes it would be the first step in troubleshooting the problem. to eliminate the easiest most obvious solution first. i think a new bulb will fix your problem

Rear turn signal and hazard light don't flash (left side only)


The rear left turn signal bulb must be replaced immediatly before it melts the light socket, if it has'nt yet. Also please verify that the correct light bulb is being installed. because even though many bulbs look the same they are not identical. Installing the wrong bulb can be the begining of many, many problems in the particular circuit

LEFT TURN LIGHTS WILL NOT WORK ON 1993 TROOPER


believe it or not, a 4 way flasher can cause this even if it itself is working properly, otherwise flasher, bulbs, or switch is bad .

93 Olds 88 Turn Signals Not Working


Refer to your owners manuel to find out where the fuse box is located for the Signals. Check all fuses if all the fuses are good then and make sure the bulbs are all working. If both of these are fine you may need to ckeck the relays a small black box next to the fuses. Comes out just like a fuse but no way to see if it has gone bad you have to get a new relay and replace it with the new one.
Check each time you replace the relay to see if this is the source of the problem.
