Where is the signal turn light flasher module located in the 260E (1987).
I think my car need a new flahser module. When I make a right turn and put the right turn signal light on, it flashes really really fast. I looked in the fuse box but don't see anything but fuses, so it must be located elsewhere. Can someone tell me? Thx

I'm having the EXACT same problem with my w123. Have you checked out the wiring to this light (esp. the ground)? This weekend, I plan on running a new ground to find out if that is my problem. Have you viewed the activity @ night with your headlights on? I think mine may be grounding out on the constant.

Uh no... How do I check out the wiring to this light? The electrical problem in this car is kinda weird right now. I don't know how to handle it. Seems problems come and go.

Check the wiring schematics. If you know what color ground your car typacally uses (most on mine are brown colored), I plan on gator-clipping to that post on the light socket, and attaching it to a known ground. If that cures it, it's the ground. The thing that I'm having trouble with is the fact that if the system isn't right, it will quik-flash as if there is no bulb. That's where my fun is.

I wish I am in such a lucky position as you. I bought this car recently and have no schematic , in fact it didn't even have the users manual. But I am in the process of obtaining one.
