Whenever I try to activate the left or right turn signal on my 2000 slk230, the light just comes on solid and does not blink. WHat can be done to fix this?

Thanks

thats mean there is a short somewhere , have you check to see if there are any burnt bulb(s)

maninblack is half-right. It probably means there is an open somewhere (not a short). I had this problem on my '02 SLK32 and it turned out to be a loose connector on the signal lamp right next to the passenger side headlamp. I pulled it off, cleaned it up a bit, put a little oxidation inhibitor on it, and put it back on. I did the same to all of the other lamp connectors I could reach. That fixed it and I haven't had a problem since.

FYI, the oxidation inhibitor isn't required, but it might help keep problems from recurring. It just a grease that keeps the conductors from oxidizing and also helps prevent electrical arcing. You can buy little tubes of it in the electrical department of any hardware store.

Mine is doing this too. All the lights are fine and it also goes on solid when you operate the hazard flashers.

I have traced this prob to the Combination Module, inside this box is a few relays and I found by giving the module a whack with the screwdriver handle it would work fine for a wee while. Once I could see which relay was the one in that circuit, I gently cleaned the contacts and its been fine for a few days.

Take care with this module as it also controls the roof and interior light delay and probably much more. To replace the module costs arount 2,700 NZ Dollars so Im not ready to do that yet.

I talked to a MB mechanic today about this problem and he said he would bet it's a bad hazard switch (the actual red triangular switch in the dash), as it's a common fault in MBs and he replaces 100s of them each year.

I’m having a similar issue. But when I turn in my lights the left signal light comes on and stays on doesn’t blink when activated just stays solid

I looked on a other site and they gave me a fix this was to use a thin bit of sand paper and file the points in the relay did that now works fine including the flash with central locking and hazard lights
