Turn Signal / Flasher Problem

[lunarx]

My 451 developed a fast click on left turn signal.
I noticed both the Left Front and Left Side turn signals were dead.
Bulbs were good.

It turns out there is a relay for the Front & Side turn signals.
Relays are located towards rear of the fuse box, under the dash.
Left Front/Side Relay was bad.

I just figured the next person with this problem might find this info helpful.

Now I have to try to buy a relay from a local auto parts store.

Yes, I could just go back to dealer under warranty, but it's way too much hassle to drop my car off, and leave it there for a day or two, for such a simple fix.

Why would you need to leave your car at the dealer for days to replace a relay?

Couldn't you just drop by the dealer and pick one up?

BTW: Thanks for the great info

Turn Signals work again

$9.99 got me a relay from Kragen.
Niehoff RL35451

Not an exact equivalent (no coil resistor), but it works perfectly.

It's hard to believe the dealer wants $50 for the original:
Tyco/Hella A 002 542 13 19 (26)
(This relay also serves duty as a Fuel Pump relay in some Mercedes.)

The equivalent Bosch Relay is 0 332 019 103
This also has a resistor, across the coil, like the dealer relay.
It's 50A rated and only $6.99.

Tyco relays, Bosch, power relay,75 amp,high capacity,Automotive,truck,equipment,

http://http://bowery.com/maserati/home/files/bosch%20relays.pdf
(pg 8 & 9)

I'll pick up 2 of these and change both out.
It's hard to pass on such a good deal.

So if one of you ever needs a Turn Signal Relay, and can't find one, I'll have some spares I can send your way.

Does anyone know if these relays will work on a Smart ForTwo 450?

I am having a problem with the passenger-front turn signal. It doesn't blink for hazards but does come on for the parking and headlights.

I believe turn signals in the 450 are controlled by relays inside a sealed "SAM" unit. As such they are not independently replaceable; the entire SAM must be swapped out.

Most usual suspect for your symptoms is a dodgy light bulb or loose connection.

Sunny,

Thanks for the tip! I thought it might be a dodgy light bulb so I replaced it. For two right turns it worked fine but then stopped blinking after that. I imagine the bulb may have come loose or that the contacts need a cleaning.

Lunarx,

Thanks for posting this info along with the vendor part number and links. Mine developed the identical problem. Ordered 2 relays to resolve.
