Normal Mod 451 Hatch Not Closing451 Fortwo

Your 451 glass hatch won't latch closed, it just springs back open. There are 4 parts to this mechanism. The main catch is what grabs the loop on the glass hatch as you close it. Spray some penetrating lubricant into the mechanism and manipulate the latch back and...

Normal Mod 451 Headlight Projector Fault451 Fortwo

The Headlight Aims Down And Won't Adjust Up This is very common on the 451 fortwo. The projector becomes loose inside the headlight and because the front of the projector lens is the heaviest part, the dipped beam will aim too far down and no amount of adjustment will...

There is an easy way and a less easy way to retrofit heatet seats to your 451. It really depends on the year your smart was made. From around 2008 to 2010, smart started to include all the wiring for the heated seats so all you have to do is plug in a few things....

Premium Mod 451 Heater Fan Brushes451 Fortwo

451 Heater Motor Brushes For some reason, it's mainly the American 451s that suffer with brush problems. Dunno why but it does affect non Americans as well. The standard brushes seem low quality and seem to wear very quickly. Probably because the commutator gets a...

Premium Mod 451 Horn Not Working451 Fortwo

It has taken 10 years for this issue to appear but I knew it would eventually occur. When I looked at the 451 wheel back in 2007 I could see a weak point in the system. I'm sure it'll soon become a common problem. Smart knew it'd be a problem as they changed the...
