My turn signal sometimes doesn't flash, but just stays lit. I've noticed  
that this mostly happens while the car is tilted to the right. I assume  
that this is due to the flasher relay being worn out?

I've tried to locate the flasher relay, so I could test and replace it,  
but it doesn't seem to be anywhere under the hood. Could somebody help me  
with a hint about the location?

Thanks in advance,
Christian
