My signal lights do not work, as well as the dash signal lights Is it a fuse maybe?
Probably a bad relay.
But check your fuses first for sure. Sorry for the double-post, accidentally hit Submit. Not sure on the 300M, but on most cars, the 'body control' fuses and a few relays are located in the block inside the car around the drivers kick panel or up under the steering wheel. If you can't find the block there, then check the one under the hood.
