First thing to check are the fuses for horn and lights

SOURCE: turn signals not working

I suggest to check fuses frasher devices and relays; keep in mind that some circuit is porbably in short.

SOURCE: 2001Mercedes E320. Drives fine until I take my foot off gas peddle the car is still running but gas peddle does not work turn off then on runs fine until I take my foot off the peddle what is happing

If you have drive by wire. I would check the TPS first. It's under the gas pedal. (bad location). Unplug it and plug it back it. (bad connection) see if it still does it. If so. Have the codes read. I replace a lot of these because of the location. Bad water and moisture source.

SOURCE: 2005 E320 4matic my horn signals air windows have no power and also have battery sign but I checked my battery and is good.

Either you have a main fuse blown or a main relay not working. Have you checked the alternator
