I'm sure this topic has been discussed at great lengths, but I have a hard time finding applicable info. My turn signals don't work...at all. If I push the hazard light button all signal lights turn on but don't flash. I replaced the flasher unit at the fuse box and checked all the fuses with no improvement. The rear lights are new. I noticed that my front side marker lights weren't working even though the test light shows power to them. Eureaka!! I ran a new ground wire and this made my side markers turn on, but when i turned on the turn signal light it instantly blew the fuse. I don't understand why my side markers would have anything to do with my turn signals. The turn signals do light up with the running lights so i know they recieve power. I also noticed that when i was testing wires for power coming off the turn signal switch, when i touched my test light to a specific wire my test light started flashing and I could hear the flasher clicking as it should when the turn signal is on.
