I have a 93 DS 5 speed manual the person who had it before me was wire cut and splice happy or something In the cabin. One day last week I hit a bump and all my power to my dash was gone, The turn signals stopped working and I cant figure out what it could be...What should I do...I checked all the grounds...everything seems fine there but im stumped on the wiring...Thanks in advance for any help or ideas. If you want more info just let me know

 

also the power window controls arent working either

 

check the wiring coming off your fuse box, make sure all the connections are solid, also, check your accessory ignition wire. is your radio still working? dash lights? what do you mean by ALL your dash power? like everything? your best bet is if everything went out, you lost a main power supply line, probably a fuse under the hood, or a wire that has a faulty crimp/cut wire. if you can get your hands on a schematic that would be best

 

Ok heres a bit more I found out about this..I dont think its a relay i think its in the wiring harness to the dash cluster...The turn signals work if the headlights are turned on. The rpm gauge will work if the headlights are turned forward but the rpm gauge dies if the signal is turned on...havent pinpointed the exact solution yet though
