1996 Savage. After replacing the turn signal indicator relay everything fired up perfect twice, but now I get NO power or lights. Is there a certain fuse I should check? Where is it?

One Side of the Turn Signal Lights Doesn't Work. ... You may be dealing with bad bulbs, a bad flasher relay, a faulty turn signal switch, or a bad wire or connector between the flasher unit and the turn signal switch.

Check that all bulbs are working, if one of the indicators light is gone it will tick faster.

When this happens usually you have to replace the indicator light relay, you find it in the fuse box.

Turn signals use what is called a flasher to regulate the speed at which the lamps turn on and off. Usually mounted in the fuse box. I have attached the replacement model for a 1996 Roadie. Should take all of 15 seconds to replace.

My first guess would have been the turn signal switch, which you said you replaced.
You'll have to get a wiring diagram of the switch and start testing wires for power out of the switch. Could be a problem with the main harness going back to the rear of the truck, or a ground for those sockets.

need to replace multi funition switch

check all the bulbs, make sure they have the same back. if the backs are slighty different or alot different they will send power back to relay in the wrong way, causing the problems u are talking about. if they are the same, u have a power wire grounding out from the rear signals.

There may be a seperate flasher relay for the turn signals. usually located around the fuse block.

ecc and fuel pump relays good? when the engine is turning over, does the ck engine light go out? if not the PCM isnt getting a crank sensor signal. Power and grounds all ok at pcm?

you need to check your fuses if fuses are ok locate indicator relay and check it has a live and a good earth if so open the relay and you should see a bad joint inside if this is the case you can either solder it back up or sometimes they are burnt out and need to be replaced if the relay is ok check the hazard switch

check the headlight relays under the hood also fuses under the hood and in the interior fuse pannel.
