OK I just replaced my ignition switch in my 95 z28. I inspected the pig tails and the old ignition switch, and there was burn damage but it wasn't the worst ever. I hooked all the lines that i unsnapped together. Started it back up and everything works perfect EXCEPT turn signals, a/c blower motor and coolant fans... Anybody else had this problem? Does anyone think it could be the pigtails that plug into the ignition switch? Or could it be the ignition lock and cylinder?

 

Check the orange wire at the ignition switch. That wire feeds the power to radiator fans relays, turn signals, HVAC switch, backup lights, rear defogger relay, and AIR pump relay. Sounds like the connection at the switch is bad.

 

The orange wire from the Ignition switch (conn A - C1, +12 in run) feeds the Fan Relay, ABS, air pump relay, HVAC, and turn/backup circuits. Each circuit has a separate fuse (total of 5 fuses) so it most likely looks line the switch or wiring for all to fail.
