Ok I have a 92 Z28, the map lights, door locks, rear hatch and dome light will not work. I have changed the circuit breaker, nothing happened... I don't know, where to go from here the Fuse box circuit breaker I changed is the PWR ACC that is the label for it... Please some advice there is nothing on Google about this.

 

Courtesy "ctsy" fuse, yellow, 20 amp.

 

I cant find a CTSY slot in the fuse box on the drivers side fuse box... is there a different place for this??

 

Perhaps the lettering has worn off. It's near the circuit breakers and the brake and tail fuses.

 

thanks ill check it out

 

Thanks but there was no CTSY fuse on my car it was labeled ACC I have no idea why but your location helped me out!!
