agree with zip and wetry they gave you a good start or you could seek help from your mech
After checking what wetry suggested , if not resolved , please reply here with what info you have available and what tools/test equipment you have , if you are doing this yourself,so we know how to guide you. Let us know how many fuse boxes you checked and their locations.
I have checked the fuses and they are okay. I also observed that all the gauges are not working including the tachometer and the speedometer , on putting a launch diagnostics machine, it gave me these codes: U0155 and 86-01. Please I will also like to have a soft copy of the manual and also the wire diagram of this vehicle.this is the VIN: 1HGCP26878A018004. Thank you
