The cars lights and door locks and dash gauge are out the battery is new as well as the altenator car runs fine i checked the fuses there cool too any tips?

all fuses all boxes checked. cab and engine bay?
well we scan all modern cars first./ it will show DTC errors. like dead cluster communications? or?
do not skip scans on cars, or go broke guessing endlessly.for sure.

as its a used part it may not be in working order , check the charge rate by putting volt meter across the battery terminals when engine running , the reading should be around 13.5 -14 volts , if not then check the alternator belt is tight enough and retest the charge if lower than 12 volts then the alternator is useless , a non charging alternator will give the symptoms you've described, th ered icon is the non charging warning light , dont drive if the check is low as will ruin your battery as well, take alternator off and get a lift back to the supplier , best to by new

Either its a bad new battery or tour altenator isn't charging it. Jumpstart it.

there's a black box under neath the steering wheel behind the panel unplug it it worked for my blazer i had the same problem it took me 2 months to figure it out i changed all the dome light switched and the fuses so i unplugged the black box under the dash below the steering wheel and it works fine now

even if you missed a plug, it should at least turn over. should not be reason why it won't start. check the fuse panels for bad fuses under dash and under hood. its possible you shorted it out when installing the harness. .good luck.... Mike

Make an scanning for faults, I suggest a electric problem with the plug connectors or fuse.

Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).

Sounds like the alternator may be missing an excitation current source.
Check the 'IGN' dash indicator lights when you turn ignition switch on prior to starting motor,
if not one of the below may be problem:-
1) check exiter control wire is connected to alternator D+ terminal (low current wire, +V with Ign on),
2) replace dash 'IGN' indicator lamp.

I had a similar problem with a 2001 Saturn. We checked every fuse and they were all fine. We finally did a 'reset' on the car's computer by disconnecting the battery and reconnecting it a few minutes later. Everything was back to normal after that.

check the relays in the engine compartment fuse panel... locate the one for the alternator and replace it and see if that fixes it.... short answer to your question... yes they can be bad right out of the box... very frustrating to say the least
