I have an 05 ss/sc cobalt that recently i got pulled over for my taillights not being on at night, now just before i got pulled over my cluster lights went out, cluster still works, now i checked for burned out fuses and found none. now the funny part is my headlights still go on, my blinkers in the front still work and rear, as do my hazards, and my brake lights still work, just that the running lights at night wont light up the tails, no burn bulbs either. any ideals or parts things i should trouble shoot, i could use your info, only thing i can think of is that my turn signal switch on my steering wheel, for something internal went on that.

 

The fuse for the instrument cluster lights is in line with the fuse for the marker lights, this is done so that, if the marker lights go out the dash lights go out as well - you are more likely to notice no dash lights than no marker lights

Check the fuses again, would bet one is blown or not seated fully. They don't always "look" blown either, sometimes there is a very small (and hard to see) break in the conductor.

 

so the cluster fuse in the engine bay? correct is what you saying i ll double check it

 

The fuse you likely want is labeled "PRK LAMP" in the under hood fuse box. Unless they have been used, there should be some spares in there as well, if not, grab some at your prefered auto parts place.

Never hurts to have spares, fuses seem to blow at the worst possible times.....

 

i checked the fuses and changed them with new ones still nothing. the parking lights work at night in the front just not the rear. they only light up for turn signal or breaking other wise nothing

 

i do believe there is a recall for that issue. if you pm me your vin i can check and see if it is available for you

 

could be a bad switch

 

hold ur bulb like when ur running lights are on try and jiggle the bulb... i had a connector that was bent on my car( redline) but the brakes and turnsignal worked just like ur's but 1 of my running lights did not work it was the cause of a bad connection at the point where u plug in the bulb... althouh it seems u have a more difficult problem.. cant hurt to check.

 

both lights dont work in the rear i check the connections in the back there fine

as in switch you mean the switch on the steering wheel cause that was what o was thinking. but was trying to make sure there wasnt anything else before i bought a new one, i would of just swap out the one of my 09ss/tc to the 05 ss/sc but i cant for they changed the wiring from in 07

 

should be that one, or the wire from the switch to the lights could be damaged somehow. also check for corrosion in the fuses and all of the connections.

 

found out what the problem was, ended up big the harness blocks that plug into the fuse box from underneath were dirty so i cleaned them up and hooked every thing up and she golden now.

 

good glad you could fix it

 

which block was it?

 

i dont remember off hand theres a few that clip onto the fuse box from underneath i just cleaned them all
