Dash Lights

I have a 2008 chevy cobalt ls 2door, i recently put on halo headlights and it blew the fuse for the dash cluster lights and the tail lights, i replaced the fuse with a 25 instead of a 10 and all went well then my dash lights went out again but my tail lights stayed on i still tried to replace the fuse and nothing happened, they have been out for a while and i have no idea whats wrong. Please help i cant see how much gas i have at light lol!!!!

Just wanted to include that the odometer, temperature, even shifting plus sign, seatbelt warning sign and even ebrake lights all work it is just the lights for the RPMs, Speedometer and gas!!

Never use a bigger fuse than a system is rated for. If it's blowing, that means there's a problem that needs correcting. Adding a bigger fuse is just asking for a fire.

Sounds like some of the bulbs in your cluster are done.

I changed the Park Lamp fuse under the hood. and well when i replaced it with the 10 it was supposed to as soon as i turned the car on and the auto lights kicked on the fuse blew so i tried a 15 still didnt work the 20 worked for a little then blew and the 25 is working fine its just the inside lights, I checked the majority of the bulbs and not one was bad. A guy i work with said from using a higher fuse i probably shorted out one of the wires

Cluster fuse is in BCM fuse block, it's 10A never increase a fuse value, that's asking for troubles.

If your blowing the parking lights fuse, you probably have or had a wire touching some where it shouldn't have been. This happened with me before, during the same process. I was wiring my halos and LEDs and didn't disconnect the battery like I should have. Since you replaced the fuse with a 25 amp fuse you may have already done the damage. It could be something as simple as chaffing or broken wire, or I could be something like you have blown the lights in the cluster, or damaged/fired the portion of the "motherboard" in the cluster that controls those lights....

Yes, unfortunately, you'll need to trace everything from your headlights back for shorts, burnt wires/parts, or damage. Hard lesson learned is...never fix electrical issue with larger fuse. It just extends the problem and you're lucky the car hasn't caught fire somewhere.

Don't beat yourself too bad tho, we've all been there. Electrical issues are frustrating, but paying attention to detail and following schematics really helps. Hope you find your e-gremlin.
