So my battery and alnernator went a few weeks ago. I replaced both at a chevy dealership and paid alot. They also said 2 of my turn signal lights went as well and replaced them.
So shorty after the weather went super cold and i noticed my gas gauge going crazy...flipped all the way past the full juat under the E! - since then it fluctuates all over and still isnt working right.
Another thing is my headlights stay on sometimes after i turn the car off. - i keep turning the car on and off many times....and thankfully get them off( and i dont know tho if they go on when i am sleep.) I only notice this at night time tho.
Do replacing the battery and alnernator have anything to do with these issues?
I did have a problem with no headlights a few months back - i read online about replacing a relay and that worked!
I am scared to take it back to the dealership and have to spend alot more on this older vehicle - but i would if it may have something to do with what they replaced. Any ideas

Hi Christine. Thanks for contacting us today. Typically, replacing a car battery and alternator would not cause the random electrical issues you’re experiencing on the Trailblazer. In most cases, what you are describing is an indication of a faulty electrical relay or an exposed wire that is creating an electrical short. It’s also possible, especially if the turn signal switch was replaced, that the headlight switch is also damaged. You don’t have to go to a dealership for repairs to be completed or this issue to be diagnosed. You might consider having a professional mobile mechanic from our team come to your location and complete an electrical problems inspection first. This will permit them to determine what repairs are needed to resolve this problem.
