Just joined in hopes to better understand my car with the help of others

 

Welcome, what kind of car do you have?

 

a 2007 Chevy Cobalt SS S/C

 

Awesome! Post some pics of your car!

 

 

never realized this is all I have saved

 

Nice car! Looks clean!

 

I wish it was it has a oil leak I think it needs a new clutch and motor/trans mounts the interior was filthy the sun roof don’t work most of the electronics didn’t work at first but suddenly sprung to life except for door lock buttons, sunroof still don’t work and some steering wheel functions and reverse lights sometimes go out I think it’s a bad reverse light switch and it just stopped boosting over 5 psi no too long ago also a nearly dent on drivers rear from first owner

 

My 05's door locks went out. They weren't the best built cars. Fun cars to drive. There is a ton of info on this site. If you can't find it don't hesitate to ask in LSJ section.

 

Thanks I’ll keep that in mind

 

I wonder if you have a bad ground or relay somewhere. Intermittent electrical issues like yours sounds like a bad connection. If you're only boosting to 5 psi it is most likely your bypass solenoid. When the solenoid isn't energized it defaults to bypass position. Because of the other electrical issues you are having I am going to guess the solenoid isn't getting energized because of bad connection. Easy to check with test light or voltmeter to verify you don't have power to the solenoid with key on (probably engine running?). If it does have power it's likely your solenoid is bad. If it doesn't have power its either your ECU commanding it to bypass or a bad connection.
