installed new stereo, now no tail lights etc...

I have a 2000 Malibu that I have recently replaced the factory stereo with a new sony stereo. Since then I now have no tail lights or instrument panel lights. My check vehicle light is now on as well.. help, im sorry if this is a newbie question but im stuck..ive checked several fuses but do not know which ones would be relevant for me to check. please send any suggestion or help, I would greatly appreciate it..

Cheers,
Matt

Most likely you blew the Park Lamp Fuse. It is in the underhood electrical center. Fuse #45. It is 15 Amp minifuse. That would be enough to turn on Service Vehicle Soon indicator since the Body computer would be able to sense the fuse being open.

Perfect fix, I replaced the fuse and all is good. Thanks for all your help I sincerely appreciate the help.

What happens if you replace the fuse and it keeps blowing?
