I replace the factory radio with another radio and now the car won't start and I have headlights only & no power to the interior of my 2000 chevy cavalier. No dash lights or anything but the headlights. Tries to start then kills itself.
Any suggestions?

I went through around 6 months with a BIG system in my cav. One day I was rewiring something n it just quit n said loc...now I fixed the lock it still won't peep a noise
????

I recently just did a stereo upgrade from factory system to aftermarket pioneer Bluetooth MP3 and I'm not sure if this has anything to do with it but after doing so my car all of a sudden won't stay on after starting it it just stalls out right away every single time I will check the fuses they are all good I've cleaned out the air intake of any fluid I just don't quite understand what the issue is I understand the mass airflow sensor could be the issue but I would like to get somebody else's opinion

The AC is blowing hard in the bottom , but not alot of air coming out the front panel, trying to see watbi have to do, take stereo outvto get to it, thanks for advice !
