head unit/overhead console bulb/alarm chirp do not work

[anlbdz]

First time posting here and semi-DIYer here, so I apologize if i mislabel parts.

 

Here's the situation:

 

99 legacy L sedan

 

I installed an alpine head unit and speakers years ago when i purchased the vehicle and have not had a problem since. Within the past few days the audio would go in and out while the head unit remained playing. I could hit the side of the middle console and the music would come back on. I figured one of the speaker wires behind the unit was coming loose.

 

So, I disassembled the console last night, pulled out the head unit and jiggled the wires around, removed and reconnected the sockets and what not. Success, or so I thought so. The audio was again working for a good 10 minutes without fail. When putting things back together I noticed the overhead interior light (not the dome, but the map reader type light) went out randomly. Since it is not connected to the door, it should not go out, and never has before (i've accidently left it on and it ran the battery down..). I didn't think too much of it. But when i got the console back in place and put together...the stereo won't power on...

 

I took it back out and re fitted all the wires...still nothing.

 

It was about 1 in the morning so i decided to work on it another day and resort to my ipod today. But something else happened as i closed my car door I noticed that the normal chirp i hear when the door is locked did not go off and the blinking red security light was not blinking. I checked the fuse for the radio but it seems to be fine. Funny thing is...the cigarette lighter still works fine.

 

is there a connection to the map light going out, the head unit not powering and the chirp/red light not working anymore?

 

Any help would be greatly appreciated (i'm a courier....so I'm in my car a lot and need a radio)

Welcome to the USMB.

 

Not sure if you got this figured out, but it really sounds like a fuse or possibly a ground issue. I'd suggest checking all the fuses in the main fuse box and the box in the engine bay with a multimeter. There may be a separate circuit with a blown fuse.

 

Other possibility could be a ground wire loose or a short. Those would be more difficult to track down.

 

You can download the 99 legacy factory manual from me. In there are wiring diagrams and you may be able to look at them and try to determine a common power source that may help in narrowing down where to continue looking.
