Inside dimmer light fuse keeps popping

[Tplayer]

I started a thread a while back concerning my inside dimmer lights.
They all stopped working sometime after I had a high end sound system installed in my vehicle.
2002 Grand Prix GTP

It was suggest that the audio shop may have disconnected something under the left front dash by the emergency break.

I did take it back to them and they went over it with a fine tooth comb. They informed me that there is a 10 amp fuse in the glove compartment that was blown.
However, each and every time they replaced it with a new one it would blow instantly.

They don't know why this is happening and suggested I take it in to the dealer.

I didn't have this problem before the sound system was installed.
I guess my question would be weather the factory radio being replaced with an Alpine would have any effect on this?
Or could the kicker battery they installed in the trunk be the culprit?

I tried replacing the fuse my self and for a short time all the lights started working again.
I would say they worked for about a half hour.
Then just like that the fuse blue.
Now it blows on contact just like they described.

Does anyone have any suggestions??

The fuse blowing sounds like the interior lamp fuse. That is a lot of current being drawn or a bad short to be blowing a 10 amp fuse. 5 amps will give you cardiac arrest.

It doesn't sound like the new components but something the shop did. After all you did not have the problem before the work was done.

Taking it to the dealer to fix could be expensive. You could try tackling the problem DIY with a multimeter and wiring diagram of the interior lighting and power distribution. Also, you can pull all the interior lamps and see which one or leg of the circuit is blowing the fuse. Maybe you can narrow it down to a certain area.

What would happen if I put a bigger fuse in. Say a 15 amp or even 20?
Also do you think the amps they installed in the trunk could be causing the problem?
They did put a special battery in the trunk that is supposed to take some of the load of the car battery.

I would not recommend overfusing but you could try the 15 amp. But be careful because you could fry wiring and have a bigger mess.

Hard to say if it is the battery. Why would the additional of the battery only affect the interior lighting?
