Inside lights stay on and drain the batterie

The radio fuse is in the fuse panel inside under the left side of the dash. It is marked on the fuse cover as Radio, clock. If the battery drains down fast, like overnight there is another problem, sometimes aftermarket alarm systems will drain the battery down. Check for any lights that may be staying on like the stop lights or interior lights.

The light is on because the system fuse was removed, this causes the control module to see a fault. either fix the system or pull the dash and remove the warning bulb.

You'll need to trace that circuit to find out where the short to ground or power drain is. Could be something inside the radio or a light switch.
You may need a shop manual to get the wiring diagrams.

Yes, all cars can do this, we call it KEY OFF phantom drain.

most cars spec list ILLEGALL drains (spec)_ as over 0.050 amperes. (50mA max)KeyOFF.

Here is a short to do list to find it. (most steps need ammeter to find it, )
1 A dark garage. find lamps stuck on, every INCH of car inside and out. go slow and look (bingo?)
2: connect the ammeter to the battery PLUS lug. see that drain? illegall? now, key off for sure.
3: now unplug every fuse 1 by 1 to find the feed that has drain. (cab/ eng.bay) unplug and put back. actions.
4: unplug all relays, same way as fuse, found it, yet? see drain go away is he goal, simple goal.
5: ok 3 or 4 finds bad feed line with drain,we then unplug all things 1 by 1 on that failing feed found above.
6: ok nothing found yet,(cause) move ammeter to huge wire on the Alternator, lub, see a drain there (BINGO bad ALT)
the below ammeter (amp/clamp) is the most easy way to find Phantom Drains. bar none

unless the scan tool scans told you what was bad ?
a Phantom drain allowed to persist can wreck the battery in just 24hours.
THE METER must DO DC amps (many do not and costs tad more for DC amps) DC CURRENT
AND A 2AMP RANGE. at least.

on my meter it has autozero button that must be pushed 1 time in current mode. to calibrate it first ,and clamp; the wire first. (better meters cost more)
I put a STAR icon to show the amp lamp test points, (battery cable and ALT) simple example.

do you need the see u goodbye notice? if it doesnt effect any running components to your vehicle. the quick fix until you have the money to have somebody chase that wiring issue. pull the fuse. then it cant drain your battery you cut off its electric supply until u can get it looked into. just a quick fix though. you dont want to keep doing things like that lol. im old school so i will run with minimal. the motor runs, im good!! :)

Your inside lights are staying on
If the fuse was blown they would be off
So forget the fuse.
Why would you replace a good fuse with
another good fuse?

It is not causing your battery to die
The problem that causes your light to
stay on is the cause of the battery drain

We can't diagnose or guess over the
internet,you need help from a friend or
repair shop

you have hot grond

It would be best to pull the radio fuse leaving it out for several minutes then replace it. tis may well fix the problem but if it doesn't you can remove the fuse agin knowing it will not drain the battery over night

pull the courtesy fuse temporarily and see if the battery still drains,if it does then it may be in the alternator
