Interior lights

[02AleroEco]

ok so, my map lights and dome light are usually off when i drive. obv. but now even when i drive and have the dome light set to door, it stays on, aswell as the map light under the rear view mirror. yeah they stay on, even when set to off. whats wrong??? the fuses were changed but still happened. is it a relay?

[AleroDrime]

um... do you have the dimmer switched pushed all the way up into the on position?

[lonzoj90]

I'm having the same problem. I unhooked the cord on the back of the rearview mirror. I havnt figured out a better fix yet

[bdyman]

its controled by the door latch, replace the door latch problem fixed
ya know you open the door the little light goes on

or sometimes the contact points that hold the bulb get loose, check that too, or check the dome light if its not the door latch
any service vehicle lights on

[AtomicX]

I have LED's in mine and they always stay on but they are very very dim and faint.

find a wiring diagram for it, grab your multimeter, and start checking.

Probs start with the door latches... I forget.. do our cars have a chime for every door if the key's in and door opened, or just driver's side? Same with keeping the radio on. If the radio turns off right away when the car gets shut off.. it's the driver's door. If not, IIRC, that eliminates the driver's side door at least.

i will check the dimmer again.
and no, there are no service lights.

halogens have a high amount of current needed to "turn on" leds do not.

the residual in the circuit produces pin point light in leds... its just bad circuit design on GMs part.

the damn dimmer switch was set to on.. haha
now on this same topic. my dash, hvac, and shift console lights do not work.. fuse is fine. i realized that putting in led bulbs of a diff wattage blew something. can i repair this?

[cherrington17]

um...

leds of a different wattage? leds use LESS power, not more. more = blown fuse. less = nothing

what lights did you change? double check fuse in the top right of the passanger fuse box, as well as the ones under the hood.

[jayson_waltz]

ok this is gonna sound dumb, but since you somehow left your dimmer switch on all the way for the lights to be on, did you by chance have another brain fart and turn the dimmer switch all the way down now?

LOL thats just a bad day.

[02AleroEco]

LOL thats just a bad day.

ive had a bad year hahaha.. but no they havent worked for awhile, and ive been trying different things. the switch isnt the issue for this one. and if the fuse in the pass side box was blown then the dome light and map light wouldnt work, now would they haha..
as for the hood, what fuse(s) do i check? i always went by the assumption that the pass side was the only interior light fuse.

[cherrington17]

no, there is definitely one under the hood too. don't know what # it is. use the search.. its been covered before.

also.. you DO know leds are polar, right? as in... only work one way...

[Nate's Alero]

also.. you DO know leds are polar, right? as in... only work one way...

i found that out the hard way once, put together many many LED's, and i just, put them together, whoops

[02AleroEco]

they were the 194 led bulbs.
i had them on as bright as they could go, then one started blinking constantly, then they all just went out, and even the stock ones wont work, which is why i figured i fried somethin, cuz i honestly never knew that there was a fuse in the hood for the interior lights, but im looking it up as we speak then im gonna go check

[02AleroEco]

So it was a maxifuse, #2. and it was fine, i tried switching with another maxi, and everything still worked the same like before, still no dash or hvac lights...

[cherrington17]

then you have a short.

now just need to know where...
1) check voltage at the bulbs
2) check voltage at the dimmer
3) check voltage on the passanger side fuse

see where it is that your losing it.


and flickering means 2 things. the LED is burning out.... or you have a bad connection. bad connections usually mean a bad ground somewhere.

[02AleroEco]

voltage at dimmer was fine, and its a new fuse, ive yet to check voltage at bulb.

[cherrington17]

i don't mean check the device... i mean check the connections for voltage. if there isn't any, the short is before that spot, if they do, then its somewhere after.

[02AleroEco]

so at the harness? because ive checked that, and there was voltage to it.

[Cliff8928]

Do the dome lights shut off in the normal amount of time when the car is not on?

If you push the "lock" button on the door with the doors closed, do the door locks lock on the first press?

[02AleroEco]

i don't mean check the device... i mean check the connections for voltage. if there isn't any, the short is before that spot, if they do, then its somewhere after.


yeah, at the harness? it was fine. so where after that could it be? like a resistor or something?
