after i thought i had all the bulbs in the hvac controls replaced with leds, i hooked it back up and not only will they not light up, but all the lights in the gauges wont either. this makes it very difficult to see my speed at night. Can somebody tell me what i have done wrong. i was hoping it was just a fuse but i dont think it is.

 

did you try the fuse? Cuz I think they're all on the same fuse. I could be wrong though.

 

My guess is fuse

 

Fuse

 

fuse or dimmer <-- hey you never know lol

 

this^^^^

 

what fuse? i checked the climate control/cluster fuse and the interior lights fuse. which fuse should i check?

 

Did you,Did you really ?

 

you said u were using leds.... u make sure the positive and negatives were connected properly and not in reverse? it matters with led's

 

thiers 2 fuses for cluster @ floor console fuse block.. Fuse 7 is cluster and fuse 16 is climate control system/cluster have you checked both...

 

did u also use resistors and such? or just full throttle power

 

no i didnt use resistors. before everybody posts on how much of an idiot i am, can somebody at least explain to me what a resistor is

 

The resistor drops the voltage to one that the led can handle...the board is getting 12v and the led's most likely run at like 3.5v...unless of course you bought 12v led's then none of this matters

 

so without a resistor the led wont work? they aren't 12volt. where do i get resistors?

 

Radio Shack or a hobby store

 

First figure out what rating your LEDS are rated for.. There are many different resistors you can buy all with different amount of resistance

 

there is no such thing as a 12v led... if what ur putting on there is just the led and prongs then they need resistors. a 12v led is just an led that already has the resistor but it would have wires and stuff

lastly your leds are going to need to be small and wide angle. most are directional and trust me it makes the hvac controls look like ****. guess its better then nothing thou

 

Right now I just stuck two already wired walmart LEDs in there and put it in place to make it visible. I checked every fuse in the floor box(even the non related ones) and none are gone. I'm guessing me using lights without resistors ruined my cluster lights as well. Can anybody else figure out why the cluster lights wouldn't work?

 

no, no it doesn't.

 

still trying to figure this out. is it possible that the hvac is the middle of a circuit for all interior lights. the steering wheel control buttons dont light up either. if the hvac control system is completely removed will that prevent the cluster from lighting up?

 

If you put them in backwards, they stop current.

Yes it does...












wtf?

 

I can BS I used 12 leds that DO NOT have any resitor can take pics if you like.

 

so how can i fix this. i took all the bulbs out completely and it did nothing.

 

the hvac controls dont need to be in at all for any lights to work. on both fuse panels yank all the fuses and visually check to see if they are ok. and make sure the car is off with the keys out of the ignition

 

show me what? yes its possible to use leds without resistors in an application that uses less voltage or multiple leds wired properly. but what does that have to do with my statement that there is no such thing as a 12v led? to be honest im probably a liar. i bet there is an led that takes 12v but its not going to be a standard looking led and nothing u can just pick up at radioshack or walmart or anything like that. no offence to the OP but someone looking at a real 12v led isnt going to be asking that question. im just saying
