Guys, I was driving last night and all of a sudden all of my interior lights went out! I have no lights on the steering wheel and no lights down the center console-including the heated seat switches. The Nav screen still works and I've got lights inside the tach and speedometer. Even my underdash LED lighting is not working.

But recently, the Nav Screen at night has been going a little darker too. The weird thing is that the Nav Screen does not get darker when you turn on the headlights.

I checked all the fuses by the Dead Pedal and all fuses are in working order!

I took it to the dealership to see if they could figure out what is wrong and they are stumped too.

Any ideas on what it could be????

 

I have the wiring diagram manual. Ill look into it and see if I can come up with anything

 

Dealer stumped huh...not surprising Try taking it to a electronic car shop that specializes in troubleshooting stuff like this. Get the bill and have acura pay the bill.

 

Thanks, please let me know what you come up with!



The ironic thing is that my underdash LED's were put in by a custom audio shop that specializes in this stuff. The dealership immediately thought this happened because of my underdash LED's.

 

Ahhh yeah the dealer will simply see that you had aftermarket work done and then they will normally wash their hands(expression) and step back and say have a nice day... I hate that crap GL man hopefully u and trance and figure somethinmg out

 

I actually have an appointment at the custom audio shop on Saturday at 4pm, just in case the dealership can't figure it out. Honestly, I don't think the underdash LED's were the cause of the outage.

 

This is a fuse---I had the same thing happen to me a while back. Check the underhood fusebox---I can't remember which one it was.

 

DWB-you are right! I got my car back this afternoon. They spent 2 days going over it. They finally determined that an underhood fuse would blow out because of the LED switchbacks. So they replaced them with OEM amber bulbs. I already replaced the amber OEM with white ones.

BUT......Buda and I installed some resistors a few weeks ago. We did that because the LED switchbacks would blink very fast, since the LED's draw less current than the OEM 1157 bulbs. So this slowed down the blinking to a normal rate.

But I noticed tonight that when I turn on the headlights, the turn signal bulbs on the passenger side light up and the bulbs on the driver's side do not. But the bulbs work fine when you engage the turn signals. It's just that one bulb lights up when you turn on the headlights and one doesn't. I'm not sure what that means, but I'm supposed to go over to Buda's on Sunday to correct this.

Glad you got it all figured out (well the fuse part) and good luck with the switchbacks.

 

Happy to help! Keep us posted on the diagnosis.

 

Will do, guys! We've got to get the resistor issue corrected for sure. Hopefully that will be done on Sunday afternoon....thanks!

 

A lot of us forget about those damn underhood fuses... lol. Glad you're making progress with your issue, Steven.

 

Thanks buddy! I didn't get together with Buda today because I discovered that I had a loose wire on my drivers' side turn signal plug-in. This was causing the bulb to only work when I turned on the turn signal. The bulb wasn't working when I turned on the headlights-I discovered that it was because of that loose wire. I'll have the dealership fix it for me next time I go in. In the mean time, I've got the wire positioned so the bulb lights up when I turn on the turn signal.

But I have a question for you guys-I've burnt through 2 sets of LED switchback bulbs. Do you think it's because of this loose wire, which caused the fuse inside the engine compartment to burn out....or both? (Basically, what has happened is the switchbacks have lost their amber lighting over time. Remember, Buda and I installed resistors so that the LED switchbacks wouldn't blink fast, like there was a burnt out bulb. I thought one of the resistors was bad, because the driver's side turn signal wouldn't light up when I turned on the headlights, but it was the loose wire).

Should I try a 3rd set of LED switchbacks, now that I know I have a loose wire?

 

I went ahead and ordered another new set of 20 bulb LED Switchback bulbs from AutoLumination.com today. I might be nuts, but I'm hoping this set of bulbs won't blow the engine compartment fuses again, like the 60 bulb switchback bulbs did.

What do you guys think?

 

I had this same problem happen to me last night Steven. I went and looked in the underhood fuse box and found that a 15A fuse was blown (can't remember which one it was). I replaced it with another 15A fuse and got in the car to check if the signals would worked.
I turned on the hazard signals turned on once and stopped working. So I go back under the hood and guess what... the new 15A fuse I JUST put in was blown! I replaced the fuse with a 20A just for now b/c I don't want to get pulled over for this. The blinkers work with the 20A fuse but not the center console. Can you give me any feedback Steven?

 

Figured out that there are 2 fuses that was blown in the fuse box one being the hazards which is the 15A and one labeled small lights which I believe is a 10A. Now I thought everything was working and now my right switchback is blown. I checked the bulb before I changed the fuses and when the hazards were on it worked. Now that I put the new fuses it doesn't light at all. Can anyone help me?

 

Steven, how are the 20 LED switchbacks working now?
nYmALu, check the wiring to make sure nothing is shorting out. Also, put a 15A fuse back in that slot instead of the 20A. Remember guys, fuses protect the wiring, not the devices. I'm willing to bet you have something shorting on that wire. This can be a bitch to troubleshoot. Look for symptoms more detailed than what you have already described. What lights work when? What lights go out? Be methodical and detailed and you should be able to figure it out.

 

Guys, I have not installed my 30 bulb LED switchbacks yet....I know, it's been waaay too long. But I wrote to AutoLumination.com-they said the 60 bulb LED's will NOT work in the TL. The 20 bulb LED's were too big to fit through the housing, so I sent them back and got the 30 bulb LED's. 2 days ago, I bought and received LED protectors from AutoLumination.com. They were $2.00 each and are supposed to protect the LED's and help them not burn out. So Buda and I are going to install them either this weekend or next week.

DWB, my ACURA dealership did replace my turn signal harnesses. So I probably could have put these new LED's in without anything else and I bet they would have worked! But I'm trying to be practical and do it right!

 

I replaced the 15A fuse and when I did that the right switchback blew out. All the lights in the car work except the right switchback. The right rear blinker and side markers all work just not that R switchback. I checked the wiring and everything seems to be connected but I didn't take the bumper off and check. I have the 60 LED switchbacks and might order the V-LED type 2 switchbacks. You guys think I should try switching the bulbs and see if it is a lose wire and not the bulb itself?

 

nYmALu, AutoLumination.com told me the 60's won't work with the TL's. You might consider switching to 48's or even 30's. But the 20's won't fit in the headlight housing, so your choices are the 48's or the 30's.

 

I don't understand. I have been using 60 LED for a couple of months.

But yesterday while driving in the colorado blizzard, my parking lights and interior center console went out.

checked the fuse and noticed "Small Lights" or 10a was broken. I replaced and as soon as any power, it blows again...

pretty frustrated.

 

Okay... Did some troubleshooting. For those whom have the same problem, you will need some free time and extra 10a fuses (for me they are red and will need ~x4). Here's what I did.

1) Tore the front apart. (Front bumper)
2) Removed the lights and replaced the fuse.
3) Turn on car and lights worked. The side markers and rear indicated so.
4) Checked wires to see if I can find an obvious problem. Didn't find anything really.
5) Placed one switchback in the turn signal socket (driver side) and turned on the car. It blew the fuse immediately
6) Removed the switchback and put the other switchback in it's place. Replace the fuse and turn on the lights again. This time it worked!
7) I then took the "good" switch back and plugged it into the passenger side turn signal socket and turned the car on again. It worked.
8) I removed the "good" switchback and put the "bad" into the passenger side socket to test if it's the connection or bulb. The "bad" blew the fuse immediately as expected.
9) Just to be anal, I swapped the switchbacks bulbs with the connectors and tested again. It definitely did not like the "bad" one.

I think I'm very lucky to have one "good" switchback to come to this conclusion.
So I can only assume one switchback is bad and causing the problem. Anyone please chime in if you see a flaw in my logic.

Thanks.

Good troubleshooting, Kevin.
Contact your vendor and tell them exactly what you did. Also ask about the LED protectors Steven mentioned. They seem a a cheap peace of mind type thing.

 

Good troubleshooting indeed Kevin!

I forgot to tell you that in the midst of me blowing 2 sets of LED switchbacks, I discovered that one of my wiring harnesses was bad-it was causing both the switchback bulb and the regular bulb to short out. It was replaced under warranty by the dealership. So the 30 LED switchbacks are working fine now.

I bought the Protectors, but have not put them on yet. And you're right, they're only $1.99+shipping. But we thought we might have to take off the front bumper to get them installed. I said, "Forget It"-I installed the 30 bulb LED switchbacks-just to see if they'd work. So far, so good!

 

lmfao

 

Guys, I went ahead and installed my LED Switchbacks WITHOUT the protectors-and so far, so good! I had a short in the wiring harness, so that got replaced by the dealership. Buda was going to help me install the protectors, but he thought we might have to take off the nose of the car to get them installed. So I just said, "forget it, I'm going to try them anyway."

No problems so far, but I DO have the resistors installed too.
