Side markers & parking lights don't work
 

Checked all fuses, they are all fine. (And turn signals work) I actually rather the side markers and parking lights off, but I want to know how to fix it. I was putting in led switchbacks when this issue occurred. Oh and I did install the relay for the led turn signals.

Fuse. Check again. Unless you disconnected something when you installed the digital flasher.

I put the stock bulbs back in, and I guess I'll take it to the dealership. Hopefully they won't not fix it cause of the led thing....
Does changing that relay void the warranty?

Tail lights aren't working. Double checked all fuses- they are working. Brake lights work. No license plate lights either

Is there a reason for why you haven't taken it to the dealer?

This all happened this afternoon. I don't have my stock relay and I'm assuming they'll say something about it. Granted my turn signals work fine

Anyone have any insight??
Checked the fuses again, and all are fine.

So put it back to stock and try again.

The aftermarket relay should look extremely similar to the OEM relay, I don't think they would notice. Last resort, change it to the stock relay. Not hard at all.

Maybe you fried something installing the aftermarket relay?

I installed the relay last week. Everything worked fine other than having to replace a fuse. That relay is for the turn signals, my turn signals are working.

This is the stock relay, so I can't put it back in...

I'd get another stock relay before you go to the dealer. Perhaps look up the fuses in the manual. There is a fuse box under the hood as well as under the dash AFAiK.

The fact that you blew s fuse changing a relay is an issue. You should disconnect all accessory power when doing electrical mods.

I'm still betting on undiscovered fuse issue. Pull the specific fuse as per manual.
Also inspect the area around the relay for open connections.

This is a simple fix I am sure. No multimeter required for sure.

We checked both fuse boxes. That's what I don't get, they are all showing to be fine (even using a multimeter). The relay was changed last week, and just for the turn signals. But those are working. When u say get a stock relay, do you mean like from auto zone or from Toyota? If its from Toyota I'm sure that would take forever to come in. I have no taillights, and I go to work and come home from work in the dark.
Is there one fuse for the side markers, parking lights, and taillights? The manual isn't very helpful with specifying those. If those same bulbs are working as turn signals, but not parking lights, it seems it would be a simple fix. Just want to know how lol

Oh my god i fixed it. I looked on other scion forums and someone posted that one fuse will just say tails, but it controls the side markers and parking lights too. So I tested that fuse for the third time, it was a ok. But I changed it anyway, cause I also read that sometimes fuses appear to be good when they aren't. And it worked!! Woop!! Thanks for all yall's help!! (Can u tell my Cajun is coming out lol (y'all))

Good to hear!

I have the same problem but mine was i installed my fog lamps and tapped it to my side markers. and now i changed my fog lamps t o hella optilux extreme yellows and then when i turn it on my side markers not working tail lights and license plate lights dont work also.

i would replace the fuses , theres two fuse boxes also idk if you knew so replace the fuses even if they dont look broken, unplug the battery and leave it off for about 15-30 minutes then try again

its the fuse, same thing happened to me when i changed my side markers.

its under the steering wheel, its tucked tight under it.

its the forth fuse up on the right, it controls the side markers and tails.

Looked up a lot of stuff on here, none more important than this one for getting me out of a ticket and not wasting time chasing down the right fuse. Thank you!

So I just ran into this problem yesterday. I noticed that my boomerangs, side markers, tail lights, and 4rd brake light from Fn'A Auto all were not working.

Of course the fuse for "Tails" was blown, so I went out and replaced it. All the lights started working except for my 4th brake light. I kept the parking lights on so that I can mess with the 4th brake light bulb and see if I could get it working. The 4th brake light bulb came on for a split second and then went back out...along with all the rest of the parking lights. Doh!

Maybe I shouldn't have been trying to fix the bulb with the parking lights still on? I've done it this way in the past and never had a problem, but I may have just been lucky then.

I checked the new fuse that I just installed and saw that it had already blown out.
Unfortunately the package of fuses I bought only had one 10amp low profile fuse. I did however have a 7.5amp low profile fuse, so I put that one in there for the meantime so that I at least have some lights when I drive to work tonight.

All the lights are working with the 7.5amp fuse. I plan on getting another low profile 10amp fuse tomorrow.

The only other thing I have noticed is that my alarm system no longer blinks the bomerangs and tail lights when I arm or disarm it. I verified that the 7.5 fuse is still holding up and all the parking lights are coming on as usual, but my alarm system does not seem to be getting a connection to my parking lights anymore.

I'm thinking I can take my car to place I had the alarm installed and ask them about it. I'm guessing maybe another fuse is blown on the alarm itself?

So with all that said, does anyone have any suggestions I should try before replacing the 10amp fuse again or taking my car to have the alarm fuses checked out?

Thanks for any help!

Haha. Yeah. Same thing happened to me. My side markers and DRL's wouldn't come on, but signals were working and brake lights. Driving me crazy. In the end I checked every fuse individually and this one was the culprit.
