My tail lights won't come on even though all the bulbs are good and all the fuses are good. My backup lights, brake lights,and turn signals all work fine. I read something about a circuit board for the tail lamp but can't find any info (including location) or mention of this part anywhere.
My safety check has already expired and I need this fixed ASAP. Thanks for any help with this!!!

 

If the front park lights are working then the switch, BCM, PCI data bus, parking lamp relay and FCM that grounds it are working fine. I would suspect internal problems in the IPM (fuse box) or wiring external to it out to the lights. Might inspect the connections on the IPM. They're known for corrosion problems.

Thanks for the reply. Now I see that my front running lights don't work either.
I will inspect the fuse box but would love the diagram. email is

Much aloha.

 

Just sent the diagram. Since your front lights aren't working either then you have to include all in the first part of my previous post and not just the fuse box. Either the park lamp relay is bad or it's not getting ground or power as it should. Try swapping the relay with another on the panel.

BTW - I would bet your license plate light is out too.

 

Endless thanks for your help. I opened the fuse box and checked out the relays. The tail light relay was missing so I pulled the horn relay and stuck it in the empty lamp relay space. Now all my lights work but the horn won't. I switched the battery emergency turn off relay with the horn and now the horn works also. I'll get my safety inspection done today and will order a new relay to replace the missing one. Actually, I'll order a couple so I have an extra one around if I ever need it. Thanks again for making it all so easy. With the lava pouring down the mountain and right thru our lovely little town, its nice to have something go really smooth. Thanks again Cougar!

 

The relay was missing. Well that will sure do it. Any idea why it was missing? Anyway, just happy your lights are working and you're on your way. Lava? We keep hearing about it on the news. Unfortunately, mother nature can be your worst enemy. For us it's earth quakes. Hope you get some good news soon.
