1989 Rx7 Dash Lights and Rear Taillights not working?
well i finally bought my FC off a friend...
just a couple simple problems...
first of all the Dash lights dont work... actually no lights work.. in the whole instrument panels... such as AC and other various componants...
also
the rear tail lights only light up when the brakes are pushed... they dont work at night time when iam driving with the headlights on... only works when brakes are pushed...
anyone got the solutions for this before i attempt myself and screw it totally up...
lol
btw anyone know where i can order a drivers and passengers side door handle? i want some black ones and since the drivers side is broken i might as well get he passengers side too...

It's not the fuse........
You need a new headlight switch.
While the interior and tail lights are on the same circuit, 9 times out of 10 the fuse will be fine.
The headlight switches in these cars are a known weakpoint, and frequently fail. I'm on my 3rd!
The reason I'm sure about this is because I have the same problem. Currently my car is "Daytime Only".

Vote #2 for headlight switch/harness connector.

You know the round **** you turn for your headlights? The whole switch assembly is attached to that ****. To get at it you have to remove the "hood" over your instrument cluster.
The switch its self is screwed to the back of that "hood".

I had to replace my headlight switch two times and those things are not cheap. It is the headlight switch because my Turbo II had the same problem. No taillights and no instrument lights. Pain!!

also while iam on a roll here.. right side window does not work at all... but left side works fine... even when i try to use the drivers side controls.. it doesnt work.. any idea?
actually.... mine wasn't the switch.... mine was the harness that connected to the switch.... one of the connectors was burned/melted/mangled, so i just picked up one from someone's parts car, and re-soldered all the connections together, plugged it back in and voila! simple enough.

i just wanna get one thing clear.. my headlights work... but the tail lights and instrument lights dont.. i just wana get that clear incase someone missed it and makes a difference.. because i thought if the headlight is connect with the tail lights and instrument lights.. wouldnt the headlight go out as well?
yep, that's exactly what was wrong with mine... my headlights worked fine, but my tails & dash didn't... brake lights worked fine. my wiring harness that connected to the headlight switch was burned out.

I am getting the replacement parts from a dude here on the forums. Just ask around and you can get the parts cheap.
Don't forget when you put the new harness in, to use a little conductive grease in all the contacts and the exterior bulbs, and of course I do recommend the relay set up mentioned above.

The instrument and taillights are the only things on the ILLUM fuse.
That is the same exact cell that is slightly burnt on my harness. Mine isn't nearly that bad though, so I didn't have to replace it.
When I looked it up in the manual, I think that is the coolant warning connector that is frying like that. It's the brown wire right next to the red and green one (dash lights).
