Can anyone help please?
When the engine lid is opened, the light does not come on, but if I open one of the doors it does. Also when I open the front boot the interior lights come on (but the front boot light doesn't).
My guess is that there is an earth fault with the engine lid light and the circuit is being made when I open the door. For the front i'm guessing the +ve supply to the light is the problem or the bulb has gone as the circuit is being made to bring on the interior lights. Am I on the right lines?
Also can anyone explain how the system is supposed to work regarding what lights come on when what is opened?
I have searched the forum, but can't seem to get the right answer. If it is there, please bear with me, it's my first technical question here![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)

When you open the door the interior lights should come on and go off either when you start the car or by timer.
If you turn off the car then open the door the interior light should come on and go off by timer after the door is closed.
When you open the frunk (front trunk) the frunk light should go on and the interior lights should come on, and go off when you close the frunk.
The engine lid is independant on should work with the opening or closing of the lid only. AFAIK at least that is the way it works on my 91.
Perhaps a short or malfuctioning door switch may be your problem.
I also found a short in one of my interior lights that I fixed by cleaning the contacts in the switch part of the light and now seems to be working proper.
Also when the boots for the door switch get old they get hard and wont allow the switch to opperate normally.
Could also happen to the boots on either one of the lids.
Sounds like you are kind of on the right track, and I would say the frunk is working correctly and maybe just has a bulb out.
The engine lid is perhaps grounding on the body somewhere causing the interior lights to come on.

Open / close doors, or rock the interior light fixtures = cab lights on / of.
Open / close lids = respective compartment lights on / off, although there is a common problem getting boot light to go off by means of the contact switch.
Maybe the more contemporary timer operation was an option or an improvement with later models?

The frunk light switch is tied into the alarm system also (at least on my 92). To test: pop the frunk but don't release the safety catch. Lock the doors, and the alarm is activated (LED's on door blink). Open the frunk, and the light should come on (and interior lights) and the alarm should come on. Loudly.
I think I read this test sequence in Adrian's book?
Perhaps the engine lid light/switch is tied into the alarm system also?
These cars and their intricacies continue to amaze me.

ok...perhaps very strange but mine is different also....the engine lid light (gone and no light on my RSA lid/spoiler) only worked when the frunk was open.... both lights worked by the front switch located near the hinge on the passengers side frunk lid...interior lights were not tied into either lid light at all.

Thanks for all you responses, now i have something to work on.
Most important though is that I now know what to call the front boot/bonnet - a frunk!
