About that trunk light.... I confirmed that both door and trunk light switches are properly functioning.

I managed to locate the trunk light switch for '93. It's part of the trunk latching mechanism. You will see the switch on the underside of the trunk latch if the plastic trunk trim piece in the front is removed.

I also see where I erred with respect to thinking something was wrong with the interior and trunk lights. The errors all came about due to a lack of understanding on my part as to how the trunk and interior lighting functions. I did some poking around on some other threads which discussed the trunk and interior lights a bit. Upon running some tests I confirmed the following:

- The trunk light switch does not open (disconnect) until the trunk is FULLY closed. Because of the battery drain, if I don't plan on driving the next day, I pop the trunk, disconnect the battery and simply close the trunk partially (until trunk latch lever clicks) so that when I do go to drive I can easily reconnect the battery prior to hopping in the car. As such even though I had the trunk light electrically disconnected, the switch in essence was still closed (connected) indicating a trunk is open state.

- If the interior lights are put in the door/trunk controlled (center) position, the trunk switch will also control the interior lights. That is to say when the trunk light is on so will be the interior lights.

- Both the interior lights and the trunk lights are on a timer. Once the doors and trunk are completely closed, the lights remain on for approximately 16 seconds whereby then then turn off.


Once I addressed the above, I then determined all is ok with the trunk and door open/closed switches. With the battery reconnected, I simply turned the ignition from off to the on postion and then off again. The CCU fan fired right up (that ****ing CCU fan). I left to do something else for about 25 minutes. I returned and the CCU fan was still on. Taking this another step further I got to thinking if the CCU fan has a dependency on door/trunk open/closed state, perhaps the doors need to be in the locked state too (first test doors were unlocked). I did so and returned about 30+ minutes later. Yep still on.

Good news, I understand how the trunk interior lights work and have ruled that out as a reason the CCU fan is still running. Bad news, the CCU fan is still running...

I do know that my remote central lock system and I presume alarm? was replaced with a Viper setup (found it poking around underneath the radio). I wonder if by chance installation (or perhaps not quite correct installation?) of an aftermarket door lock alarm set up by a PO would cause the CCU fan to run continuously?
