For anyone with the patience to forgive my lack of searching, can you give a one-liner description of each of these items in the boot back wall.I know number 3 is the sun roof motor with manual crank at the bottom, and one of these is the ECU.

2 and 5 seem similar, but almost like my 5 is missing or has a broken cover?

Appreciate the help. Once I know what to call them, I can then do my due diligence and search to learn more details.

Need the pictures

haha! yeahh. an image would help!

 

Sorry. Learned cut n paste of image does not work 😂😂

 

the annonized gold cylinder with the red wires attached to the ECU on the far right is supposed to be an Altitude Compensator, you know, when you're flying.

 

#1 is the Interval Meter, which makes your Oxygen Sensor light come on every 30k miles

#4 is the Fuel Interface Unit. It takes info from the ECU and converts it into a language understandable to the trip computer...so fuel economy measurements can be displayed

#6 these are the BFMs. Bulb Failure Modules.

#7 is the ECU

#8 is the altitude compensator, as Jose mentioned


Not sure about #2 and #5. Not ringing any bells. They might just be pressure relief valves for the cabin? I'll do some mulling

the vents on the left and right sides of the sunroof motor are just that, VENTS for the interior air pressure when you shut the doors with all windows closed they are pushed open by the air pressure inside the cabin to release or expand the air pressure. Sort of like a pressurized aircraft, the air needs to go somewhere, so it is dumped into the trunk which serves as an expansion or "holding" tank. Something like that.

The opposite action takes effect when you shut the trunk lid, the vents are forced to the sealed position, preventing any air from entering the cabin.

If you feel any "air resistance" when you close the trunk lid, that's what's happening.

 

Thanks!!! Great info.

 

Are those vents aka "cow bells" I've read of??

As to vents, there is an opening in the boot floor. And vents under the rear valence. They might be squashed. Mine were. But, easy, in my case, to fix. A flat bar to prize them out worked just fine.

I did not remove the side valences to get tot the tank drains. I pried out the rubberoid plugs. Ruined them doing so. considered various fixes. Decided none needed. Best to let any errant water out...

Geez, this was the dark ages of automotive electronics huh.

 

Carl, no, the 'cowbell' vents are in the tray below the rear seat package shelf.




Yup ! Been there !


Drainage is good.

The area under the tanks can accumulates loads of dirt and debris....which covers the bottom of the tanks. Not good.

There are access panels in the wheel wells that can be removed to scoop out/hose out the under-tank areas. I recommend do so every-so-often.

From memory....ha ha....the side valences do have drain holes but they're usually clogged up!

Everything starts somewhere Mad. We also use to make cars run without any electronics at all, imagine that!

 

Oh no, I was saying that the electronics predating this were more elegant and quality made than these, and the ones following as well.

Imagine that? I still have race cars that have to be push started because they don't even have batteries on board.

Electronic ignition is about the only thing i recall cars needing.

 

the tank panels or "quarter panels" already have a drain for liquids, water or gasoline. It is a small cutout or opening at the lowest point of the rear of each panel.

The large access hole is to be able to drain the tanks (small drain bolt), and/or remove the large filtering mesh, (large nut).

if you leave that access hole open, you are not creating a drain but creating a way for debris, water, and critters to get in there and rust the bottom of the tanks, not to mention mice chewing on the wiring loom that is clipped to each tank's seam lip.

It is simply a bad idea to leave those holes open but it is your car and you do as you like.

In my car, I removed both panels and sprayed their inside surface with truck bed waterproof coating. then I installed a finishing plastic Plug from the outside, which is removable if I need to drain the tanks.
