ok, possiable stupid Question...

and yes I did use the search button to no avail...

what is a Logicon? What does it do? and also, my Heater and my Sunroof both stopped working while on the way to a meet and then suddenly started working just fine agian... its happend twice. The "Open Door Beep" started beeping strangly as well. Could the Logicon be whats causing it? A friend Suguested it. Ive never heard of a Logicon before.

Logicon (The climate control unit)

Ran it by Google... "Logicon rx7"
It puts the lotion on the skin

Its the Climate Adjustment Box, they are expensive to replace. There is a superficial diffrence between the S4 and S5 once IIRC

MrFC3S

What about if the logicon stops working(compleatly) and at the same time, my Sunroof stops working, but then somtime later, they both magicaly come back on... any ideas? The sunroof motor isnt wired into the logicon's eletrical wireing is it?

ah the electrical curses of the FC3S... it may be a wire close to the frame that over time has rubbed the insulation away and you got a short, then *bump* the wire moved away from the frame and the short no longer existed. find the worn wire and re-insulate it and you problem will go away for now.

No a short such as you describe would blow the fuse. If you look at the wiring diagram, you'll see that both the things that are not working are on the 2nd igntion wire...

Pointing out that either he has a bad 2nd ignition wire connector at the steering column or that he has a switch that is starting to fail.

MrFC3S

So what this is saying is that the Ignition Switch is going? Ill check it(now thinking about it, i think it started when I started the car...) Thanks for the info...

Icemark

see (as the image shows) there are multiple wires that are powered by the ignition switch. Acc, Ignition 1, Ignition 2 and starter. Ignition 2 has the things like the heater blower and power windows/sunroof... basicly things that need to be on while the key is on, but not while cranking to start.

Its not uncommon to have the switch contacts start to fail on the Ignition 2 due to the load put through the switch, and the Off while cranking (creating a ON/OFF/ON cycle everytime the car is started.
