Mondeo MK4 Kombi Left Position Lights & Cabin Light Issue - Electrical Fault?

Hello,
The case concerns MONDEO MK4 COMBI
I noticed the lack of left position lights and therefore the lack of left rear light. I checked the bulbs and they are OK. I suspected the fuses, but the manual does not mention the fuse for the position lights. So I checked all fuses and relays (all 3 boxes) - but everything was OK.

The right side lights up - the left side doesn`t. Suspicion fell on the computer, are the position controls directly controlled by the computer in this model? Has anyone encountered such a problem?
In previous models there were separate fuses responsible for the position lights, but there is nothing like that here.

ps. I don`t know if it has anything to do with it, but in addition, the light in the cabin (the one next to the rear-view mirror) does not go off when I set it to the middle position (door sensor), and all the other lights (the one above the passengers and in the trunk) go off

Please help.

The vehicle interior fuse box is powered from the engine compartment relay fuse box, namely 60A fuses (F17 and F18, if I am not mistaken - considering the position lighting). On line 50, the probably purple-green cable powers the rear left position light, and on line 39, the left position light is probably a yellow-blue cable

Have you solved this problem yet?

Hello.
Gentlemen, how to get to these fuses F17 and F18?
I don`t want to break anything
Thanks

I checked everything and it sucks. And reset helped. And I have lights Reset involves disconnecting the battery terminal for 10 seconds.

The reset didn`t help me, can you write what needs to be done to remove these fuses?

I don`t remember. And I`m far from Mondeo. What are your symptoms? Because these fuses are main fuses, probably 60 A. If they fail, more circuits are without voltage. I don`t remember exactly, but I think the wall moves upwards.

My left rear lights in the trunk lid are not on - the power is coming, the bulbs are OK, but they don`t work

I understand that "current is coming", which means that there is voltage in the bulb socket. Check if any other bulb lights up and then you have voltage. Does the voltage disappear after opening/closing the flap?

Thanks, I`ll check

Hello.
I have a problem with the rear and front lights on the right side. Parking lights don`t work. The front lights come on when I press the brake pedal. I checked the fuses and they are ok. What could be the reason?

Maybe a weight problem.

If there is a double-filament bulb in the rear lamp, it is possible that someone inserted a single-filament bulb

Thanks guys, I`ll check it out too

Hello.
I also wanted to ask what could be the reason for the rear lights in the trunk lid not working. Reverse works, but the rest does not (the bulbs are ok, but the voltage is only in the reverse bulb socket). My brother misled me earlier because he said that there was voltage in all sockets, but as it turned out it was only in the reverse socket. I apologize for my earlier incorrect information.
Thanks for the help

Maybe broken cables at the transition from the body to the tailgate, or lack of contact in some bones along the way, it`s worth checking.

Thanks, I`ll check

Hello. I noticed that my right rear and front lights turn off after about 3 seconds. Should I try a reset or is there another way to solve the problem?

Well, there`s definitely something going on with the module. On the MKIV forum they write that key 10 is the most important tool for repairing Mondeo . Reset. Just have the radio code on hand.

I have a question how to do this reset
and will the engine start without any problem after resetting?

Normally remove the battery terminal for 15 - 20 seconds. Then put it on. It will fire up without a problem.
