Hi I'm having problems in my Cl7 Honda Accord. When I open my drivers door the dome light or courtesy lights do not come on, but the dome light comes on with the other 3 doors. I have checked all fuses and fine also door jamb fine. I recently took door panel off to look and see if anything stood out but nothing. A few months ago I took my car to an auto spark to see if he could fit a navi system to it but he couldn't. So I looked behind the my standard head unit and he has cut a red wire from the harness! I tried to reconnect it but when I turn on my headlights the radio night display turns of so I have left it unconnected so I can see the radio screen. I cannot get my door courtesy lights to turn on. I have tried the lights on a battery in their factory light bulb holder and they light I'm goin nuts here trying to get them to light but nothing.

Plz help
