Thanx a lot. I'll try to seperate the open/close sections into functions - good idea (havent a clue on how to do it but I'll figure it out - can´t be too hard)
Also - Great input on the temperature gap. My mistake... if I dont have a gap the hatch will open and close contiuously... 
No need för that.
The part with powering the servo with an alternate power source is a little bit over my head... I think. I really happy that I'm able to do a servo sweep at all I'll try to do a schematic or just take a picture of it...
