runing

I've had the car for nearly 18 months and have had no problems with it. The only niggle is that when it's parked ( always in the garage) and the car's unlocked there seems to be a fan or compressor running,sometimes for up to an hour after it's parked. Locking the car will normally stop it after...

Morning people, on my 200T 88 I have a motor running in the n/s door pillar. I assume its something to doo with the senser in the interior light cluster. I had a look and a pipe was off in the roof ? so ive re-fitted it the best I could. What is this for and is it servicable does anyone know...
