I have read here sometimes about that viewing window for the air-con unit and how you're not supposed to see any bubbles, so I thought today I would have a look.
But I didn't know what I was supposed to see! ( this reflects my technical nous btw) :duh:
While the engine is off, the chamber is empty. When the engine and air-con are on, it briefly filled with what appeared to be a milky coloured fluid, then emptied again.
Is this normal? or is the air-con kaputt?
Can any of you technical gurus help me out?
Cheers,
