"R" reg Astra. The heater fan control knob "clicked" internally the other week, and now it seems to have no effect on re-directing the flow of air.
I am a Proud Veteran of changing the bulbs behind the heater controls (but see below). Took me over an hour (*with* advice from this group) to get at the bulbs, but I bet I can disassemble the console in 10 minutes now.
However having got to the heater control panel behind the console, and located where the bulbs are, the components are so extremely tightly packed that ...
(a) I COULD NOT find the third bulb which I know must be there (the one that lights the rear demister indicator when you pull out the central knob) and
(b) I COULD NOT work out what I should do to repair/replace the fan control knob. I could see that it's a sort of cam on the knob which fits into a variable channel, which controls a cable ... but it's all so tightly packed that I didn't want to bust it further.
What's your advice chaps? Replace the whole knob and assembly (perhaps go to a scrappy)? Or deliver it up unto the Vauxhall dealers?
I'm tempted to just write it off as U/S - I do get air blown out, though it's fairly undirectional. It seems dreadfully complicated and tight in there, and Confucius he say: a console is a thing of many parts: as he who disassembles it is doomed to find out.
