I was driving my Astra back from the Central Coast to Sydney yesterday with the
fan and cold both on full (I'd been walking in Bouddi NP and the car had gotten
hot parked) when after a while I noticed that it wasn't cold anymore. I've now
checked it again this morning and it's still not working. I checked all the
relevant fuses, and yes, I did actually have the air conditioning switch on (it
lighted up okay). What else could have gone wrong please ?
