Well the recharge has improved things, but there is still some very strange behaviour: 1. In the Winter the fan doesn't start blowing until you have driven a mile or two. i.e. until the engine has warmed up a bit. This is expected behaviour. However, it's the same now??? i.e the air con does not kick in until I have driven a couple of miles, when it should start as soon as you turn the key. 2. When it's really hot (say above 33 degrees), instead of the fan blowing at full speed continuously until the interior temperature drops, it goes through a constant cycle of speeding up and slowing down again. Very weird! Oh, and fan speed still increase when you engage reverse gear! Does anyone have an explanation for these odd goings on?
