Guys, I currently have no ice-cold aircon. When I turn on the aircon, the button lights up, but temperature of air from vents does not change at all. All other heating/ventilation controls and adjustment appears to work exactly as it should with no erratic fan speed or other problems normally associated with final stage resistor unit. Am I correct in assuming that this is unlikely to be a final stage resistor problem, or could a problem here present itself only with lack of aircon, but all other heating controls working perfectly.
The auxilliary fan does not come on when aircon is switched on, but I know it does work as a) I have replaced this (due to unrelated cooling problem issues), and b) I have heard and seen this fan operating.
I have had aircon topped up last summer, although if I have a leak, I am sure this would need redone.
I would like to look at this, at least initially, from a DIY point of view. My first inclination is to buy a regassing canister of R134a refrigerant and top-up. My question is, based on what I have said, is this likely to be the problem. I mean, if there is insufficient gas in aircon system, would this cause auxilliary fan not to come on when switching aircon on. Obviously I could be looking at other specific aircon components which would be beyond my ability, but don't want to hand over to specialist if this could be a relatively simple repair.
Any advice appreciated.
