Thread: Rogue Driver's Aircon

Looking for some advice on what/how to fix my wagon.

The driver's compartment aircon has begun blowing warm-hot air after an hour or two of operation, regardless of the setting. The other compartments work fine. If I adjust the intensity setting to max (three blue dots), cold air returns to the drivers side for another hour or two, but at the expense of freezing the passengers. Leaving the car off for several hours, seems to reset the system.

Needless to say, this was the opposite of awesome when touring on the hotter days lately...

Any thoughts??

Cheers,

Mine has iced up. Turn the AC compressor off (snow flake button) - leave the blower going for a while (5min tops, it will clear faster with the blower than turning the whole system off) - press auto (or snow flake again), and all is good.

Give away for me was the first time it happened I was nearly home, parked in the garage and 40min/1hr later noticed an unbelievable amount of water on the floor, checked and it all came out the AC drain. Started it up and all was good, came to the conclusion the evaporator had to be iced over to hold that much water and let it go that long after the car stopped - there was no puddle on the drive where it sat while I opened the door. The evaporator is so cold condensation turns to ice and once it starts it just closes over the evaporator fins – thermostat thinks it is warm, and tries to cool the evap even further.

Not sure if it contributed to, or caused the issue but my system was getting low on gas, took it in for an AC Service before xmas and it was low, topped up, no issue since. Most times it happened were in the months prior to gas topup and it was more frequent just before. Not sure but maybe lack of gas doesn’t allow full operation of all evaporators to satisfy the ECU, and one/two end up running colder than norm (icing over) or it could be coincidence…

Going through the records the previous owner provided (which are absurdly detailed), the gas was topped up at 4yrs, took another 4yrs to drop – looks like I have a 4yr leak – bugger.
