Thread: Right hand aircon vent not as cold.

I have same problem. Did replacing the part work? I fiddled around with the arm at back and oiled the cable. It all seems to be sliding nicely. So next move would be to replace that white plastic thing.... interested to know if it solved your problem before I do so

Me too. I'll let you know after I do it.
After I oiled the lever, moving the lever over manually has taken it further than the cable from the dial took it, and made it acceptably cool, so it's a temporary fix, but I'd like to get it even colder.
In my case the air-con has just been serviced, so I know it can make lots of very cool air, so that rules that out.

It worked for me, stopped all the hot air coming in, but I don't get any cold air from the aircon, but after 9 yrs it probably needs re-gassed. But it definitely stopped hot air coming into the cab.

Pop the cable sheath out of its holder (black metal clip) on the tap assembly, pull it out a little further (to the passenger side) and pop it back in. Test with the dial and repeat till the dial pushes the tap all the way home.
Then test drive and see what happens.

Thanks. I checked and the arm was already over as far as it would go.
Anyway, today the new valve was fitted during a routine service.
It's too early yet to say if the air-con will start to warm up after a drive of longer than 15 mins. Ill report back.
One interesting thing noticed was that there was quite a lot of crud inside the heater valve, which may have been preventing it closing.
So, in hindsight, I would disconnect the hosts and clean out the pipes inside the valve. It might be cheaper than replacing it.
Also, make sure the arm is well oiled so it will slide over easily when pushed by the cable.
The things we learn...

So here is the new valve fitted.

First result from fitting the valve was disappointing, as the air-con still warmed up after 15 mins of driving, as the coolant circulating through the hoses got hotter.
Feeling frustrated I took it back to The Workshop (formerly ABS) in Moss Street at Slack's Creek, thinking maybe they might have to install a stopcock to turn off the hot water flow so the air-con could work properly. This is Qld, so we need air-con, but not a heater.
Instead the owner Michael got one of his lads to make some adjustments. I've just been for a 30 minute drive and I'm delighted to say the air-con stayed cold.
I'm not sure exactly how he adjusted it, but it's obviously important to properly set it up.
So, hope that helps.

That is great!
I got mine re-gassed today and hooray, I have aircon back and nice cold air. I will still go and oil the cable on the new valve as I think it sticks, I have to turn it from cold to hot to cold a few times before all the hot stops. The new valve has defintley fixed the hot air coming in so well worth the effort.
Would be interesting to see what fine tuning they did on yours, maybe the cable adjustment or something.
