Thread: Baked the wife today in the 130

Does your heater control knob operate fully across from hot to cold? The cable that goes to the heater control valve was knocked off by the dealer and put back incorrectly, so I had hot air coming out, very simple to adjust it just pushed in, but make sure you position the cable right. It sounds like hot water is getting into your heater core, so I think it sounds like your heater control valve is not closing properly.

I had a look at that the other day, as mentioned the cable pushes the heater tap shut rather than pulling it shut as is the case on every other heater tap I've known. Being a flexible cable, i.e. multi-strand core, it does not 'push' very effectively. Perhaps there should be a spring arrangement to assist the tap to shut fully? The standard way of adjusting heater taps in my experience is to make sure they are fully closed when the control is on 'cold', as it doesn't matter if they don't quite open all the way when hot is selected. The adjustment seems okay, but the flexible cable just bends instead of pushing the tap all the way shut.
I've pushed the heater tap shut by hand and there seems to be an improvement in the a/c performance but still not great, cold shoulder is definitely not an issue (not in this context, anyway!). When fiddling with this with the motor hot the other night I also discovered the source of a coolant loss- the heater tap is leaking, guess I'm up for a new one. Another item for the service agent next week, along with an aircon recharge.

Just to make you feel a bit better.

I drive a 150 Prado for work.

Yesterday the temps outside were 47°c and the a/c on high couldn't keep up.

Sweated my butt off for 6 hours driving.

Obviously the result of poor LR build quality....

Well the D4 drops car temp in minutes and then stays nice and cool..

The Prados on the fleet ALL suffer the same problem.

BLACK BLACK SVX...... and glass sunroof. A/C absolutely excellent at 36-38 OAT.

Would also like those centre vents to be adjustable.

Only complaint is that with "fresh" air it gets heated in the mudguard and the engine bay ducting. Need to insulate the tract till it gets to the firewall.

Drove around all day today in 35* heat with the drivers window down and the windscreen vents wide open and was comfortable.

Oh that's right, I have a Tdi

Have cooked the wifes legs several times in the TD5.
Love the response when I tell her "to harden up princess!"
Personally, most of the time I prefer the vents & window option.
At 60kph+ those front vents work bloody well..........
