Touchy Air Conditioning/heater Trouble

[thats4shaw]

Hi all,

Done a lot of googling on this issue, a lot of topics and not too many solutions so this is my last attempt before I cave in to take in to a shop.

My air conditioning unit either blows full cold or full hot. Setting the temperature to the coldest blows cold air as it should, but putting it up two notces gives me hot air as if I had to put it the warmest setting.

I have checked to see if the room sensor under the steering wheel was sitting in it's correct place and that that the solar sensor by the windshield was plugged in and both we all good. From what I can tell all the servo motors are functioning as normal, is their anything else I have missed by chance and anything I can check before I open my wallet?

Cheers fellas

It will tend to do that in "Auto" until the cabin temperature reaches the set value, when it should settle down. The blower fan then slows and the servos then control the mixture of hot and cold to maintain it - with the A/C pump switching on & off as required.

Thanks for your reply :-).

The trouble is I don't have set it to auto. In reality I only have two heat settings when adjusting the temperature knob - extremely hot or extremely cold.

It only controls to the set temperature in Auto.
