R33 Climate Control Issue

[Mick_o]

Hi guys trawled the D.I.Y sections and havent had any joy finding any info on my issue

Basically my air con is cold 95% of the time but occasionally just stops going cold and its a PITA.

So ive done the self diagnosis with the climate control and the code 25 has come up which is the sunload sensor near the windscreen apparently

Just wondering if its a big job replacing it and where a new 1 can be purchased?

Id appreciate if any of you fine gentlemen in here can give me some advice on how to replace it or reccommend somebody in sydney who knows there shyte

Cheers

Mick

I hope you didnt do the test while inside a garage or under shade, that will trigger the sunload sensor warning.

Yes make sure you didnt do this lol

But if you need to replace it, you pop the LHS demister vent (or maybe its the right you can kinda see it anyway) out and unplug the sensor. Not sure where to go from there but should be easy enough with that out of the car and in front of you

The sensor is definetly part of one of the clip in vents that sits in the front of your main dash just before the bottom of the windscreen

Oh dear i done the test at night after reading bout it lol would that really affect the test result??

Sunlight sensor detects sunlight........ No sunlight = sensor gets no reading

Ok well thats gay just done the check in the sun and 20 came up which means everything is ok so WTF does my air go warm randomly from time to time

Most likely the servo door actuator, very common problem where the cold solder joints in the plug crack from old age/vibration. It will sit there not receiving power on the last selected setting, sometimes a bump in the road etc might momentarily complete the electrical connection and the door will change position.

Behind the radio, that area. there will be a white rod attached to the servo door actuator (which lets cold or hot air depending on position), best to find it from the passenger side.

There's a guide for it in the diy section. something about the air blend actuated or door

There is a temperature sensor and hose connected to the dash. Sometimes when I remove the dash, I forget to re-install those two and I don't get cool ac.
