Huh?
If the car is at 31 degrees then that is right. Can you give more information? How long were you driving, what was the outside temperature, was the car cold inside, was it day/night etc.
I assume you have checked the coolant level?
hi Nick, drove about 8 hours and temp outside about 10-15 degrees (left Auckland about 11-30am and home in wellington at 7pm for dinner).
coolant in radiator bottle all good.
could it be a blockage in the heating hoses?
I've noticed on longer journeys that the air from the vents gets cooler and I have to turn up the temp to keep the car warm. I think that there is an internal temp sensor on the climate control unit that warms up with the lights etc. There is a hose that attaches at the back of the temperature knob that I assume is there to try and keep everything under control. Certainly the issue seems worse if that tube is not attached. I have considered wiring in a small fan to move the air through that tube to see if the cabin temperature is better controlled on long journeys.
Certainly first I would check if the car is behaving normally now everything has cooled down and I would be checking the tube on the back of the climate control unit.
In addition to what Nick says, I think it is worse if you have an aftermarket stereo. The extra heat from the non-standard stereo also causes the internal temperature sensor in the climate control module to read higher than usual.
Some BMWs have a similar issue - they placed the temperature sensor above the cup holder - so if you put a hot drink in there, the temperature drops, and if you put a cold drink there, the temperature increases!
You need to swap the tray with the stereo, so that instead of this:
A/C ECU
Stereo
Tray
you have this
A/C ECU
Tray
Stereo
I had the exact same issue (cold air out of vents when I wanted it warmer in the car) in my V6 N/A Galant, and the swap solves it. Also did the same swap on the Legnum.
Interesting, I have mine A/C, Stereo, Tray with no issues (so far...). I had one issue in the previous galant where a plug under the glovebox had burnt out but that was giving me constant heat.Quote:

This is where the AC unit gets its internal temperature reading from and if it is disconnected, you can get the problems you have described.
thanks Kenneth (and everyone else) for your input to this problem, l will check it out when time is available before the next cold long drive :)Quote:
