Climate control 'auto'

[A L 3 X]

My 98 Glanza has the climate control heater controls, now whenever I put the fan speed to auto it always seems to be at mid speed, surely that isn't auto? Any idea what's wrong?

Mine didn't come on for ages the other night when I put it on auto. some times it's full when it's on auto some times is slow very strange.

When on auto it only operates the fan when it needs to, say u have it set to 20, it'll heat the car until it gets there and then run the fan slowly to keep it at that temp! If u then put it say down to 16 normally if u have it, it'll kick the aircon in and lower the temp down to that level and then slow the fan off to keep it there

Mine doesn't seem to do this, granted ive only tried it on the hottest temp(is that why) but all it seems to do is maintain the fan speed at mid :/

ahh really, sounds like the temp sensor is naf, when u get in your car today set it to auto and then adjust the temp and see if you can almost stop the fan.

This should be your inside air temp . then go lower maybe see if it kicks in then? it should go full speed on max or min I know that

I won't be using the car in this weather but I'll get in it and have a mess about, any ideas where the temp sensor is located?

I've just started the car from cold, the heater was set to max heat, I put the blower to auto and it seemed full mid speed, I put the temp to cold, the motor went to low for a second then to max it sounded like, so there is some alteration when it's on auto is this right?

[MARC MOSS]

yep, cause as you go from hot to cold it crosses the actual temp inside the car which slows it down

Ah cool, cheers mate, been testing this out and it does indeed all work
