Title: aircon/heater
Post by toppin2 on Jul 5^th, 2007, 5:59pm

when driving on a short journey the ac and heater work fine, but i noticed the other day that on a long motorway journey after a while the air seems to stop blowing but yet you can still hear the heater fan working, its like its gradually fads away, switch it from auto to max and the fan is going, but little air. i switch off the air con all together for around 20mins and it works fine again. any ideas?? cheers, Dave.

Hi,

thats normal, i think. the aircon is actually climate control, it measures the internal temp and "adjusts" it using the blower. as it approaches the selected temp, it slows.... finally stops, with just an occassional blast to adjust. when you turn off the ac, the temp will rise again, so turn it back on, blower will blow until back to temp

hth,

it could be frezzing up. after a longer drive with the a/c on. take the polen filters out and see if the evaporator has ice on it.

yes, this sounds like what the problem is, as its a gradule decrease,and it should blast out if switched from auto on to max. any ideas y it would freeze up? i have only jst had it regassed a few week ago, as it has never worked since i got the car. cheers, Dave.
