Is my air con working?

Post by No-One » 11 Nov 2001, 19:33

I bought a 1999 306 LX yesterday. As I understand, when I press the A/C button, I should be able to hear a change in engine revs. However, I don't hear a thing and the rev counter stays put. Is it just not engaging because it's cold outside? I need to check that it's working properly before the warranty runs out in 3 months time.

Hi
A couple of things to try. When you switch the air con on, do you hear a relay-type click from under the bonnet as the elctromagnetic clutch engages on the aircon pump?
Secondly, do the ordinary rdiator fan(s) come on when you press the switch?
Also, a bit vague in this cold weather, but drive around with the heater full on and really warm up the car. Put the aircon on and set temperature to cold. Does the air coming in feel REALLY cold?
Finally, in weather that's even just a little bit humid, if the aircon is working, you should see water dripping off the heat exchanger under the car. Leave it running for five minutes with the aircon on, then move the car a few feet. Look for a trail of water drips underneath. A change from level to sloping ground helps the drips fall off!
Best of luck.

1. Should I hear this click as soon as I press the button, or is there a delay as the system detects the internal tempature?
2. When I have the A/C on for a few seconds, I can hear another fan like sound the sounds like it's behind the passenger footwell. Is this A/C or the recirculation function?
As for feeling the temperature, I'll try it when I get the oportunity.

1) The click is pretty instant on both my old BX and my current Xantia. It's pretty loud if you have the bonnet open and get someone else to press the button.
2) Not sure what that noise is on your car on your car. Both my BX and the Xantia have two radiator cooling fans. They run when you switch the air-con on Also cars at work do he same. I'm fairly sure your car will too.

Well then, mine's definitely not working. I can get a gas refill done for £25. (Cash in hand)
