    confused Aircon light on when its not!

    when i started my Signum tonight to leave work i noticed that the light on the air con button was lit. Which was strange as i've not used it since buying the car in november. I pushed it to turn it off but no go. And i noticed the revs rise slightly as if i turned it on. I pushed it again, light still lit but revs drop back to normal idle speed as if it had turned off again. I turned ignition off and back on after a couple of mins but light came back on with ignition. Does any body have any ideas?

    Not entirely sure but, I would guess possibley that the air con switch is broken (the contacts within the switch which supply power to the LED) OR possibley a stuck relay. If its just started randomley (like you say youve not touched it since you bought it) then possibley a cable within the control panel. Not sure how "sealed up" those control panels are, dont know if you can service just the air con switch or if its an entire new panel needed.

    Bottom line, it it was me I would be checking any relays in the fuse box to do with air con, maybe remove and re-seat them to make sure they have a sound connection. If it is just the LED thats constantly on, then not a huge problem, especally if the air con still actually works

    Hope thats of 'some' use

    cheers pete. Tried all relays/fuses today and all ok but light still on. It did go off momentarilly as driving this morning but came back on again a short time after. I was wondering if it was a warning saying air con needs regasing, but looked through manual and nothing in there about it. Does any body else have any ideas?

    Is it lit, or lit only when the lights are on?
