Air Conditioner

Ok i have a problem

Aircon doesnt want to engage.
light works when i press the switch i checked the relay thats fine.
where should i start. i dont here a click when i switch the aircon on and i can see its not engaging under the bonnet i think its the compressor but im not sure what its called the thing that has the belt running to it. doesnt engage at all but when i press the aircon button the revs drop a little and then go back up.

Not to sure really need some help othgerwise its off to the Auto Elec.

If your gas is low (the car, not you ) the low pressure (?) switch will detect the excessively low pressure and prevent the compressor from engaging. To check for low gas, look in the sight glass of the receiver dryer. If it's clear and bright BAD, if it's straw coloured GOOD - but you still need a look see by a tech.

have alook at all the conections of the A/C lines and if they are covered in oilly dirt the o rings need to be replaced. Dont try to do this unless you know there is no gas in the system. Take it to a A/C place. If the car still has the ac gas R12 in it you'll have to replace all the o rings and the reciever dryer as you cant get that gas anymore. There should be a sticker on the radiator support panel which tells you which gas it has so the A/C place doesn't try and rip you off for the new gas.
