What fuse or relay do I check to run my air conditioner?

Need to know first if the condensor fan comes on (even if the compressor doesn't kick on) when you switch the A/C on inside.If the fan doesn't come on then the problem might be pcm or control switch. Assuming that when you jump the clutch it blows COLD (not just a little cooler) air. Also , if check engine light is on , there are certain engine conditions that will cause it not to allow the clutch to kick in.The relay is in the underhood fusebox. Flip the lid for diagram , relay will be the one with a picture of 'snowflake and clutch'.

You should first try to turn it on and see if it works.http://www.lightdeal.co.uk/
