Hi, the air con isn't working. When I press the a/c button it lights up but the air con doesn't kick in. Is there a fuse or relay to check first? and if so where are they located. The air con compressor obviously doesn't turn by the belt when the light for the air con comes on. Went to a garage where they regas but they said the air con wasn't working so they couldn't regas. Not sure what to do as I don't want to pay renault loads of cash to check it out. Any ideas would be great! !
