Hi all laguna owners does anyone have this intermittent fault. Whenever we seem to have a damp night and I get in and start my car the auxhillary belt drives me up the wall it squeaks not very loud like a fan belt would but enough to annoy me. When it first happened I was told by 2 mechanics it needs a new belt and another told me it was mechanical. When the weather is good you would never think there is any thing wrong. someone suggested putting baby powder on the belt or pulley any suggestions please.
