Thanks for replying. I have managed to stop the water leak coming in, the windscreen scuttle was cracked and it was causing water to run off into the pollen filter itself. I have dried everything out, replaced the filter and housing with a new seal, now it’s just getting to the bottom of the drain.. I got the ccm out and opened it and water come gushing out I have dried all the carpet and the module out and cleaned up the corroded plugs as there was one or 2 that didn’t look good, however the circuit bored looked in good nick. I have had the battery on charge all day ready to put on the car this evening to see if it is still draining over night.. I’m hoping the drain was caused by the water and corrosion, I plugged the hazard fuse back in when I dried it all and they are now functioning properly and not stuck on so I’m praying to god the battery holds charge over night as the drain only came when the water damage got bad. if not I’m completely out of ideas
