Water and electrics are never a good mix Quote Link to comment Share on other sites More sharing options...
NathanR Posted September 13, 2021 Share Posted September 13, 2021 Late to the party but wd40 is water displacement 40th edition and not the pen oil many think it is. A liberal spray will get electronics out of many damp/wet issues Quote Link to comment Share on other sites More sharing options...
Shytot Posted September 14, 2021 Share Posted September 14, 2021 If the fuse box is at either end of your dashboard or under the glove box, a likely cause of the water is leaves in the bulkhead stopping it from draining. If you open the bonnet you should be able to remove the plastic covers and clean the drainage area out. You should also have grommets underneath which you can remove and poke from the bottom. The other common issue is if you have a a sunroof and the drain is blocked. Fingers crossed it's just a blown fuse 👍 Quote Link to comment Share on other sites More sharing options...
