how can I fix water leak?

Hi. I have the same problem, but I'm sure its the windscreen washer pipes that are leaking because it smells like that, and my washer bottle is now empty - so no more leak. I'll fix it when I can work out the pipe runs.
If it was your ac condenser the water wouldn't amount to as much as you describe. Suggest you have a look at the following website which describes the fix for the condense and is packed full of good advice http://www.rangerovers.net/newrremedies.htm#intro
Best of luck
