I own a 1997 R50 SE with the AT that I've got a few problems/questions that I figured I'd come to the more knowledgeable for.
1. After using my AC, water drains onto the passenger side floor. I am aware that the drain is clogged, how do I go about fixing that? From what I've found, it's the black hose on the passenger side firewall, but when I felt inside of it I felt a plastic tube but it didn't have a hole in it. Surrounding said tube was foam.
2. Is there an easy way to changing the driver side, pre-cat, oxygen sensor? It's in a difficult spot under the break booster.
3. There's an electrical connector that's unplugged on the driver side of the engine bay that I'm unsure where and what it goes to. The wire is tied into the same connector that hooks up to the AC compressor. Here's a link to an imgur album with pictures of it, imgur(dot)com/gallery/snk7dZ6
Thanks for the help/advice in advance!
