I've got a slew of questions that would help me out a lot in fixing my girlfriends 92 LX. I'm not too keen on engines, do alot of body work, and now that my cars ready for some engine work, I figure learning on hers is safest

.
1. Her car is an automatic, just like mine is (for now

) - When her car is in park, I can hear a clicking noise everytime I hit the brakes. But if it's in any other gear, there isn't a clicking noise. I don't know if this is even an issue that I should be concerned with, but my car doesn't do it so I figured I would ask.
2. I found out from another post we need a VSS for it, but I was curious if any Honda VSS will work for it, will just one from that generation work, or just from that year (92).
3. The automatic door lock and the passenger window button on the drivers side don't work, and I'm assuming that it's just the fuse, but I figured I'd like to know if there's any other options it could be so that I can troubleshoot it.
4. There is one of the A/C vents that doesn't shoot out air, is there a line that could just be backed up, or do you know of anything else it could be (all the others work fine)?
5. The frame (according to the dealer) isn't bent, carfax didn't show any accidents, and I am positive the tires are balanced, but when doing 50+mph, there drivers front tire feels like it pulls a little to the left. Any suggestions?
I greatly appreciate everyones help, and I hope that teaching me even these simplest of tasks will hopefully help other noobs at some point as well
Thanks again in advance.
