New owner problems: Interior lights, Leaky trunk

[ebmcphers]

I have a 1986.5 Supra, 7MGE. As several other people on this forum, my dome light did not work when I bought my car. I searched the forums and found a fix (rivets loose). The lights now work then I push the buttons, but not when I open the doors. Also, strangely, the light around the ignition and bellow the steering wheel used to work when the door opened and after I "fixed" the dome light they no longer turn on. The little red lights on the doors still turn on however. Any suggestions?

Also, when it rains the wheel well for the spare tire fills with water. I checked the weather stripping around the lift back is good. Any places these cars regularly leak?

Any advice on maintenance or good modification I should do? The car has 150k miles. The head gasket, I believe, is good. I've already cleaned the air filter (k&N), and throttle body. Replaced the spark plugs, fixed the leaky oil plugs (throw away the #3 cylinder gasket and used RTV) and the timing belt.

Thanks a lot.
