Interior Lights Wont Turn Off ?

[DaveSr]

Hi I own an 1998 Chevy Blazer 4x4 which I purchased used last Winter
the truck is very nice, rides nice handles nice and works great in the bush
to get me back to the fishing spots. This is the first GM ive ever owned and
persionally I really like it but unfortunally like anyone else when purchaseing an used vehicle you can expect to have parts wear.

Heres what ive replaced in the last year since purchaseing it.

Front Rotors and Pads
Rear Rotors and pads and 2 calipers.
Battery
Fan Blade.

Now here are another few problems I am haveing and Hopefully someone can help me out here.

problem # 1

Interior lights will NOT go out on there own only after being on for 20 minutes will they automatically shut down by computer.

currently ive got them in override mode so they never come on

how can i fix this? anyone else had this problem before and what was the fix?

Next problem

from a complete stop to driveing up to any speed there is a loud humming noise comeing from left front wheel area

Possibly weehl bearings ??? any ideas what else could be causeing this?

last but not least

The button to open the rear hatch no longer works when its pushed the only way to open the back hatch is via button inside the cab or with a key.

Sorry about all the complaints they arnt really a big deal i just like to keep on top of things and get them fixed ( myself ) if i can just because i like everything working properly
anyhow great message board guys keep up the good work hopefully someone can chime in on some of the problems i am haveing
