Check fuse box locations. It will probably be labeled "horn" and most likely a 10a fuse.

What kind of noises you get and when ( when in drive, in neutral etc )?
The noises can come from a worn transmission bearing or transmission clutches.
The bad is that for either problem the transmission has to be taken down and/or rebuild.

Check for corrosion in the bulb socket or wiring connection points. This could cause a voltage drop, resulting in a dimmer light. If it looks good, then just replace the bulb with a new one. Use dielectric grease only in the bulb socket to prevent corrosion. Do not use regular grease because it will stop electricity from flowing.

The connector for the a/c refill is down below the alternator right behind the engine on the passenger side.

Assuming all work was done properly, check compression. It is likely you have low compression in one or more cylinders due to overheating.

I removed the top section of the fuse box on a 2007 Buick Terazza Van to get to the bolts to remove the entire box to replace battery; now everything is back together but having difficulty snapping the top of the fuse box to the bottom of the fuse box, is there a technique fo reinstall?

It should be in the main fuze box under the hood or in a separate box for relays.
Why do you ask? Have you got a startup problem?
When you crank, you should, or a helper, be able to hear the pump running under the gas tank. A high pitch whirring / buzzing. If you locate the relay you should be able to feel it click when someone cranks up. It may be fuzed separately so check that.

I have had issues with the security system being triggered which will put car in theft lock mode. Chances are that if you replace the ignition switch and key the problem will be fixed. Gurch.

One of many reasons, usually doing with the emission system. Most auto parts stores have a testing machine , that they will use for free, to decode the problem for you.

The drive cycle is a series of conditions that you drive a vehicle to prepare the emissions systems for an emmisions test.

the drive cycle that is most common to GM vehicles is the following;

1. cold start vehicle and allow to warm up to driving temperature, then set a load on the engine, ie. turn on radio and A/C MAX and headlights.
2. reverse vehicle for approx. 15-20 ft.
3. from a stop, drive vehicle at 35mph @ 25% throttle for 15min
4. allow vehicle to slow to a near stop without using hte brake pedal.
5, begin driving vehivle again 45mph @ 50% throttle for 15-20 min.
6. check for emissions status and test.

***OBDII vehicles (95-99) can have up to (2) two emissions monitors at unready status for PA and can sucessfully submit a "pass" status.
vehicles that are 1988 (OBDI) are emissions exempt.

New plug or new seal. Drain oil first. Can get messy if you forget that. Red.
