Sometimes when battery voltage is lost, some modules may have to be reprogrammed or relearn? Do you have a security system?
You could always check the basics, have a helper crank it while you check for spark at the plugs. Also, check proper fuel pressure and fuel injector pulse. Let us know what you find?

If you turn on your AC on one day and nothing happens, you may be dealing with a major component failure. Your vehicle's AC system consists of a compressor, condenser, evaporator, expansion valve, a series of tubes and several fans/blowers. If either one of these components fails to do their job, it may result an entire system failure. For example, if the evaporator blower motor burns out, you will get little to no airflow through the vents.
Most modern vehicles also have safety mechanisms that may prevent a component from engaging if the pressure is low in the system due to a refrigerant leak. Refrigerant can leak for many reasons, including undone welds, loose connections, corrosion, physical damage from road debris, etc. Look for oily stains underneath your car, as they may indicate a leak. If you suspect a refrigerant leak, take your car to General Automotive. We will test the pressure and use special dyes to pinpoint the leak.
Warm Air is Coming Out Instead of Cold As you get in your car and turn on your AC, you probably expect it to be blowing hot air for the first minute or two until the system cycles through enough to cool it. But what if the air never gets cold ? Or maybe it it gets cooler, but not cold enough ? No, your car didn't get confused and turned on heat by accident. There is likely a problem with your condenser.
A condenser's job in a vehicle is to cool the warm refrigerant that was used to make the air cold in the evaporator. A condenser has coils and a fan to push the air through the coils and thus cool the refrigerant. If the condenser coils get dirty or clogged, or if the fan fails, the refrigerant won't be cooled completely, so the air will come out warm. It's best to take your vehicle to an experienced AC Repair professional to troubleshoot this problem if you don't know your way around under the hood.
Cold Air Blows Intermittently So you went for a road trip or a long drive, and after 30 minutes of driving realized that your AC suddenly stopped working or switched to blowing warm air. The cold air returns shortly, and the cycle repeats itself for as long as you are driving. What's wrong with your car?
Intermittent cooling is often caused by the components of your vehicle's AC system freezing up. Typically an iced over evaporator is the culprit. An evaporator covered in ice can't cool the air, so you would have to wait until the ice melts, which is why the cold air eventually returns. There may be numerous issues causing the icing-from a dirty cabin air filter to a blocked evaporator drain or an overcharged system. Look for puddles of water under your car-this could be a sign of a freezing problem.

Define the issue a bit Further. does check engine light flash while stopped? check the basics is there air restriction and when where plugs last changed?

In order to answer your question, I went to "e-bay" and looked up instrument clusters for your vehicle.
As I suspected, the bulbs are "peanut" bulbs, and they press into a small plastic socket, that twists off and back on the rear of the instrument cluster panel.
I don't think you will be able to change that bulb without removing the whole instrument panel cluster from the dash.
I might be wrong.
Look up under the dashboard and see if the back of the cluster is easy for you to see and get your hand up to.
If so, good.
God bless your efforts.

So your saying you have problem with power door locks? Or when you try to open door, the window is hung-up? Can you explain?

You may have to turn on the key to get power windows to work.

As you can see, the power window circuit breaker won't get any voltage unless the key is on.

check fuse, then run a ground wire to the wiper motor and ensure the ground is good. if the wipers start to work then the motor just needs a permanent ground connected to it. if it doesn`t work then check for power at the motor if you have power then tap the motor with a hammer to see if it starts if so then the motor is bad.

The back latch is electric release. It's a fuse under the dash. I forget which one, but it's not the door lock fuse. Just pull everyone and you'll find it.

It could be a faulty relay. It should be marked.

No fuse, but if you have daytime running lights and are experiencing headlight trouble, that circuit could be the source of the problem. Also, in the 1999 model year headlights could be either composite or sealed beam.
