    My 2002 Alero is doing the same thing. I start the car and the engine turns on, but the gauges and lights on the dashboard don't turn on. I got the backlights on the dashboard to come on by manually switching on the headlights, but the gauges still showed zero (driving 35mph it still read 0mph, tachometer at 0 while engine running, odometer LED display off, gas gauge showing completely empty, and temperature gauge at zero). Halfway down the road I heard a "click" (like a relay turning on) and all the gauges jumped to life. Maybe there's an electrical failure causing this.

    my 02 alero has the same problem. the dash board guages don't work and neither do the power windows or the airconditioner. After a few seconds (or sometimes minutes) they start working fine again.

2003 Oldsmobile Alero won't start

Chances are you got water inside the fuse box or a wiring harness connection.
You may have to start tracing circuits to find out what is getting power and what is not.

2004 olds alero 3400 eng.turn on key and all warning lights and gauges come up,then all goes off after 3 seconds,starter will not work,can start by jumping across starter and runs fine and shifts fine

Check for power at the switch wire when someone turns the key to start. I would say there is a break in the circuit of the thin wire between the starter & the ignition switch

2002 oldsmobile alero just died driving on the road

Turn the key forward and try to start the car. If it does not start, look for a light on the dash that says SECURITY. If you see that light, that is the problem.

If it does not start, leave the key forward 2 clicks for 10 minutes, NO LESS. Roll the key back for 5 seconds and then try to start it.

Im not sure if you got your alero to start yet. But heres an Idea, The alero comes with a security feature that if you have 3 failed starts it activates. a good sign of this is while having the key turned does your security light flash on the dash. if so turn the key forward with out starting the car and leave it on for 10 minutes and then the security light on the dash should stop flashing. Now turn the key off and remove key stick key backin and turn over to start car. Did your car start ??

I was having problems with the car not starting at times, turn the key and nothing would happen and the next time it would work fine. I replaced the ignition switch and now the car starts every time but...

Sounds like a poor electrical connection somewhere. See if there is a relay in the fuse panel associated with these functions. If so, you could replace that. Without schematics for the car it will be tough, but look for wiring that could be damaged or connectors that could be bumped in and around the dash area.
One tricky thing I have found is that sometime a poor or loose ground connection will cause problems like this. The wiring diagrams will identify these as well.

2003 alero dash light won't shut off

Sounds like either a bad ignition switch or a back feeding circuit. Try unplugging the ignition switch to see if the lights go out. If they do, replace the switch. If they don't, post to tell me.

If the security light is flashing when that happens, you need to turn the key to the ON position, and let it sit for 10 minutes, so it can reset the security code. Start it up as normal and let it idle for 5 minutes.
