Door locks stopped working?

Within the past month:
-beep beep beep sounded from either the driver's door or driver's side fuse box
-drivers side electrical door lock failed
-heat goes on and off but no changes to heat settings
-various dash lights have gone out

could there be a central, single problem? All fuses look good.

This site is more helpful every time I log on. So many people with the same kinds of problems. I too, own a 2002 Chevy Malibu 6Cyl 2WD Automatic 150,000Miles.

-How do I check/change my car horn?
-What would cause my dash light's to go out?

I have a 2003 and a 2001 Malibu. When I put the 2003 in drive or neutral or reverse the doors automatically lock. And in park they automatically unlock. On the 2001 it does not do this. I have to lock the doors manually. Is there a way I can turn this feature on on my 2001? The 2001 is an LS the 2003 is a base model.

How do I know which mode I am in?

Ok so one chime equals mode 1. Thanks a lot.

I can unlock all four doors and when I put the car in drive, neutral, or reverse they will all lock. But the switch to the inside of the car won't lock or unlock them. Neither does my control, my remote won't lock the doors. I don't think that it is the original lock for the vehicle so I have no idea if the previous owner did something wrong. My remote and door switch won't lock or unlock the doors. But if I unlock the doors manually and put the car in drive they will all lock. What could the problem be?

No even from the passenger side switch the doors will not lock or unlock with it. The only time it locks is when the car is put in drive. I have a baby on the way and don't need to be fumbling with the locks you know lol. Um what is the bcm? But the doors won't lock or unlock with the switchs on either side or the remote and never have. What do you think that this could mean?
Thank you very much

Oh one other thing, does the middle console where the shifter is, is there a light or fuse that lights up the PRND12 gear symbols?
Thank you again

Thank you so much for your help regarding this. So if I go to a chevy dealer and say "I need to have it scanned for trouble codes" they will know what I'm referring to? Or would they need to be caught up on the whole story?

My car makes a relay grind when trying to unlock it and when at drivers door it opens all four with a grind. Wont re-lock unless you do it manually. All other relays truck etc work. This car was bought used and the drivers door was shorted and glass was down. I replaced the panel containing window switches and now they work fine but not the locks. If you accidentally hit the unlock switch its got that relay hums loud and it opens all four. Guess it is not a fuse it sounds like a relay, but where is it and why all four doors?

On my Malibu, my 1 and 2 for a/c and heater control button won't work. It turns but it won't blow at those intervals. Why won't it work for those? Oh and thank you for the light bulb thing, thats so much better.
Thank you

Way off base but thanks. The grind comes from all doors. Windows go up and down lock by key or manually flicking the tab on the door. Opens and grinds when any of the equipped doors are pushed upwards and the grind is in the dash. Must be a relay that is bad on one end. It just echoes in the doors. Unlocks but wont lock. Where is the relay that controls the locks?
