Thanks for the help! I did the battery thing, and that didn't help. Right now they're changing a part that is involved with the computer. I forget what it is, but I know that it is a roughly $500 part. The hard part was getting it to happen while it was in the shop. The BCM shouldn't have been it (according to the shop) because my door locks, windows, lights, or any of the other electrical body components weren't acting up. My dashboard, and the engine were all that seemed affected. I am getting the car back tomorrow, and I will post what part we replaced, and whether or not it fixes the problem. I hope it works, but I'm pretty realistic about electrical problems. It can take time to find the real culprit.

So I just got my car back yesterday. I had the ECM changed. It's a $500 part of my computer that (I guess) tells my car what to do and in what order to drive down the road. I drove around for a few hours after picking it up, put almost 150 miles on just trying to shut it off. So far so good. Not one hiccup. If anything changes, I will post what happens and what we do to fix it. Money is no object on this one, because the car only had 33,000 miles on it when I got it (I know, pretty good for a 2003) so our bank offered an awesome warranty that I will be availing myself of any service I need to to figure this issue out.

Easy fix bro. take apart your key fob and carefully bend the battery contacts out slightly and swap the 2023 remote battery for a 2032 remote battery. perfect fix will never fail again. i had the same issue.
#430 of 433 Daytime Running Light circuit goes crazy
Dec 10, 2012 (2:12 pm)
I have an 01 Impala purchased new. I have been very pleased...good economy, comfortable, great looks. Recently I have encountered a problem connected with the Daytime Running Lights. When driving daytime with the DRL "on", the entire lighting system, including dashboard lamps will go into rapid oscillation with accompanying noise like the clicking of a relay from the area behind the dash on the passenger side. This occurs when the car passes into shadow, such as that of an underpass. I can simulate same by putting my hand over the photodiode on the dash. There is supposed to be a time delay built into the system so that short passages into darkness do not produce such an effect. Oh yes, if I pull out the headlight switch, the relay noise persists but the lights no longer flash off and on. Driving at night there is no problem. Anyone have this problem or heard about it?

Sounds like the symptoms of a faulty BCM (Body Control Module)
Your best bet is to have the dealer diagnose this. If the BCM needs replacement you are probably looking at $500-600 dollars. Unfortunately you can not replace this yourself because it requires special programing that involves a computer and typing in your VIN #.
Good luck! Other common problems for this model vehicle is defective high/low beam combination switch. Faulty Passlock sensors, Noisey ISS shaft in steering columnn, intake manifold gasket leaks, and recall on cat converter. Other than that it is a smooth riding car!
#432 of 433 2003 Impala Power to Heater Blower, Cruise Control, and Info Center
Dec 31, 2012 (3:18 pm)
I am trying to troubleshoot why my heater blower, cruise control and info center above my rear-view mirror has stopped working. I am trying to confirm power to an orange wire next to the driver-side fuse box. I have confirmed no power at the fuses. I am hoping the problem is the wire box below the fuse box and not the ignition switch. I have a wiring diagram and the power feed to these three fuses is via an Orange wire. There are two Orange wires in the box, I am trying to determine which one feeds the fuses for these three devices. I have a picture of the fuse box. Any help is appreciated.
