My day time lights are not coming on anymore, but my headlights work normally. which fuse am I looking for?

SOURCE: Assumed blown fuses - looking for fuse panel on 2003 Chevy Impala

I don't know about the rear defrost, but there are 2 fuse boxes inside the car. Just inside the doors on the far sides of the dash. The covers sit between the dash and the doors. There are holes to stick your fingers in, and pull the covers off.

The fan issue, may be different then the prob. I had, I didn't have speed 1 or 2 on mine.
I don't remeber what the part is called, but it's some resistor board deal, that sits up under the dash on the Pass. side, right up against the firewall, it's a pain to get the new one in, once the old one is out though, so be careful not to crack the board. Ask a dealer, they will know what it is. I think it costed me like $30.
I hope that helps.

there's a button on the right side of the steering wheel that says serv push that button. It's put right there for when they use them as police cars you can cut the headlights off. You will probably notice that dash lights are on.

With electrical problems I always look for a bad ground wire, especially on older vehicles. Look for any wire that goes to an inner fender or the engine, there maybe a faulty relay in the circuit too. good luck, Chuck

Was sent in by another poster, just posting his results which fixed mine. Problem was relay $50.00 at GM only.

Check the relay module. 45 or 46. on the engine relay block. you can swap the two they are the same part number, then you will know. Dont start the engine, just check the lights. If it works replace the relay module. You may have to order the part from the parts store. Or go to the dealer to get it.

Start by setting your auto headlight switch to off if this solves it replace your headlight switch If your car is equipped with daytime running lights there could be a short bridging them with your auto head lights look for broken or frayed wires do this also if you have installed or had someone install an aftermarket stereo or speakers/sub woofer, amplifier. Good Luck with this
