Does anyone have a layout for the relays in a 2003 Grand Am? The layout in the user's manual doesn't seem to be correct,and I am having problems with the dash lights and gages, fan, and power windows/locks not working when the car is started. I replaced a relay and that seemed to work for a week or so, but the manual says it is for the horn (?).

The horn is fused and will be listed in the fuse box layout within your user manual.

Maybe your indicator relay.
I'd check on your car users manual for fuse and relay layout and check to see if the fault is there.
Hope that helps

I got a link that might be helpful. Hoe that his helps, since it says that this layout is for '99 Jettas and newer models.

there is a body control module behind the fuse box under the dash. it runs the wioers ,widows ,and locks,and much more

should be a switch on the back doors to turn on and off the child safety locks it requires your key or a flat blade screw driver.. let me know if this works for you

Wish I had like an owners manual that just give a layout and what the fuse is for. I don't but found some stuff I did have that may help. I hope it does for your sake. It looks like there's a couple of fuse boxes and relay boxes. Th first picture (below) is a picture of a relay box located in the engine compartment. You should be able to tell if it's the right box by the layout. It looks like in the number 5 position there is a 10 amp fuse but that seems to cover high beams (see description in next picture below). Then there is a multi purpose fuse box and going to gues that's inside the vehicle but when you find it you will be able to tell it's the right one by the layout (see next picture). In the number 10 position there seems to be a fuse that covers the headlights but only if you DON'T have anti-theft. Description of the fuse layout is in the next picture. Then there is the headlamp relay itself. It's located in the relay box somewhere in the engine compartment but again you will be able to tell it's the right one by the layout (see the next picture) It looks like the headlamp relay is in the A-01X position. Wish I could be of more help or at least not having to be so detailed but all I have is the factory service manual. If you do need anymore information please don't hesitate to email me at [email protected] with detailed questions so I can send the correct information. I hope this helps and good luck. here's your pictures.

The fuse box is under the hood on the driver side ! it is called the PDC power distribution center

the rollover switch is in the rear behind the plastic panel rt or left relay is in the main power supply box under hood

You can get free owners manuals online at:

or just type "owners manuals" in your search.

Here is a post I found that worked for my 2005 caravan.

For a 2001 Dodge Caravan: The owner's manual is vague, only stating that all fuses are under the hood in the fuse box, no diagrams. Once you have removed the fusebox cover, the diagrams for what each fuse does is provided under the lid. UNCLEARLY marked is the radio fuse, a 20amp fuse located 2nd row from top to the right of the accessory relay. It is marked: RDO/IP IGN.

The layout should be near where you put the fuses in.  Hope This helps (Please Take The Time To Rate Me)
