I have saturn ion3 sedan 2005 . My stop light not working. I checked the switch and fuse. They are OK. But didn't find relay. Where I can find it? Thank you.

There is no relay , the BCM - body control module controls the lights !

ok, your other question was too vague or you posted that question by accident without the specifics

this fuse for your fuel pump for your 2005 Saturn Relay minivan is in your owners manual, i'll link a pdf version in case you don't have one in the glovebox

page 5-12 shows you where the fusebox is under-the-hood. you want this one vs the other one inside the passenger compartment.

goto page 5-100 for the diagram of the fuse locations. you should also have this same diagram printed on the fusebox cover.

fuel pump fuse is postion #2 on that diagram
fuel pump relay is next to the horn relay

You mean the door ajar alarm ?
You could probably pull the fuse for the interior lights to make it stop.
Chances are one of the door sensors has failed.
The PSD fuse is for the power sliding doors.

Checked fuse ok / checked stalk ok / checked wires at stalk none cut / checked relay ok so where do I go from here?

fuse ok but may be the relay is not ok sir
check the power windows relay
and have a good day sir

Check fuse for horn and for dash lights. If the interior lights work then suspect dimmer switch for the dash lights. If you press the horn button do you hear a click under the hood or inside the car? If you do not then the fuse is blown and if the fuse is good then the relay may be suspected bad. If the fuse is good and the relay clicks then suspect the horn to be bad. If fuse is blown and you put a new one in and you push the horn and the fuse blows again, then disconnect the horn before replacing the fuse again. Then push the horn button and see if you hear the relay click if you hear a click the the horn is bad or wiring butmost likely the horn. If you have the horn unplugged and the fuse is good and you push thee horn button and no relay click suspect the horn button to be bad. Hope this helps.

There IS a fuse under the hood...the green 30A big boy labeled power/convenience. Use a multimeter to check power coming into the relay...if it's not there probably the fuse. If it is there, could be the switches.

If it's the fuse, go to a junkyard and get one cheap. But then, they're pretty cheap new too.

Since your "check engine" light is on you can get a free scan at Autozone or Oreillys. They can sell you a part and may have a diagram about where it fits. Just speculating it may be a coolant temperature sensor.

It sounds like you are not getting into the Cold Start mode.

Check the brake light switch, it might be bad.
It's under the dash, near the top of the brake pedal, connected to a bracket.

if your lights are dim,your regular lights are not coming on.raely but possible that both lamps blew. the daytime running light module is probably the cause.it has a relay inside of the sealed box and they freeze up sometimes.if your dtr works,the high beams should as well. these are things to check....bulbs,the fuses,wiring and the daytime module.modules are about 100 bucks or so,and if you follow the headlight wiring sometimes you can find it.
