exterior lights won't go on

I have a 91 Accord EXR. The exterior lights won't go on now for some reason. Is there a fuse or relay for just the marker lights and tail lights? I checked all the fuses and can't find anything wrong. Underhood and interior fuse panel.
All the marker lights and tail lights won't come on. The interior lights work as do: dash, glove box, vanity mirror, turn signals, hazards, headlights, high beams, brake lights, back-up lights. The light switch seems to work because the headlights come on when you turn it and so do the dashboard lights.
Any help would be greatly appreciated.
Thanks,
Tony

Sounds like a wiring problem. According to my Chilton's wiring diagram, fuse 23 is the one. But it also controls the ashtray light, glovebox light etc. So, since you say those come on, it doesn't appear to be the fuse that's at fault.

Thanks, I'll check fuse 23 again. Not sure where to start with the wiring. Could be anywhere...

You're right about the last part, I'm afraid.

Have you installed a new cd deck recently? When i bought my accord we realized on a test drive that we also had no park lights...etc like you are saying...as it turns out the person who reinstalled the factory deck had run a screw through some wires...check the wires to the ashtray/glove box behind the deck

94accordVTEC - Yeah, I did just install a CD deck! I put in an AMP and speakers recently too. Hmmm, I'll try that. Thanks! Makes sense. AccordCodger said that the wiring diagram show ashtray light etc.
I'll try anything so that I don't have to go through all the wires. I hate wiring problems. It usually ends up being something simple too.
Thank you both for your help!

It was my daytime running light relay. Same problems with these as with the Master relays. The solder contacts aren't very good. I took it out re-soldered all the connections, put it back in and the lights were perfect again. The DRL relay under the dash, on the left side of the car, near to the door. Easy fix. Take it out re-soler it and put it back. If anyone has intermitent satrting problems with the Accords, you can do the same thing with the master relay. I did that too and it's been almost 2 years and no more problems.
