On my daughter's 99 Accord. Is there anything common to these two items? All the fuses seem to be good.

 

did you check both inside fuse box ? if so was a aftermarket radio installed ?

 

I checked the fuse box on the drivers side, end of the dash, and the one under the hood. Is there a second inside fuse box?

Also, she had an aftermarket radio installed a week ago, but the light thing just happened last night.

 

I can almost guarentee it has something to do with that. I don't have my service manual so I don't know what they have in common electrically. I would try to take it back to the shop. Did you check if it shares a relay under the dash or in the underhood fuse box?

 

She installed it herself, and she used an aftermarket harness, so it's plug and play. If it shares a relay, I haven't found it. I don't have a manual.

 

Did she unplug the battery when she did it? What kind of a stereo are we talking about?

 

It's a Dual, and no she didn't disconnect the battery.

 

She's lucky she didn't fry the ECU. My buddy put a stereo in his Jetta and fried the ECU, SRS sending unit and an ABS sensor. $1350 later, he still had his factory stereo. Next time tell her to always disconnect the battery when doing electrical work, at the very least so she doesn't get shocked. The electrical problem could really be anywhere...if you can wait until Sunday I'll have access to my service manual, or maybe someone on here can help you. It's gotta be a fried relay or broken connection somewhere.

 

pull the radio back out ane double check the wires the aftermarket plug & play harness wires orange,orange/white are normal ones they are dimmer illumination wires if not used should be taped up as if they touch groung it will blow the fuse or multiplexer unit. then after that check the other fuse box on the passenger fuse box.

 

It's a relay.
