Bizzaro problem-clock on all the time

Ok here's the setup: 99 Lumina 9c6 car ex FDNY personal vehicle. Had all the lights and trimmings but no holes chopped in it. Has the factory AM/FM stereo, no tape or CD. Radio does not function in acc. position but works fine other than that and clock does not go out, on all the time. Other than that, it functions ok. Pulled fuse for the radio and clock did not go out. Car has SEO accessory package. Could the fuse for that be back powering the clock? Don't really need a dead battery after a few days. Any ideas???:frown: Thanks in advance.

Remove fuses one at a time to find the one feeding it. Unfortunately, with an SEO vehicle, there is no predicting what might have been done to it by outfitters.

Yeah, I figured that's what I'd have to do. Anybody who has had this problem, post it and let me know if and how you fixed it. @ least it was a reputable SEO fitter. FDNY used good wiring and heavy duty relays throught the car. And when they sold it they didn't just snip things. They removed them and replaced what was spliced with new wiring harness and covers.

Ok, went through the fuses and found out the fuse for the instrument panel (I/P) was the one that made the clock go out. But it also deaded the gauges and warning lights. So I'm guessing they may have tapped a power line or something into the line for the gauges and that's what's backpowering the clock. Time to start tracing and digging.:crying:

The I/P fuse should only have power through the ignition switch. One possibility is Fuse 7 (a 5A). It is supposed to power the SEO accessory switch panel, which ties into the I/P power and speedo. There is also a diode which isolates the SEO Accessory Switch module from the interior lighting circuit (which is powered all the time), and may back-feed the I/P and other circuits if the diode is shorted. Pull the interior lamps fuse to find out.

I will do that tommorow, definitely. The fuse I pulled is a 15a "I/P Power", 2nd row down, 1st in line. I will try what you suggested and let you know, thanks!

Ok, update. I have tried pulling every possible fuse and no result. I'm beginning to think it's the radio. There are no more splices left and the harness is clean. Any ideas?:disappoin

The factory radio has a feature where you can push in a button when the car is off so it will display the clock for you. I believe it's the volume knob but I'm not 100% sure. It may be stuck in the depressed position keeping the clock displayed at all times. Try pushing and pulling on all teh radio buttons/knobs and see if the clock display goes out. The clock and station memory functions of the radio have power all the time, and are powered through the same fuse as the cigarette lighter if I remember correctly.

Ok I will try that in the morning, but I belive I already tried it. Still, can't hurt to try thanks! BTW it is the AM/FM w/ no tape or cd.
