Blown fuse?

The other day I jumped in my car to head to work and after a hard start I noticed that my fuel gauge wasn't working (way below empty and no low fuel light on). Today I jumped in to take a look at things and I noticed that my door chime disappeared (have to leave key in to bypass security), the security light is no longer on, the climate control doesn't work, and the passenger climate control doesn't work. It seems kind of weird that all of these would be on the same fuse. If they are then obviously that's all I need. If they aren't, what may have caused this problem?

Oh yeah, I forgot to add. I think there's a short in my drivers side door. When I open it, it seems to unlock the doors when it gets to the first click.

Look in the flexible rubber coupling between the body and door. Broken wires there create all kinds of problems. Very common problem in our cars.

Checked the main fuses and theyre all good. Took the inner door panel off this morning. Ill be checking the wires tomorrow.

Here's a rundown of everything wrong and it all happened overnight.
-no gauges
-no hvac
-no security system
-no door chime
-no power to the spot that you can hook up the obd scanner

checked the wiring. Can't find any problems where you mentioned. It still seems like a fuse problem. How else would I lose all of that stuff all at once. I'm starting to give up hope as I have no idea where else to look. The car starts and drives, and all of my door controls work. If there was a problem with the door wiring you think it would effect something on the door itself. The passenger climate control gauge just shows green bars all the way to the one side and red bars all the way to the other.

Was told by a friend to change the IP/ELC fuse because all of the stuff I mentioned ran through that. Replaced it thinking maybe it was getting some power (to light up the tool) but not enough for the stuff in the car. That did nothing. Read a post online that mentioned a wire in the door causing those problems, but I can't find any damaged wires. I do know that there was a short as it was unlocking the doors when opened to the first notch. After checking, my power lock doesn't work, but power unlock does. Any more ideas would be great. Or anyway for me to check those wires in the door. I tried grounding the light up tool and checking the prongs in the connectors but only one prong lit up, one popped the trunk, and one unlocked the doors. What's the best way to check them?

Just bumping my post. Still haven't found the problem. Fuses all good, checked wiring with a gauge and can't find any interruptions. Went out to a dead battery today.

Can't really help with this one as I don't know the Riviera's electrical system well enough yet, but I feel your frustration. These odd electrical issues, along with phantom rattles deep inside a dash, are some of the most frustrating and difficult to find issues.

I just "solved" a similar problem that turned out to be a bad radio.....

I hope someone can offer a tip.

Check the computer module under the drivers seat for water or impact damage.

Check the wiring under dash (you have to pull knee panels) for damage from mice.

Check the body computer under the rear pkg shelf for damage

Do you have **any** electrical modifications, if so what (stereo, remotestart, etc)

So, basically, your entire dash is out? At this point, chasing something inside a door is the least of your worries. I'll see if I can dig up an FSM later and have a look-see, being that GM removed all of its wiring diagrams for vehicles 1999-previous

Thanks for all of the help everyone. I decided to go through and check all of my fuses again. The 10 amp l/p 1 fuse was blown. Using an LED bus it would light up sometimes and not others so I guess still making some connection?!? Replaced it and got everything back. As far as everything in the dash being out. The stereo is aftermarket, but still had power to that, just nothing else lol. Crazy that a 10amp fuse caused so much to go out. Sorry if I wasted any ones time. I guess it's always a good idea to check, and then check again. I had the door all tore apart and was about to tear the dash apart to check the stereo connections.

Thanks again

Great!

Sometimes the simplest things


I just finished trying to track down a pesky knock/miss that's been plaguing my Roadmaster for some time. It would come and go and was temperature sensitive.

After lots of troubleshooting myself, on forums and with my mechanic, found a bad spark plug.
