I would suspect a ground problem. Saying that, check the brake light switch.
To jump-start a 2000 Oldsmobile Silhouette, first, ensure both vehicles are turned off. Connect the red (positive) jumper cable to the positive terminal of the dead battery, then attach the other end to the positive terminal of the working battery. Next, connect the black (negative) cable to the negative terminal of the working battery and attach the other end to a grounded metal surface on the dead vehicle, away from the battery. Start the working vehicle, let it run for a few minutes, and then attempt to start the Oldsmobile.
There is no fuse just for the speedometer. If the speedometer is not working, you may have a problem in the dash gauges cluster, or a vehicle speed sensor problem.
Blown fuse?
the first will be check for a blown fuse at headlamps fuse box
A very common cause for heated seats not working is that the heater element has burned out on either the cushion heater element or the seat back element. The way the system is wired, if one goes bad, neither will work.- techJK ----------------------------------------------------------
To jump-start an Oldsmobile Silhouette, you'll need a set of jumper cables and another vehicle with a functioning battery. First, park the working vehicle close enough for the cables to reach both batteries, then connect the positive (red) cable to the positive terminal of the dead battery and the other end to the positive terminal of the good battery. Next, connect the negative (black) cable to the negative terminal of the good battery, and attach the other end to an unpainted metal surface on the engine block of the dead vehicle. Start the working vehicle, let it run for a few minutes, then attempt to start the Silhouette.
If headlamps are not working but the parking lights are working can it be the fuse that is faulty
The starter relay on a 2001 Oldsmobile Silhouette is located in the under-hood fuse box, which is situated near the battery on the driver's side of the engine compartment. To access it, you may need to remove the cover of the fuse box. The relay is typically labeled on the underside of the fuse box cover, making it easier to identify. Always ensure the vehicle is off and take proper precautions when working with electrical components.
My 2000 has an intermittent problem with the rear fan quitting. I found the plug on the fan to be loosing contact.
Why is the electric coolant fan in your 1989 Oldsmobile cutlass cierra not working?
It is due to your daytime running light not working properly or a burnt headlight, check your bulbs. I had the same problem and that was the problem.
If the power door on your 2004 Oldsmobile Silhouette is not working, it could be due to a blown fuse, a faulty switch, or a malfunctioning motor. First, check the fuse box for any blown fuses associated with the door's power system. If the fuse is fine, inspect the door switch and wiring for damage. If those components are functioning, the issue might lie with the door motor itself, which may require replacement.
