SOURCE: 2003 Seville STS low beam headlights don't work
ya its is prolly the bulbs, open your hood. look behind your headlamps, some have covers for the low beam and high beam. if there are covers turn on your high beams so you will know which bulb is your lowbeam. if you can unplug them. after cover is removed and you can acces the bulbs. they either twist out, lefty lossey. or they have little metal retainers that you have to move a certian way before you can swing the retainer out. its like a door you just have to unhook the proper side of retainer and the other side will be hinged. use a flash light and look at it close. good luck

Hi Clark,
The headlamp system in your Eldorado is controlled by the Body Control Module (BCM). Besides the light switch on the dash (which only provides grounds for certain BCM circuits) There are 10 different fuses, 5 relays, an ambient light sensor, a headlamp dimmer switch, the BCM and the Instrument Panel Cluster (IPC) involved in your headlamp circuits.
You asked about an easy way to check the switch...
The easiest way is to connect a scan tool and verify headlamp switch input at the BCM as you operate the switch and watch the BCM data.
I recommend that you begin this diagnosis by scanning your computer network for fault codes that may lead you to the cause of the problem. Please note that MOST generic OBD scanners (code readers) cannot access the BCM or IPC data.
SOURCE: power seat on 96 Cadillac deville wont work after replacing stereo. Any Ideas?
it is not a fuse, it is a circuit breaker in the fuse box, which i believe is under the hood on that car, i would check for bare or shorted wires behind the stereo before doing anything with the power seat.

check your fuses that are in your paneling under your steering wheel and double check ur power and grond wires
