Check fuse for parking lights (same circuit) Check bulbs could be a bad headlight switch
could be a fuse blown out
check the fuse for dash lights
There are several things that can cause your 2000 Cadillac dashboard lights to quit working. The most common cause is a blown fuse.
Same fuse as tail lights
Probably a fuse, check to see if your horn works, really!
Make sure fuse is installed and not loose - same fuse controls parking/tail and dash lights
Check parking/tailight fuse
Which lights? Instrument panel? Dash? Overhead? Ash Tray? Glove box? Also, which model of Corolla?
Fuses
No, this is not normal. You have a problem.
Probably the Tail light fuse is blown. You also lose dash lights when this fuse blows also.
If you dash lights are not working check that your parking/brake lights are working also check fuses for cig lighter and interior lights that may help get the dash light working again.
