If you have a trailer hitch, check your light connector from underneath where the wires connect to the vehicle wiring. Looks like you may have a short.
There should be a roll switch right next to your light switch on your dash to dim the lights with.
There is not a fuse, only a relay box, that consist of like 3 relays. One for running lights, one for bright lights, and the other is for the dim................The box can be found in the back of your glove box on the left, on the back wall. There is a fuse for your lights on the side of your dash, open the drivers door and you will see a panel on the side of your dash, all fused for Blazer is here..........
Check to see if the dash lights dim or if the tail lights come on when the light switch is turned on. If these other lights work then check for a headlight relay. Most likely causes are either the switch or the relay.
I have a 1983 GMC Sierra it has no dash,tail lights an brake lights are very dim
If you know where to change the odometer/tripmeter display... Instead of pushing that control, turn it counter-/clockwise to dim/brighten the dash lights.
Check your alternator it could be malfunctioning. Sometimes it gives you warnings like this.
dial right hand side of the steering wheel
because it is using up lots of power :)
You turn the trip odometer button on the dash.
have your battery and alternator checked but first check to see if switch for your dash lights are just turned to dim
Most dash lights have a setting knob to turn the dash lights on and off and to dim them, maybe this switch is off.
The dash lights will dim when the head lights come on. Check for a dimmer switch on your dash. It allows you to adjust the dash lights so they are not too bright and affect your nighttime vision. It may be set too low.
