Question about 1989 GMC Suburban
I changed the light switch for the head lights and now the dashboard lights won't work. But all the other lights work.
If ALL the lights work but the dash ...and the dash worked before you replaced the switch its probaby the twisty (dash light brightness) part of the switch its a 3 way switch pull halfway for runners pull fullway for headlights twist right or left for dash lights L all the way for bright ...then click the dome should come on ya didnt say where the NEW switch came from ..................

Most often the tail lights and dash lights share a single feed and fuse.
Assuming you have checked the fuses (probably marked as tail or courtesy)
If you have good fuse and the head light gives a voltage out while in the 'parking light' position (usually between off and headlights) then you need to start chasing wiring.

Make sure that when you check the fuses you use a test light applied to both sides of the fuse you are testing.It can be very difficult to see a fuse that is blown when the fuse is blown near the edges. PS the dash fuse is by itself and needs to be checked when the light switch is on.

You must have a bare wire at the back of your truck that's shorting out where gravel stones have pounded the outside coating off. If you have an after market trailer plug on there, you might want to check that out too. The connections to your main wires from the trailer plug, are never done properly, and always cause problems somewhere.
