My problem is that when I go to turn my display lights on(speedo, radio, and all the others) they don't get brighter. I've been driving in the dark for the last few days. headlights and cab lights works, just replaced the headlight switch. would this be the dimmer switch? or is the dimmer switch part of the headlight switch? Thanks

 

the dimmer switch on my 89 is built in to the headlight switch. Have you tried turning the **** on the switch any? I think you turn it clockwise for the dash lights to get brighter.

 

They stay the same even if I turn the ****. They stopped getting bright about a month ago. Thanks

 

You said you replaced the switch with a new one right?

 

yup, during the summer

 

I am out of ideas. Call me crazy but i'm just wondering if it could be the bulbs themselves

 

i was thinkin that @ first but the radio lights are supposed to get brighter along with the dash lights. the radio light works fine during the day.

 

Are there any loose wires?

 

I'm not sure, ill check tomorrow. oh by the way, all of a sudden my boost gauge reads 23psi on the highway. i don't know what happened? is yours still reading 10psi?

 

yes, mine is still reading 10psi. What type of guage do you have again?

 

http://www.glowshiftdirect.com/white...uum-gauge.aspx color is stuck on red

 

I have the same guage except the one with the black face. You said the color is stuck on red? Is only the needle red? if so then you dont have 12 volts going to both positive wires. You should have 12+ on purple, orange, and yellow. I just tied the orange and purple to a switched 12v sorce and ran the yellow into my running lights.

 

I mean its only lights up red because the button to switch colors is messed up. gonna see if needle nose pliers will help with that button.

 

ok, When i was installing mine i noticed that the front of the guage can turn and mess the button up. Luckily mine came right back. You might also trying to see if the button is twisted and spin the face of the guage back around.

 

I remember fiddling with the front part, I have to check that tomorrow and see if the button will work. We'll have to continue this conversation tomorrow. work in the morning good talkin to ya
