Hey everyone i have tried going through the fourm to see if there has been a similar question but as of now i can not find one so here goes.
 
I have a 99 blazer, when i turn the headlights on i have no dash light of any kind not even in the climate control group. my radio lights go out as well as the digital temp gauge on the overhead console my digital lights for PRND321 work as well as for my milage they both go dim as they should but nothing else. I have replaced the hdl sw and the radio still nothing, i checked all fuses even under hood they are all good. any sugestions???? pls hlp thank you in advance.

I would say the headlight switch in the left side dash is shot. That controls the auto headlights and dimmers in the interior. About $55 US and have to remove the trim - 1 screw above gauges, and then the 3 lower under wheel and the others are plastic snap ins so release on slight pull. Do not break the harzard button on top of syteering wheel off doing this! It is kinda in the way so be careful.
Assumes the alternator is good and gauge shows about 14 Volts - if it drops when lights come on get a load test on that first.

are you talking about the actuall headlight switch in the dash the one that tuns them on and off, if so that has already been replaced, if there is another on you are talking about i am not sure

That was the one. If the dash has been out for a heater core you may have some bad connections. Next arae would be the door jam switches - all work and none broken and shorting. Then on to the multifunction switch - activate high beams then lows and see if that effects the outcome.

Thanksfor all the help. My high beams and low beams work fine,do these have a sensor that determins night from day? when i start my truck when it is dark out i dont have to turn my headlight switch on my headlights are already on but when it is daylight i can use the switch to go from daytime running to headlights! Still no dash lights either way

I have a 2000 Blazer I just purchased recently. The dash lights flicker constantly. Is this normal in a GM product as I have never owned one before? Also headlights come on when starting and stay on unless I push the dome override. Is there anything to do to fix this problem? Thanks.

#7 of 13 91 blazer dash lights out!!!!!! by vhreece

I have checked all the fuses and they are fine. My dash will not light up, cig lighter don't work, and I can't tell how much gas in the tank. I can't even tell how my speed is, no dash lights at all. The dash panel is digital as well. The radio does work, but can be shakey at times. What is a person to do?????? Could it be electrical?

#8 of 13 Can the dash lights be replaced?? by jpmccr

2001 Blazer LT - 120240 miles. I have now about half of the lights working on my dash and climate controls. The radio lights are going out as well. I used to have all of the them but it seems that ever so often another "dies". Any help or suggestions would be greatly appreciated. It is very frustrating. . . . . . .

yep, the lights are replaceable. The instrument panel will have to be removed, as will the climate control head. There are usually little twist sockets from the back that are removed with the bulbs in them. Replace the bulbs and you are good to go.
 
The radio lights may not be quite as easy, but the radio is easy to remove and you could then take it to a repair shop and have them replaced.

I replaced the "bug" lights in my 1991 S10 Blazer temperature conrol panel yesterday. Two screws hold the panel to the dash and are located underneath the control panel. . Remove the two screws and the panel assembly lifts out.Pull out the assembly until you can access the light bulb sockets. The two sockets in the light harness accepts two #194 bulbs..Reinstall the temperature control panel in the resverse order that you removed it.
