I had the same problem with mine the lights not coming up is just the switch, you can get a new one for like 60bucks at a GM dealership. There is a possibility of vacum lines up top you will be able to see.
Sometimes a vacum line will get blown off that connects to a box in the driver side fender
Take a look under the hood on the driver side. There will be a few thin lines and a lil actuator sitting under the cowl.

Baby girl.

on the blazer there is a shift motor.. connected to the transfer case. On the blazer the wires that control the shift motor have been known to drop (sag) down and rub on the bushing of the front drive line. When it first starts happening you will blow a fuse... when it's completely worn through the fuse won't burn out but you'll have to pull that drive line(front) and repair the wires... if your lucky you'll have enough play to re-splice them

It could be a junk switch or it could be bad contacts inside the transfer case motor.. Does the transfer case switch to the selected gears? Everytime? If so, you might try another switch. If it does the same, I would say the motor contacts are bad. Replace the motor if you want the lights, But I personally wouldn't do it until the motor quit switching gears. They're not cheap.
