Hvac controls not illuminating on 94 Lumina

[NCTyphoonKid]

Anyone ever had a issue with the hvac controls not illuminating? The red indicators work for each switch as does the fan speed just not the illumination ones. From what I can tell they appear to be soldered in? All other illumination lights work for gauges and radio

Yeah, likely soldered in. Doesn't mean you can't unsolder the bulb(s) and solder in new.

My Regal did this, I had to get new bulbs from an electronics supply and solder them in. Could replace them with an LED and a 1k resistor to limit the current.

..if one replaces the incandescent bulb with an led it sort of negates the load saving on the circuit if one has to install a resistor to limit the amps draw.

It's more about voltage drop, a typical T1-3/4 LED is only 1.7v. Current draw is far less than an incandescent bulb. That would be a project though since it may dim different than the rest of the dash and the resistance would likely need tinkered with. 

The place I got my bulbs from specialized in repairing and restoring audio equipment,  like rack system amplifiers and such.
