Ch3vyDude Posted September 21 Report Share Posted September 21 The heat/AC control unit doesn’t light up at my ‘94 Lumina , did anyone had the same problem ? I’m not sure how to fix it since I couldn’t find the location of the small bulbs .. Quote Link to comment Share on other sites More sharing options...
Schurkey Posted September 22 Report Share Posted September 22 Get a service manual set for your vehicle. Look at the schematic to see how those lights are powered--assure they're actually getting power and ground. It's possible that all the bulbs have failed, but not likely. I don't know about Lumina, but GM has used tremendously-small light bulbs, soldered into place in their sockets, on other vehicles of about that same model year.

Ch3vyDude Posted September 24 Author Report Share Posted September 24 Thanks for that information! I’ll take a look Quote Link to comment Share on other sites More sharing options...
Go4DaMo Posted September 24 Report Share Posted September 24 I think Schurkey's on the right track, there. Mine have gone out for the 1st time in 10 Luminas. It upsets me. But, Ive got bigger fires. Quote Link to comment Share on other sites More sharing options...
White93z34 Posted September 24 Report Share Posted September 24 Back in the day I've had this issue. go ahead and grab a test light and figure out which wire is responsible for illumination but my guess is they have simply all burned out. which is highly annoying given they are all soldered down and what should be a pretty brief project quickly turns into more then that.

Ch3vyDude Posted September 25 Author Report Share Posted September 25 Hmm so finding a used part as replacement could be less trouble, if it works of course Quote Link to comment Share on other sites More sharing options...
