A/C and fan control lights

[Biyobe]

Hey all - I just had an aftermarket radio installed and I think they didn't put my E back together correctly... I could have sworn the fan speed and hot/cold indicator lit up... but cannot for the life of me remember if they used to; but it sure seems dark in that area. Can anybody confirm that they should light up so I can go back to the audio place and ask them what happened!!

Photos attached of what I'm seeing

Yes, they should all light up.

The fact that several, but not all, of the bulbs are out seems to indicate that the wiring was disturbed during the stereo installation. The best-case scenario is that reseating the connectors at the back of the HVAC panel will fix the problem. Worst case is that the circuit board has been damaged and will need to be replaced. (I suppose also that there is a possibility that three bulbs burned out before you noticed, but that seems remote.)

When you turn on the recirculation and a/c, do those indicator lights go on?

You'll find some good background information in this thread.

How fast did you notice after the aftermarket install ??? If it's a couple of days sure take it back , it's not hard to remove so they should be able to check quickly . Just to let you know , those bulbs are not cheap across any vehicle brand .

Good luck

List for 79629-SCV-A01 is $10.85; for 79629-S3V-A01, $4.90. Online prices are lower, though shipping cost means you'd only be ahead if the bulbs were part of a larger order. If you're handy, inexpensive aftermarket bulbs can work, provided the leads are long enough.

If this were my car, the first thing I'd do is pull the HVAC control unit and reseat the bulbs and connectors, and see what happened.

PS , these bulbs are not found in your corner auto parts stores or wal-mart . A trip to the dealer for any car make for these bulbs is a must or buy on line ........ Sure you can get headlight , brake , turn and marker bulbs are readily available , but pedestal dash and HVAC bulbs I've found to be dealer only . Even they have to order them and heck yeah , from $5 to $15 for these little puppies is highway robbery , looks like you have 3 out , 2@10 and 1@5 = 25 , you can eat @ Applebees for that .
Aftermarket bulbs (radioshack) (grain of wheat) are just not worth the trouble . Too much work .

Hope they just forgot to reseat them ......

Both of mine went out yesterday too, I gave them both a few big thumps with my knuckle and they lit back up.

How about an update, Biyobe?

Speaking of which, how did you fix your stereo problem back in 2007?

My lights went out again last night, but came right back on when I gave it a tap with my finger. Weird...

One of mine just went out. Taping on it made it work for a few days and now it's just out. I'm just responding so I can find this thread again with the part numbers in case I don't just order from the dealer. They may have it in stock if it's something that is used in a lot of cars. I have replaced thse little bulbs in older (90's) Hondas. Some LED's would be a better solution since they last almost forever.

Mine Re out also. Looks just like ur pic. I thought it was supposed to be like that.
