No Climate Control lights

[Herman8r]

My lights on the climate control and also on the light switch itself are not working.
The dimmer switch still operates my radio, overhead console & instrument cluster.
I checked the fuses and all seem ok.
Any Ideas?

Bulbs are burnt out, pop it out and replace the bulbs.

Thanks cerberusiam! I thought that might be a circuit board with fixed lights on it.
Do you know if bulbs are locally available? That way I can purchase them prior to removing the components.

Not sure, little round sockets with bulbs in them. I just have't had a chance to go to NAPA and check if they have.

 

[Herman8r]

Thanks. I will check it out.

If you have dual zone Aircon then you can't change bulbs, they are soldered in.

I finally had a chance to pick up bulbs & replace them. Prior to taking the center panel off ----the lights came on last night...well for a while. They blinked a few times then one went off then all three went off. So I took it apart today. As it turned out the bulbs were good. I put a multi tester on the contact areas of the board and no voltage with light switch on. Other panel lights work on the instrument panel an overhead counsel.

I am thinking maybe the board might be bad? Just a guess.

I found these on ebay, T5/T4.7 got 6 for 5.99. twist off and on install. they have different colors, LED's, but I just typed climate control bulbs for what vehicle your looking for.

Thanks for the info. The replacement bulbs I used the first time did not work.
Purchased some LED's that fit perfectly. Just put them in and they DID work. All seems well.

Now I have to troubleshoot a new issue that happened yesterday. Had a hard time starting my truck. No engine turn over. Finally started. Left the engine running, opened the door & the dash lights started flashing and horn honking. Similar to backing up with the drivers side door open (annoying). Also the gear indicator light do not light up when in park or reverse. I am thinking it is the Gear Range Selector on the trans. I have replaced these quite often as they leak. Somewhere around 4-5 times so far. So I am thinking this may be the issue.
