Default HVAC Display- 2002 vert

The lights on my HVAC display just went very dim and are not visible during the day. I'm less than impressed with the search feature on this site. I suspect this had been addressed before. Anyone have a suggestion or link to a previous thread? Thanks!

I haven't run into this yet, but expect to some day. I believe this is the thread that covers that issue for the dim HVAC display.

Anybody who can solder can fix it .
Here is a video of how to remove the HVAC control.
This is a pic of the board. The 8 circled resistors need to be resoldered. In my case 5 of the resistors had fallen completely off.
The original resistors are obsolete and not available anywhere I could find but I did find a suitable substitute. I will also include
a close up of the board so you can see what I used.

Travis at Vettronics did mine - and he uses the correct bulbs. The display needs a series of resistors resoldered for the dim LED display and it's only a matter of time until the incandescent bulbs start going out. Any questions PM me.

For the price and the warranty it was a no brainer.

I am pretty good at soldiering, but I didn't have a small pen soldier at the time, I took mine to a local guy, $60, fixed. If you are gonna try, use a small one, have some magnification. Large iron can apparently heat up the resistor too much and damage.

Nov 2017 I took my unit apart while doing a radio change out and resoldiered the resistors. The display was out when I had bought the car in March '17. One was totally loose on both ends. Still working fine and dandy. Much easier job than taking the ECBM apart and resoldering that problem.
