I have an A/C panel that has garbled digits for the temp indication on the passenger side. I have read somewhere how to fix this. Searched the forum but cannot seem to find it, anyone?!

I don't think I've ever seen a fix for this, but I have the same issue as well, so I would be interested if there is a DIY Fix for this.

in the dash cluster are probably what you are thinking of as the pixel repair.
Can't think of any repair other than replace bulb on the a/c unit and that won't fix a bad liquid crystal segment.
unless I am wrong r/r unit with a used one is the only solution

Yeah maybe I did mixup the cluster dead pixel fix!? Wasn't that all about soldering? Has anyone tried this with the A/C display yet?

i had a bad lcd on my climate control and i had to replace it with a used one , but now i have an issue with the one bought , i cant turn the ec light off any idias please

ohlord

can't turn the e/c light off it means your a/c compressor is not operating.
Run the diagnostics in the climate control module and see what's wrong
Probably low on r134a and system needs leak checked repaired and recharged

After some reading up I've ordered the tool to remove the A/C control unit. I'm guessing some LCD segments not working must be a loose contact thing somewhere like the cluster flatcables. I'm going to pull the A/C unit and take it apart and see what's there to find and fix...

Let us know if you find something. I think I did that and couldn't find any cracks or broken connections in the solder. I'd be intrested to see if there is a connection you find with a bad contact or something else. I'm hoping (for all the good reasons) that you do find it.

On my 1999 Mercedes Benz E320 Wagon, I had the same issue but this was after cleaning the dash parts with cleaner. Moisture could be the culprit.

Here is some info on how to open it up once it is removed:

I tried to dry it out but the LCD still has issues. Does anyone know where or how to get replacement LCD screens? I really am not in the mood to buy a whole new unit!

There are many so called fixes,however after reading,most if not all do not work--we just live with it and remember he numbers
