Clima panel problem

hello again. I have a problem that persists with the climate panel. The car is hybrid, E300 hybrid. I changed both batteries and what to start and accessories, to exclude the problem of voltage ?! the problem is that the climate panel goes out and lights up on the go. it actually blinks and at some point it stays on. this came out of the blue. not necessarily in cold weather. the idea is that he doesn't do it all the time. no error occurs on the STAR tester. Can you give me some advice ... where can I start the investigatios? thanks a lot

STAR tester, is the software Xentry? Any other symptoms?

Post up your VIN and we can provide a wiring diagram for the unit if you decide to check for powers, grounds and signals. Have you removed the Clima unit? Maybe it just a loose connector from prior work...

Hello. exactly with Xentry software. no I didn't remove the climate panel. I will try. I hope it's an easy fix. it has no other symptoms or errors. VIN is WDD2120981A819994. yes, I think that the scheme helps a lot to know where to start investigating. or at least I see what "weaknesses it would have"

If the guidance in the bulletin doesn't resolve your issue, here's the wiring diagrams for further troubleshooting.
