My climate is working nice 98% of the time. But sometimes when i start the engine (and only during the start) some strange things can appear: - all the LED of the control panel blink. or - strange clock display or - Control blocked Did someone of you have the same gremlins. I shall clean the connectors inside the unit, do you think it is enough ?
I'd do a search on 'hidden fuse' as there is a well known issue. Does you clock keep resetting to 00:00 and flash?
No the clock is working correctly... When the gremlins appear, sometimes the clock is showing strange digit combination, but if i restart the engine, it comes back to normal work.
Happened to me too, exactly as you described. Two things: in my case it started happening in winter - say... 1 out of 10 starts - when the battery was not cranking its utmost amperage. As the season got warmer the incidence of these faults diminished (but did not disappear). I then decided to remove the HVAC control unit and cleaned + reseated the main connector. I did this a few months ago so my recollection isn't crystal clear but I did notice that there was also a missing screw in the electrical connector receptacle on the HVAC control panel itself. This, in turn, allowed the connector to wiggle a bit which, in my opinion, likely caused the occasional fault at start-up, as you described. We are still in the middle of summer (so my new-ish battery isn't afflicted by low amperage starts), but since I did what I described above the fault hasn't reappeared. Hope this helps.
If your control panel has black rear cover, you may wish to also inspect and clean the internal connectors as shown on these pictures (posted by a member here some time ago).

Just a few word about the result... My control panel has a white rear cover, so i just cleaned the external connector. Now, it sounds perfect. Let's wait 2 or 3 weeks to confirm the result....
