Welcome to the Forum.
According to this site, it could be an issue with the CAN bus. U0164 Lost Communication With HVAC Control Module
Have you tried a Master Reset and/or negative battery cable disconnect for a few minutes?

Starts at the bottom of page 380 of your Owner's Manual. Also, please see the PM I sent the other day about adding your Explorer's "Trim" level.

Update.
I just found out that in my fusebox some place that were supposed to be empty had some fuse
number 20, 30 and 31
I wonder if it can create issue on my car please.
Knowing that my AC doesnt work also my right windows doesnt work too
Who ever have solution or answer could help me please.

I think it would only cause an issue is those locations were actually wired. Since they are supposed to be "not used", I have no idea where the wiring, if any, would go.
Did you check fuse 26 for the right side front window? How about fuses 3, 16 and 38 in the engine bay fuse box for the A/C? Saying A/C doesn't work is sort of a general statement. Is the compressor working? Is the A/C refrigerant fully charged? Are you getting any sort of air inside when the blower runs?

About the A/C this function is greyed out on my dashboard no way to turn it on this is my main issue also it appears that my passenger and rearview windows doesnt work at all.

If the A/C is greyed out, that means it is unavailable to use? Did you ever have it working? Also, have you checked the fuses for the windows?

since I got the car it doesnt work thats my main issue I also thought that it all related because A/C greyed out and electric issue on windows.
I red on same forums but i am not sure

Please add the trim level as requested before in my PM messages. Thanks.

Peter.

Hello I added trim level.
Last day I unmounted and remounted the dash.
Once I turned it on car started for 10sec then turned off. since cant start I checked but it seams like ECU burned down I dont know why.
Do I have to buy another ECU if yes do I have to reprogram it and also with which programmer?
Thanks
Best Regards
