Check charging system

When raining...is water getting on belt to where it is slipping on pulley? When this is not happening have you load tested the battery and checked voltage of alternator while running? How old is belt and is tensioner pulley weak?

any moisture under the dash ? may be the windshield is leaking and causing problems

My car is doing the same exact thing as we speak but mine does it all the time even when it's not raining and it will not start when the lights are on the dash I've been told it's the cluster because that communicates with the PCM and everything else

And what's weird when all the dash lights come on and check charging system comes on the AC does not come out cold

Mine is doing the same, when it rains, and now when there is a lot of moisture in the air in the morning since fall is getting here. My computer shuts down and tells me it is saving the battery. dash light go out, radio goes out, fan stops, windows will not work and then it comes on and shuts off again. does it over and over again. Once it dry's out in the sun, it stops doing it. I had my battery tested and my alternator and both were fine. It has been doing this off and one now for 3 months. Now its daily every morning.

Did anyone find a solution or at least figure out what is up. I have the same thing
