Chrysler 300c immo problem

Hi guys! I have a problem with a customer's Chrysler 300c. When the car gets wet on the front right side, that is to say from the driver's side roof to the fender, the car no longer starts and gives immo problems. From what I know the car has already been to several garages but the fault has not been found. There do not appear to be any water infiltrations or visually damaged wiring, and the strange thing is that if the car remains dry or wet in other places, it never has problems starting, furthermore if the car is on and gets wet it works correctly until it is turned off and then does not start again. Has anyone already experienced this? Advice?

Maybe network issue or TPIM Module the fuse box in the engine bay on the passenger side is also kinda like the BCM it controls a lot of things I've seen those act up when a little moister is introduced but this is my guess
