need some help please have a low horn sound and no start condition after rain. happened twice when dried up will restart. heard about a connector in engine compartment getting wet and causing this problem anyone know which connector. any help would be awsome thanks in advance

 

Nobody had this problem with no start after rain related to wet connector in engine compartment. I read a post before but no information on which connector was mentioned , just that it was in the engine compartment. Any clue which one would be appreciated thanks.

 

Not sure what year of model you have but the all important IPDM is mounted on the firewall behind the battery. It should have a hard plastic cover which slides down over the unit and is meant to keep it dry. The connector at the bottom of the unit is one of the main umbilical cords for all things electrical in our Gs and I believe this is the area which can create problems when wet.

Make sure that IPDM cover is firmly in place and not cracked. Check your hood's weather stripping around that area and see that the windshield's drain is clear, etc.

Hope that helps.

 

Hi 13_SKYlineSedan thanks for responding I have a 2008 g37s, I think i found the connector you are referring to. I will also check weather stripping and windshield drain.
