My car at day/night runs perfectly.. but at soon it rains and I turn on the A/C the car starts to die..

why???

 

only in the rain or only when the ac is on?

 

I think you should let members know what kind of car you are troubleshooting here..

 

true sorry hahaha Ej1 D16z6... all stock...

and yes, only in the rain..

 

check your wires and dizzy cap for cracks, when moisture gets in there it causes rough idle and missfires and poor starts

 

Wires as in spark plugs?... Ill change the dizzy cap

 

Yea the spark plug wires

 

They're new... bought them like 2 months ago.. less maybe...

if its not the dizzy cap? any other suggestion?

 

I just went to my car in the garage.. Left it in idle with lights..a/c..radio..and the battery died... Battery reading was 13.7 is the alternator the issue??

 

If the battery was reading 13.7 then the battery didn't die and that also means that the alternator is charging and if it's not raining in your garage then it has nothing to do with rain like you originally posted.

 

No no... The issue was during last week.. I tried this now just to check if its during rain or not
