When I unlatch yes the windows go down
yes the key fob stopped Working at the same time
i’m not sure how old the battery is, but the car starts just fine
I clean the battery terminals and yes they are tight
No the car has not been driven on salty roads
Yes the car was stored during winter for the most part I did drive it a few times but never put the top down
i’ve owned the car1.5yrs and have never had any issues!
