This has happened before but has never been this hard to fix.

In the past it has gotten wet on the passenger side of my vehicle. I've let it dry out for a few days and everything has been fine. This time though it's been almost 2 weeks and it still isn't working.

What's happening is the Key FOB doesn't unlock the vehicle or pop the trunk so i use my key to open the door. That action causes the alarm to go off.

I've tried to do the key reset but it doesn't recognize the key at all.

1. Just wondering what is getting wet that would cause this?
2. Why isn't it acting like before and just drying out?
3. Where is the water coming in from?

thanks for your help in advance

 

Welcome to the forum. Water inside the cabin? I think it's about time you took it in for service. Otherwise, you can expect more and more electrical gremlins the longer you wait.

 

i've taken it to a couple shops and everytime they have gotten to working on it there's nothing wrong and i get charged for a diagnostic that came up with nothing.

 

I don't know if I can help with the leak without seeing it for myself. How wet did it get? After a rain? After using A/C? Any collisions involving the passenger side? Is there a sunroof, and if so factory?

 

how wet? - a puddle on the passsanger floor mat....not just wet...there was standing water

it was after a heavy rain (vehicle was parked at my shop)

not using a/c

no vehicle accidents at all

no sunroof

alarm system is factory

 

So, you're saying "a couple shops" you took it to couldn't find the source of the water leak? This isn't going to be easy, then. Until you fix the leak, there's no point in chasing after electrical gremlins. If you feel like getting your hands dirty:

Take the sound insulator panel off from underneath the passenger side dash and then look for telltale signs of water intrusion (water stains, rust on exposed metal surfaces, bolts, and screws).

Open the hood and inspect the side and base of the windshield as well as the air inlet grille panel in the cowl area. Look for missing adhesive or damaged seals, cracks, gaps, etc.

Spray water in suspect areas and see if you can narrow it down.

A few possibilities are voids (of sealer) in the "A" pillar along the windshield, void in the seam sealer in the baffle area behind the passenger fender, void in the seam sealer at the tab in the passenger wheelhouse or voids in the seam in the crowl at the front of the door area of the passenger side. These are just suggestions and are not meant as a diagnosis.

I encourage you to have the vehicle inspected by a certified technician for an official diagnosis.
