Trunk water leak on left side - 2007 Nissan Versa 1.8 Sl Hatchback

Is it AC condensate or is it antifreeze?

You must have a leak, check the seal for the trunk and make sure it is properly installed all of the way around. Also remove both tail lights and make sure there is not damage to the panel behind them. remove the side carpet panels in the trunk and look for signs of water trickling in. I have actually had to remove all of the trim and carpet in the trunk of a car and climb in with a flashlight while someone else sprayed the back of a car at all points and look for a leak. Good luck with it.

Leaking trunk seal or rear window sealer also check the tail lights are mounted properly and that the trunk is closed all the way

Check the sound amp in the trunk on the left side if I remember correctly. Also make sure the trunk seal is not allowing water to leak into the trunk. When it does it tends to leak right onto the sound amp which shorts it out and you end up with no sound from the audio system. If the radio itself does not power up then its probably the radio itself.

check trunk is it back there to check seals around doors and trunk

When diagnosing a water leak, here's a handy tip. Check the accumulated water. If the water is dirty, look for leaks from the underside of the vehicle (floor, wheelwells, etc). If the accumulated water is clean, look for leaks from the topside of the vehicle (trunk seal, window seal, etc). To find where the water is coming from, shut yourself in the trunk with a flashlight and have an assistant run water over the trunk with a garden hose. You may have to remove some of the interior trunk trim to see exactly were the water is coming from, but chances are you'll find it. Also another common cause of water leaks are from impact damage, so check for collision damage repair. while your in there. -hope this helps.

Mother nature is too slow in finding leaks. Have someone small get in the trunk with a flashligh and watch as you run a hose over everything. LET THE PERSON OUT!

TAKE IT TO THE DEALER, THERE IS PROBABLY A TECHNICAL SERVICE BULLETIN ON IT AND THEY WILL BE ABLE TO QUICKLY AND ACURATELTY SOLVE THE PROBLEM.

Check for defective spot welds around the plastic inserts on the left and right sides of the trunk. If the spot welds burnt through the metal, there will be holes were water can get in. Use some JB Marine Weld to seal up any holes or cracks in the sheet metal. Also, check the rubber drain holes under those inserts, that are in the sheet metal of the car, to make sure they are not blocked with road dirt. Also, check the weather stripping on the outside of the car, adjacent to the trunk. If the rubber and chrome trim weather stripping is pulling out (on the exterior of the rear quarter panel), then water will leak through the little plastic attaching screws and into the trunk beneath the plastic containers on the left and right front sides of the trunk.
