Does this only happen when you run the A/C or can you tell yet? Could be a leak in the windshield seal or a drain for the cowl allowing water to build up and then run inside the heater itself then out the lower heater ducts, I have seen some leak around the roof rack mounts and run down and into the floors.


I did replace windshield as precaution. I also did feel inside heater outlet, which is dry. I do not know how to check if roof rack is leaking. I do not know what a cowl is to check?


The cowl is the area just below the windshield, it is where the heater and A/C system takes in the fresh air, the drains are located way down low close to where the fenders are bolted on, sometimes you can see them with the front doors open, but usually it is a feel operation. Testing for a roof rack leak requires you to tape a garden hose to the rack where it is mounted and then run water over that mount and watch for any incoming water, this will have to be done to all 4 mounts, if you do find a leak then the rack will have to be removed and resealed, and sometimes that is not easy due to corrosion.


Thanks so much for the follow up and info. I will find this leak
