we have water coming in under the drivers side where your left foot would be. We had the roof resealed two weeks ago and just 2 days ago, had the windshield sealed. tech said, you won't have any leak now. this morning after a rain, we had the lead again. does anyone have any experience with this location and a leak?

most likely the windshield. Get a tube of clear silcome and go between the windshield gasket and motorhome with a bead that is thick enough for some of the Silcone to come out after you move off of it. Before it drys or sets take a piece of plasitc and remove the excess silcone. I bought a silcone tool at Home depoit before I sealed mine and it work fine. clean silcone that get on the MH paint with a paper towel. go all the way around the windshield.

How was the windshield "sealed"? If you mean completely removed and re-set in sealant, they you should not be having a windshield leak problem but if you mean re-sealed with silicon, you may still have a problem. The windshields can and do move around if the coach gets a "twist" while moving or being jacked up. Also, take a close look at your "clearance" lights just above the windshield and make sure they are sealed. You also may have air horns on the roof that could be the problem and even your driver side window. Water may show up by your foot on the floor but may have run a few feet before it found a way to get down to that area. I check all of my roof penetrations, my clearance lights and window/shield every 3 months for potential problems. Also, recommend that you stay away from silicon around a windshield. There is sealant designed specific for windshields. Many years of travel trailer and fifth wheel ownership "learned" me this.

Windshield wipers.......Had that before...

NEVER use silicone to seal a windshield! The professionals use urethane and let the unit sit for 24 hours to be sure it's set before moving.

Ditto on the urathane only. I had a small leak and asked a glass shop about my patching it with silicone.

They nearly jumped naked. Told me to NEVER use silicone as it will cause rust problems. They gave a a half tube of urathane for my own use.

Check any antenna penetrations and the marker lights in the area (I used duct tape to verify the leak, then replaced the duct tape with eternabond tape cut to seal).
Don't use silicone.

You might want to check the driver's side window, particularly the window frame drain hole(s). If the drain hole is plugged the lower frame will fill up and overflow -inside and out.

Good idea to clean them on a regular basis.

I'm chasing a leak that only occurs when the slide-out is extended, the large rubber seal is very flexible and is tight to the slide wall -slide has a topper too...

Hope you find it, water leaks seem to be the bane of RVing.

Amen on the window drain holes. Alot of people don't know they are there. Sometimes even they can't drain fast enough during real hard rains. I installed vent shades over driver side and passenger side windows to deflect water.

I agree with the drain holes. I used to have a 57 Studebaker Silver Hawk that the drains were plugged up in the door. One day after a particularly hard rain in Oregon I found the door about half full of water. Cleared the drain holes and a bunch of rusty water ran out for a good long while. lol A few years later I had a similar problem with a Buick... it was the rear window plugged and it over flowed into the trunk.
