window leak

I have had the same or similar issue as the water comes down the passenger side windshield post and comes down in the cabinet above the passenger side window. What I found was the front air conditioner was where the leak was coming from, I have replaced the gasket seal from the air conditioner. I also had leak problems when we run the air conditioner in the summer and that leak comes from the condensate drains be plugged up. So in the near future I plan on removing the cover and see if I can access the condensate drain pan and thoroughly clean it. My motorhome is 16 years old so the condensate pan could have a lot of build-up in it. If you should decide to remove your air conditioner make sure you tighten the four hold down bolts after each trip for at lease a couple of trips. Hope this helps.
