Ac condensation running down inside rear cap

[Glenn and Kathy]

AC condensation not running off roof at drip rail. It is coming down the inside of the rear cap. I see no indication of leaking inside coach. I pulled both covers and there is no blockage in drip pan. it appears to be running out onto roof. Coach is a 2006 National, Sea Breeze LX. Would appreciate some help.

If its running out on the roof then getting in the end cap so does rain,you might want to reseal. There is a gasket that seals te AC to the roof the unit might need tightening.

You also might want to consider that the condensate drain line is blocked and the secondary drain or overflow drain is where the water is coming from. On homes, you have a condensate drain and also a overflow drain that comes out of the wall usually above a window, so you will notice that you have a problem sooner. Motorhome ac's are the same as homes, just a smaller version.
