Driving home on Tuesday, we went through a pretty good downpour and the windshield fogged up. Turning on the defroster (we had it on max heat and max fan, but also tried other settings) only increased the fogging. DW was pretty good at wiping in time to the wipers, but it appeared as if there was fogging that was not being removed by her or the wipers on the outside.

Finally we turned on the generator and the A/C and we were able to remove enough ambient moisture so the the defroster was able to work, but that doesn't seem to be a very elegant process. Driving with almost no view of the road was NOT fun.

Any suggestions on what we might have done wrong or what we should do differently the next time we encounter rain?

Supply line disconnected to the vent?

EXACTLY what COR said mine were not hooked up behind the stereo panel you can push them up from underneath by the genny have someone pull them up and stuff them over the tubes. while you feed them upwards if they are too short.

Mine did the same thing on the TS and it was loose defroster hoses where they connect to the vents like Johnny's were.

Thanks although we were getting hot air from the vents - but maybe it was just a lot less than it should have been.

How do I get to the connection points?

Pull the 8 or so screws from the bezel on the stereo and cameras lay a towel down flop it forward ON CUPHOLDER AREA, disconnect any plugs limiting it to rest on towel look straight back you will see the 2 black vents and the hoses will look to short just tug on them and stuff them over the black vents.

If you are getting good flow from the vents, make sure your air conditioning compressor is engaged at the engine when your defroster is engaged. The air conditioner always runs in the defrost mode of all vehicles. If it is, all is functioning as it should. The problem may simply be too much glass and too much humidity in the air. In those situations, running one of the main units could be necessary for quicker defogging.

Just a sidelight...it is a lot of window. Should you hit any freezing drizzle or freezing rain, the defroster will have a tough time keeping up. Found out the hard way trying to limp into a truck stop and wait it out. Where...you guessed it...once again in West Texas I20. Got to be the worst place for weather and driving RVs in the country.

Thanks for all the insights. We were chugging along in 80 degree weather when we hit the front and temps dropped to about 50 over about 75 miles. I suspect the windshield got cold quicly and the defroster couldn't keep up. When we turned on the gen and the A/C's the humidity dropped quickly and the windshield cleared in a few miles.
