To last reply --- Do you drive where theres sleet and light snow - or where theres road spray when snow starts melting on roads (when temp is about 32'F). Mine aren't sensitive enough to kick on when truly needed. I would love to love these rain sensers if worked as needed. Maybe mine has issues. I'll see if dealer can replace or set some sensitivity adjustment (if not there should be?).

 

I live in PA, so today is 6-12" of snow... the wiper sensor doesn't do snow as well as it does rain, I guess thats why its a 'rain' sensor? I don't know... it doesn't bother me much, other than snow it does very well...

 

The original RainSense that I had on my 2002 TrailBlazer worked a whole lot better. I was sitting at a stop lite and the car in front sprayed their W/S and there was a small amount of mist that came back and hit my W/S and triggered the wipers. The '07 wasn't anywhere near that good. Not surprised that they deleted it. Wish they had just gone back to the original tho.

 

What you say proves my point - or possibly what GM design team missed. If it don't work consistently with snow falls or light freezing rain or constant road spray - then one has no choice but to put wipers at low speed (which will dry wipe the windshield) or do it manually when needed (which I was doing constantly during particular rains or snow falls). By going back to the normal delayed wipers at least one has better control of the situation. Its to bad GM just didn't include an on/off mode for the rain sensor so the driver could choose dependent on the weather situation. Or at least included a sensitivity control.

 

The sensitivity control is the variable speed portion on the control ****.

 

You're right -- but even at its highest setting mine are not sensitive enough (or at least on most light-rain or sleet/snow situations). I meant to say a "major hidden control" so one can set overall sensitivity. Before I confuse myself anymore let me just say I'm happy to have back the old stand-by delayed wipers (sensor disconnected)

 

Are you saying to unplug the entire wire harness that plugs to the review mirror to disable the rain sensing wipers?
