I would like to know where the original switch is mounted on the dash? Can you make the defogger blow hot air??
Thank You

69's came with a rear window defogger? Nice!! How good does it work?

It runs smooth.I installed it yesterday mounts behind the rear seat in the trunk. I'm looking for the original switch and harness.

I would like to know where the original switch is mounted on the dash?

The switch mounts above the cig lighter. I bought my motor,duct,grille off ebay also. just waiting for a switch and harness. Does your rear defroster blow hot air?

Does your rear defroster blow hot air?
It relies solely on ambient temperature, cabin temperature.

thats not good. Does anyone know this part #3949992 its believed to be the rear defogger switch?
thank you

Does anyone know which fuse or wire to splice into for power?

A template came with mine but I don't think I have it anymore. I could take some pics or measurements if that would help you.

I sure hope it blows hot/warm air?! It's mounted in the trunk so there's no warm ambient air there.

I suppose drawing air out of the trunk would still be quite a bit warmer than the cold glass.

True. I guess it is a defogger, not a deicer.

hey thanks for that diagram. i seen a wagon power window switch that looks very similiar to the defogger switch. Is that the same switch just a different bezel?

Good reporting John,

Make sure you mount the switch in the upper position. The diagram showing two switches refers to a power convertible top switch and rear defogger combo.

I have this option factory installed on my car, but it is in storage now and I can't get you a photo.

Thanks Phil, just trying to help out.:)

Not sure about the switches being one in the same, I can check that out Monday.

I did find a vendor on line that may have a rear window defog switch part #3959229. Home_Page (http://www.jrschevyparts.com/) or go directly to parts page "Group_9.000 (http://www.jrschevyparts.com/1969_parts.htm)".

I emailed that vendor unfortunetly he doesnt have it.
thank you

hi everyone,
in my quest for finding a switch for my defogger. i have might found a way to warm up the fan by installing a seat heater element behind it.

Wagon power window switch #4432790, would not be the same as the defog switch #3959229.

I will keep my eye open for a defog switch for you.:yes:

I finally found a switch, thanks for looking out size matters.

:hurray: Good to hear, you are welcome. :thumbsup:
