Heater restore and fan switch
 

This is the heater that was in my truck when i bought it years ago. It is the "Firestone" model from what i understand. The core has very small leak when i tested it with 10 lbs of air pressure so i'm going to take it to the radiator shop and see if they can clean it and fix any leaks for a reasonable price. The heat/defrost cable works fine and i'll thread the end and put a new knob on since the old one is pretty much disintegrated. The one question i have is where can i find a 6V switch for the fan? It was completely missing (just a bare wire going to the fan is all that remains). I test the fan on my 6V battery and it runs nice so i think i'll just need the switch but i can't find any repops. I'm not sure if there's just one speed or if it's rheostat type thing either? Any ideas?

Would the 2 speed switch from a stock heater work? Like this type here.

Abe i think so. That's kind of the setup i have now (one for fan, one for defrost)
I found a Borg Warner S180 6V switch for a couple dollars that i'm going to try out. My friend owns a NAPA and thinks he has some NORS switches for 6V that will work. I need to find out if the core is repairable first before i spend any time or money on this one. I think i'll drop that off today and see what i find out.

Where do you take your cores?

I open for suggestions but the place that i'm aware of that still does them is up lycoming creek road, union auto. There is a place called the radiator shop in williamsport but i've never been there

There is a guy in Mill Hall his name is Jeff Weaver. He has a radiator repair and garage. He is good and cheap. He is on Peale Ave by the bridge. Number is 726.3870, cell 6607595.

Do you have the license plate that matches the DAV key chain?

Nope. That would be cool.
