Does anyone have a pic of a blower motor switch for a 53 f100. I can't find one in the boxes of parts I have and the web search comes up with alot of variations not sure what is correct .

 

According to my part listings, it should be 1C-18758-A. I have seen two variations and I'm not sure which or if both is/are correct. They all have three bullet terminals, but the variation is with the middle terminal that is either parallel or perpendicular to the actuation shaft. Of course, there are also many after market heaters that dealers could have installed, or installed later along the way that don't line up with the Ford parts listings.

 

There is one on ebay for sale.

I think that is for a 55 and up. Mine shouldn't have the bracket.

 

54-56 look the same with a couple of differences. The recirculating heaters have 2 *****, blower and defrost. The fresh air heaters have 4. The other two are temp and ..... I forget the 4th ****. I just got it... and I didn't Google it. It is Air.

Also, on the 54 blower switch the first click is high fan, when pulled the whole way out it is on low. On the 55 blower switch, the first notch is low, all the way out is high, which makes more sense to me. I don't know how the 56 switch is set up.
