Dear mid-60s Buick parts-hounds,
Old Air Products claims to have a reproduction of the heater blower switch for our 1964-66 Buick A-bodies. It is listed on eBay at the moment:
https://www.ebay.com/itm/204605025451 (https://www.ebay.com/itm/204605025451)
Does anybody know if this reproduction actually fits? The switch on Biquette is a little loose. Right now it isn't really a problem, but I would be curious to know if a replacement is easy to come by.
Thanks,
Edouard

It does look correct. As noted in the eBay listing, it is for non-AC system.
I have a few of these that I have re-conditioned, by disassembling, cleaning the internal contacts, applying new contact grease and re-assembling. It is important that this switch works properly, as I have seen the main power wire melted from the switch being bad.

I think that would be the wiser move. The original switches have literally lasted decades whereas a lot of aftermarket pieces are made of inferior materials. This particular switch is prone to overheating from poor connections or weak fan motor. I would definitely rather have a rebuilt original. It probably would be a good idea to check the amperage draw from the fan if your original switch has to be replaced.

Thank Loren and Dan for your replies,
I hadn't thought about these switches needing to be quite so robust. It is a good point. At the moment Biquette's switch is simply a little loose, so it was mostly as noted a curiosity question. The reproduction switch might be okay in Biquette's case because it is simply controlling the Vintage Air system and therefore most likely is carrying very little current. I assume all that switch is now doing is sending signals to an electronic controller board.
Nonetheless it is not a bridge I have to cross yet, so I'll simply keep this information in my mental filing cabinet.
