If I remember right, GMCs of that era have positive ground electrical
systems. I assume that your converted 12 volt system is negative
ground. If so, the permanent magnet original blower motor will turn
backwards.

Subject: [oletrucks] 12 volt conversion question
I am reassembling my 49 GMC and have converted over to 12 volt. Do I
have to change the defroster/heater blower motor and switch or will it
function alright as is ?
And by the way , thanks for all your help over the last five years. I
have been lurking and
have learned a great deal from everyone...
