buickbrothers Posted January 24, 2023 Share Posted January 24, 2023 Ok gents. Dash is in and most of the wiring is done, but I have a few issues which I will ask about in a different post. My car had factory AC. The 55 Shop manual does have a diagram on the AC control wiring. However, I quickly discovered it is different from what my car has since it was missing a 14 gauge white wire that I had, and it is not referenced in the diagram. I've attached both diagrams in case someone else has the same challenges. 55 Shop Manual AC Controls: Research - Fisher Body Service News Booklet (AC Controls): Link to comment Share on other sites More sharing options...

buickbrothers Posted January 24, 2023 Author Share Posted January 24, 2023 Are they both showing in this one? Link to comment Share on other sites More sharing options...
old-tank Posted January 24, 2023 Share Posted January 24, 2023 The one without the white wire going to the middle of the resistor is for 54 Buick, which has 2 speed fan vs 3 speed fan for 55? 1 1 Link to comment Share on other sites More sharing options...
buickbrothers Posted January 24, 2023 Author Share Posted January 24, 2023 Here's the sources of each diagram. The one without the white wire is in the 1955 Buick Shop Manual. I found the one with the white wire in a Fisher Body Service News Booklet at Hometown Buick site. As you can see in each screen shot, they are both labeled 1955. The Fisher publication indicated it was a correction to the Shop Manual. So you are probably spot on that they published the 1954 AC control diagram in the 1955 Shop Manual and then corrected it with the Fisher Service News update. See if you have any thoughts on my other post about the 1955 Roadmaster Model 72 Power Window/Power Seats wiring. These are my last wiring items to sort out and validate I'm getting it done correctly. Thank's as always Old-Tank. Link to comment Share on other sites More sharing options...

buickbrothers Posted January 24, 2023 Author Share Posted January 24, 2023 Are you asking do I have a "Private Message" account? Is that a feature in this forum as I can't seem to find that option. I'm set up to follow your postings btw. Link to comment Share on other sites More sharing options...
