GN AC Blower
My AC blower didn't work at all when switched to the HI position. I found a burned out two wire connector between the AC blower unit and the right side hood hindge. The small wire was connected OK inside the connector but the 12 ga. red wire was burned off inside the connector...
Need readable GN wiring schematics
I've got the mirror image of your GN AC problem. My 87 GN's AC works on low and medium but does not work in the high position. If you learn of a 'fix' please email it to me and if I find a 'fix' i let you know.
Have you found any readable GM wiring schematics...
