Hi, Harry: Just a brief review of current flow from the fuse to the blower. There is a combination of switches starting at the A/C pushbuttons. The pushbuttons switch on-off power to the speed switch on the temperature control lever. Speed control is accomplished by pulling the handle on the lever outward for faster or pushing it back in for slower. Any button other than OFF will send current flow to the switch. I’d suggest verifying +12VDC from the outlet of the HEAT/A/C fuse to the outlet of the pushbutton switch and to the outlet of the speed switch before pulling a good blower.
