Heater Blower Motor Replacement…HELP!!

[74MarkIV]

I’m new to this forum and this is my first post…please help.
My son has a 1974 Lincoln Mark IV. The heater blower motor just went out. I have a new one, but can not find out how to get to it. Nothing on YouTube and I purchased some information directions from a site on the web, that proved not to be useful to me at all…can anyone help? And if so, do you have any simple diagrams?
Thanks
Jeff

Pull the glove compartment out. Also look. For the post on blower motor wiring . I thought I needed a new motor but this post advised that wiring connections become loose. Fixed mine today by simply pushing wires back into connection
