Hey all first post here and of course its a question

Well i have an 05 Escalade and the blower motor well is not blowing
I checked the fuse and nothing.When I'm driving around 40 mph I can feel a little breeze coming out COLD. The rear blower works fine.I was leaning towards it being the blower motor relay but I don't know. The bad thing is I don't know were this switch is located so I can't test it or replace it for that matter.
Any help would be greatly appreciated.

Here is the link for the relay
