2008 Mariner - No Heat!

Hi Everyone,

Tried searching the web but wanted to run by you guys before going out and just buying parts to change out.

GF's 2008 Mercury Mariner isn't pushing any air from the vents, putting hand against one and you can feel a tiny bit of heat. Rear defroster still works I believe. Felt the lines going into the heater core and felt hot. Checked fuses and didn't see any blown.

Since no setting produces any pushing air makes me believe its not the blower motor resister in the passenger dash, believe air should still move on high correct?

Coolant levels seem to be fine.

Gotta be the blower motor right? How big of a job is this to change out. Is it common for these to fail?

Any help is appreciated. :hy:
