My wife’s 2017 Limited has no front AC - nothing comes on, not even the blower. The back AC unit still works? This happened a few months back and I replaced the compressor relay and the AC began working again. When I bought the last relay, they came as a pair so I tried putting the other new one in and nothing changes this time.
Any ideas out there? It seems impossible to get her expedition into a local shop within the next two weeks.

Have you had the safety recall done, which replaces the front HVAC blower motor assembly?

There is a wiring pigtail TSB for the connectors, unrelated to the safety recall: https://static.nhtsa.gov/odi/tsbs/2019/MC-10163573-0001.pdf

Thank you all for your help with my AC blower motor! There is a large back order on the pigtail right now, but hopefully I’ll get to it before the super hot weather gets here!

My local mechanic replaced the blower motor (wife couldn’t wait for Ford Service on 6/15). Worked great…for 2 days. Now it’s intermittent

Take it back to the shop you had replace it and tell them to do it right this time.

Took it back & they found a bad regulator. Replaced it and the same situation occurred: good for 2 weeks, then intermittent, now not blowing at all. Goes back to mechanic on 7/5
