Blower fan issue 04 F 550
I'll start by saying a/c compressor is new, blower fan bench test good, a/c defrost system was operating fine. 5 days ago couldn't control air vents, easy fix, vacuum pump failed, replaced problem fixed. 2 days later turn on a/c no fan at all and a/c comp. not kicking in. Fuse and relay good, no power to fan under hood. Pulled resistor was scummy but ohm'd like it was ok. Is there another fuse ? Or should i be looking at dash fan switch control ? Tks.
