91 chevy1500 2wd stepside 4.3 5 speed a/c fan problem.
Just repaired a/c and never depended on the fan as much before . defroster in the morning . Now when I'm on the interstate mostly ,with the a/c fan on med. with the recirculate on , the fan shuts down till I stop shut the truck off cool a moment start back up and every thing works correctly ,all 3 speeds work . does not happen if I take recirculate off . Is it a weak fan ?
