89 560SL A/C blower issue

The wife's chariot isn't blowing A/C. I can feel cold air at the vents when moving but the blower will not come on. Periodically, usually when the outside temps drop (late afternoon & evening) the blower will start working and everything is fine but in the heat of the day, no blower.
Am I looking at the PB switches or one of the ECU's? Is there a method by which I can refurb the PB's?
