My 2011 EXL V6 Coupe recently has an intermittent problem with the cooling fan dropping out when the A/C has been on for a while. The fans operate normally without A/C being turned on. The fan dropout causes the coolant temp to go up and the A/C stops cooling, but, the A/C fan is still blowing hot air. I know the wiring for the fans is complex and I don't have the wiring diagram. Any idea what is causing the problem??
