Just for info, when I've encountered problems with A/C with similar symptoms - works fine for a while (30-45 minutes) then stops working, it's been because the clutch gap for the compressor has worn to a distance beyond tolerances - and when the under bonnet area gets properly heat-sinked and truly warm, the electro-magnetic clutch actuation doesn't have sufficient oomph to bridge the gap - hence warm air 'til everything cools down.On a 07 Rondo with a 2.6 does anyone know the location of the coolent temp switch. I feel mine needs to be rplaced due to an a/c problem. It shuts down after about 30-45 mins and blows hot air. It cools down for about 1-2 hrs and it runs fine for about 45 mins.
Well assuming it is this problem, it is something detectable.I thank you for your input. Is there any work aroud for this problem without replacing the compressor?
