Today I was running errands and when I started my 2014 Raptor I heard a low pitch squeal (probably the belt) but it quit and upon restarting it did not do it again. Then I noticed the AC was no longer blowing cold. On my next stop I popped the hood and saw where some grease has come from the AC clutch and been slung around. Has anybody seen this? Is it likely just the clutch? Any ideas on cost to fix? Is it ok to drive?
