When I get a chance, I'll have to look up J30. Too much current is a major clue. My first thought was bad fan, but it seems you've replaced it already.
A condenser can't "short out". There's nothing electrical about it. It might be plugged which could create some fun. But a blown fuse wouldn't be one of them. "Jet mode" does suggest the A/C pressure has gone sky-high.My gut is telling me that the AC condenser is bad and is shorting out the system. When in idle it feels like the compressor is engaging and then the car shakes a bit and can hear the fan blowing real loud like a get engine for a few seconds.
That's happened to a few people. Not common, but it's happened.So took it into the shop today and they said the pressure switch is needing to be replaced. It's causing the fan to go on and off instead of running consistently to keep engine cool.
It would place maximum stress on the fuse, but it shouldn't cause the fuse to blow. You might verify it's the right sized fuse.He is thinking when the fan kicks on hard like that its causing the fuse to blow.
The sparkplugs can work themselves loose. Usually the clue is a "chirp" or "click" from the gasses escaping combustion. But the proof is in the fix.He also said one of the spark plug wires were loose making the car run a bit rough.
