Cooling Fan fuses are blowing 2000 MPV

I own a 2000 MPV 2.5. I had both fans replaced three months ago but since then periodically both fuses for the cooling fans blow out. The mechanic changed the fuses from 30 amps to 40 but last night the 40 amp fuses blew, the car heated up and we had it towed back. The wiring looks OK from what I can see. The fuses appear to blow when there is a lot of strain on the engine, i.e., hot weather, long trip. So could it be that I have a problem with the cooling system which is putting a big strain on the fans? Plugged radiator, bad thermostat, air lock??? Also I noticed that there are two arrays of what I assume are relays for the fans under the hood, one next to the fuse box, the other on the passenger side. Both have two large black boxes (coil inside) and a green one. Could these be a problem? Any thoughts people? Thanks

you should never ever put a wrong rated fuse...find a new mechanic...you lucky your car didn't catch on fire yet...also check your fan relays

On our 2001 MPV the wire leading into into the fan motor shorted out you can see burnt wires.
