05 MPV Loud Fan Noice when A/C turned on
I have a 05 MPV that makes a extremely loud noise like the radiator fans are running at full capacity. This happens even when the engine is cold. Switch on the A/C and the dual radiator fans sounds like they are going to fly out of the front of the van. When the A/C is off the fans appear to be working as they are suppose to be.
I know that the fans speed up when the A/C is on but these seem to be at full capacity. Got any ideas? Thanks in advance... Steve |
fan trouble
My 04 MPV radiator fans are on high almost all the time. Even when I turn off the van they keep going on high. I have to turn the key on and then off again and the fans will turn off. I have no idea what's going on but would appreciate some insight into how these fans work. Sorry that I'm no help.

It sounds suspiciously like a sticky relay, the relays are in the engine compartment fusebox, and what each does is indicated on the underside of the fusebox cover.
The other cause for this can be the engine temp. sensor, also you may need the cooling system cleaned up (flushed plus clean bugs etc. out the rad. fins). Rare but not impossible is the "snake thing" (the A/C temp. sensor running down the rad, may have come unglued from the rad. |
Thank you so much for taking the time to reply to this. I will look at everything you suggested and I feel sure you hit it. Again, Thank You!!! Steve
