I did not say seized, I said seizing up. They can make a squeal and still be turning, but at some point soon they are going to stop completely. I can virtually guarantee that one of those pulleys is getting ready to quit completely -or- one of the other belts needs adjusting.
Also, sometimes, in order to get the belts tight enough, you have to use a pry bar or something along those lines on the adjustable pulley in order to get the belt tight enough to not squeal. Otherwise the belt will slip and squeal.
And just a FYI, WD40 has the nasty habit of causing belts to wear prematurely. It is really just not good for them. In the future, get some belt dressing at the parts shop.
