Can you feel a decent flow of air coming out of the vents? If so, a stronger fan won't give you much. If not, check the heater hose connections before you start worrying about the fan itself.
Is the air coming out of the vents decently warm? If not, the heater valve may not be properly open, or a heater hose might be blocked, or the heater matrix may be clogged up. Using a cooling system flush might help. There may be water trapped in the heater box, so the air you're blowing at the screen is already damp. There's a pipe coming out of the bottom of the heater box that terminates in a rubber bulb with a slit in it, that's supposed to let out rainwater that gets into the heater box, but if the bulb gets clogged with detritus then you might get water building up in the heater box. You can buy glass treatement products that are supposed to resist fogging - I have no idea how effective they are. That should give you a few avenues to check out before you start throwing money at the problem!
