GF's 99 escort: Turning on the heater keeps blowing the wiper fuse. Both work fine until fuse blows then no wipers and no blower motor at any selected speed. Problem comes and goes. I am not familiar with Fords and there are a lot of relays, switches and grounds to check. Any idea where to start? Thanks!

You might find a free manual here: http://bit.ly/autozone_repair_info or go to http://bit.ly/alldata_repair_manuals or http://bit.ly/mitchell_repair_manuals_online and get an online repair manual subscription.
My initial thought is that the blower motor may be going bad and causing the fuse to blow. Has the motor be abnormally noisy?

Actually when the heater works and you turn it on you can hear what sounds like a delayed compressed air sound and the motor sounds whiny. Is there any way to test the draw on the motor (I have a tester)? My GF doesn't have a lot of $$$ so I don't want to replace unless I know I need to. THANKS!!!

What is the amperage rating on the fuse for the motor? The meter should be rated near that. Normally 10 amps is OK.

They both are wired into the same relay,Driver's side under dash on a big white relay box. I am working on a blower issue myself and am trying to figure out how to get that relay box down. I would guess that is what is causing it as that is what they have in common-just a guess from my own research.
