Electrical problem
1994 Ford Explorer 6 cyl Two Wheel Drive Automatic

My blower motor quit working. I keep blowing replay's under the hood and it has actually burned the plastic where it goes in the fuse box. I can put a new relay in and it will run about 15 minutes and then burn up again. What could be causing this problem?

the relay is power by the fuse # 5 in the power distribution box, remove the fuse and check for corrosion. check the rating on it . if the plastic is burn, or cause relay contact to contact each other, change the plastic. Check for high resistance in the blower motor. (sending the diagram in your email)
