I changed the blower motor, Now the brakes pulse when the blower is on high. Why?
I had the blower motor changed and it seemed to work fine. But I have found that when the blower is on high, and I step on the brake there is a pulsing that almost feels like the brakes are going metal to metal.
When the blower is on any of the lower speeds there is no problem, but the brakes start to pulse as soon as I turn it onto high.
Any ideas??

Pulsing might be the wrong term, it's not like the anti locks have came on. It's more like the brakes are at the point of going metal to metal.
This started as soon as the motor was replaced and only happens when the blower is at it's highest setting.
I would think there is no conection.
A pulse in brakes is normal at times. all it means is your ABS system has been activated.
When it pulses are you braking harder ? What is the road condition?
If both are normal then I would have to say maybe an electrical short somewhere that is activating abs when they are not needed.
When your blower motor was installed something was hooked up wrong and it is drawing power from ABS when blower isn't onhigh it isn't drawing enough power.
If it is only acting up when blower is on that is more then likely the problem. Get it fixed fast before you mess up the computer
