My 1994 940 Wagon is producing 12v to the heater blower motor on all dial settings 1-5, but the fan doesn't spin. I have tried another motor to no avail. Any suggestions?

Have you checked your ground to the motor? Are you shure the Test motor was a good motor?

Thanks for your post V70. I double-checked the fan by connecting straight to the battery and it spun strongly. Once I did that, I hooked it up to the fan plug and it worked fine on all five settings. I did play with the ground, but I think the new fan just needed a strong jolt.
