My car was jumped incorrectly. The car seems to operate just fine, but the fan does not blow. When the ac or heat is turned on (to any level), nothing seems to be blowing out of the vents. The fuses were checked visually and several replaced. One of the fusible links was removed and replaced (one of…

I would have never known about this connection, thank you! Back probed the connector at AF4 and received a reading. [IMG_4266]

I believe that both wires have 12 volts. Connect the black lead to body ground and check the blue wire again. By the negative 12.66 shown on the meter it appears that there is no power on the blue wire, seems like there is a problem in the fuse box. Do you have 12 volts on the stud in the fuse box? …

After looking at the wiring diagram and the last picture I am wondering if the connector the meter probes are connected to is really connector AF3, since the diagram shows blue and black wires in that connector. Am I looking at this correctly? If that is correct then you need to check for power on t…

You are right. So the black lead is reading 12 volts, the post in the fuse box is reading 12 v, and the blue is reading nothing.

Hopefully you have checked out my previous post.

You will have to remove the fuse assembly and check the connections below.

Okay, that is good. I now suggest you check the power going to the blower from the 50A heater fuse and verify that 12 volts is getting to the blower. You may have to back probe the connection on the module for the blower.

oomph, the entire fuse assembly? What connections below will I be testing?

Yes, this was already done, there is not 12 volts getting to the blower. Also, in the picture I am back probing (incorrectly) the connection at AF3. The AF4 connection is the one that clips into the blower fan (which was back probed to verify that it is not receiving power).

There are windows in the fusible link (fuse module) and all the fuses look good. This fusible link has been replaced, but after replacement of the fusible link the blower fan was still not functional.
