Blower motor resistor repair

If your blower only works on high it may be the resistor pack which is accessed from under the hood on top of the blower motor assembly. The thermal fuse goes bad. I found them on line cheap and took some pictures for reference. Taking out the old one is hard. I used a hardened pick to open up the crimped part. Here’s the pictures:

Just don't try to solder the new thermal fuse in, soldering may ruin it!
