First, I'm sorry. I was thinking 2002 and not 1992. The resister is mounted on the firewall and looks nothing like what you have. I have to ask. The wiring harness that plugs into the resister is known to melt down (usually as a result of a bad blower motor drawing too much power). Are you sure nothing was bad there? Next, remove the resister from the firewall and make sure nothing is shorting against the firewall. Finally, you mentioned that only one speed was working. Was it the high setting only? As far as the part you got, I can't tell what it is too. I would return it to the parts store and ask them to confirm that they got you the correct part. If you wanted the blower motor speed control switch, they messed up.
Let me know. I have been through these systems for years. They are really straight forward. The most common problem is the resister, then the wiring harness plug as I mentioned. Recheck that and make sure nothing has melted through allowing it to short and blow the fuse.
