Thread: Heat stake in blower motor resistor

I supposed I just use a chisel to break the head of the rivet off and the resistor would come off. I did that and the resistor come off. For new resistor, the manual says I have to use screws to attach the new one. I went to AutoZone and bought a new one. It works but it has a different pattern of holes. It seems the broken rivet now is in the way that the new resistor does not fit flush with the mount. Am I doing the rivet removing wrong? Or I just have to get exactly the same hole pattern in the new resistor to make it work? All the parts in local auto store has the same pattern. Even the AC Delco ones I saw on eBay have the same pattern that would not fit directly. Is there any way to deal with the remaining of the rivets so the new one will fit?

The old one looks like this. The remaining of the rivet can come through the larger hole.

The new ones all look like this. The rivet cannot go through so the resistor does not fit flush with the mount.

Just want to post an update. I have the parts from advanced auto parts, the pattern of the holes is different from the original one. But the remaining of the plastic rivets sit in the hole. Therefore, the resister will sit flush And form a good seal. You just have to line it carefully.

Also, The resister I bought does not come with new screws. #6 self tapping screws are what do you want to attach the new resister.

Good deal.

The one I bought does not come with screws. It is also BWD but anyway, it is pretty easy to get those screws.

Thanks a lot for your suggestions and help!
