2001 Dakota heater blower/resistor problem

I don't know how many people on here still own older Dakotas, but if you do, you're probably well aware of the problem with burned up blower resistors. I've put 3 resistors, 2 pigtails and 2 blower motors in my truck and as of last week, my blower completely stopped working. I read a lot about this, and I've found 3 possible causes: bad ground straps, bad ignition switch, and poor quality replacement blowers. I'm also wondering if a small heater core leak can cause it? My last resistor lasted about 6 months, and I only used it on high for short periods and never used the AC. The consensus is it's caused by high amp draw by the blower. Does anyone have a diagnosis/repair pathway to help me get to the bottom of this problem? It would be great to have a comprehensive answer that covers all 4 possible causes.

trace wires and check all connections as state before must likely some type of short/ high resistance somewhere, troubleshoot splitting circuit from fuse/ components to isolate
resistor should be under glove box area think two or three screws on a plastic piece when looking up from carpet area bellow it. hard to reach small screws and plastic piece (heating duct for floor?) and the two screws on heating resistor. Only had to replace it once, 2001 purchased in 2003 still going strong
