E9X BLOWER MOTOR WIRING DIY FIX

Summary

A step by step on how to fix your blower motor wiring to prevent a fire in your glove box.

Part numbers:
  • Blower Motor Resistor: 64119265892 You can find this on Amazon or EBay($60) for much cheaper than the dealer($120). Up to you how much you want to spend.
  • Connector: 61136925196 You can get this online or at the dealer parts department. Cost me $1.50 at dealer
  • Double Leaf Spring contacts: 61138377730 You can get this online or at the dealer parts department. Also cost me $1.50 each at dealer. I bought 5 just in case I messed one or two up when trying to crimp them on. This is for the small wire
  • Double Leaf Spring contacts: 61138377732 You can get this online or at the dealer parts department. Also cost me $1.50 each at dealer. I bought 5 just in case I messed one or two up when trying to crimp them on. This is for the bigger gage wires.
  • Wire: I went to AutoZone and bought some thicker gage multi strand copper wiring. I think a 5ft roll was like $5.
  • Electrical butt connectors or you can just solder the splice together. Soldering would be the most effective for not getting loose and would generate less heat in the future.

Tools:
  • Torx T20 and T15 I believe. Cant remember exactly.
  • Good set of wire cutters, wire stripper and connector crimpers. Usually an all in one tool.
  • Some heat shrink to cover the splice.
  • Soldering gun and solder.

    Excellent content and write up JazRedGT. One clarification...have you seen some of the posts on the N5x FB group showing the fix also including moving the grounding location off the connector itself and to one of the nearby exiting chassis grounds? (Question for anyone really at this point)

    Thanks for this. Didn't actually go through and do it, but I did check last night and everything looked fine to me on mine.
