    Yesterday while driving and trying to figure out why I still keep getting a p2757 code after having my transmission fixed my blower stopped working. I checked the fuses then found this:E0555F6B-7D68-4D03-A199-C76D49A7A477.jpg if I press on the brown wire the motor starts to run again. I’m hoping I can just replace this section but I’m a little scratchy on the electrical stuff. From what I’ve read on here there are multiple connection styles. Can I order this section then just splice it in to the old wiring? It’s kind of a mess under there.89562D08-52F3-4CFD-A6F9-FC4D3A996708.jpg

    Those butt connectors they give you to splice to your wiring work ok IF you have right tool to crimp them.

    Suggest toss out the Butt connectors.

    Solder (rosin core) and heat shrink. Makes a strong connection.

    Yeah, just get the kit. Butt connectors will work fine. Just tuck everything away neatly. It's a bitch to get to, but not horrible. Should take 20 mins max.

    That’s a bit beyond me right now.

    I think it’s Delphi that makes a replacement connector. Going forward, be sure that all connections are tight, a loose connection makes heat! I had one go bad on my ‘06 years back.

    Yes it is Delphi. In fact the entire HVAC system is a General Motors special. I have had to access the GM electrical catalogs to find replacement connectors and terminals for several things related to the HVAC.

    Lots of folks say you absolutely, positively 100% need to solder all connections in a vehicle. But let me ask a simple question: From the factory, how many connectors are soldered on? Answer: Zero. They're all crimped.

    I won't disagree that solder - done correctly - makes a good, strong connection and heat shrink - done correctly - makes for a great insulator. However, the chances of properly soldering and heat shrinking connections under the dash of one's truck are pretty low. Remember, the connection that gets lose and arcs is not the crimped connection to the wire. It's the male and female connectors themselves.

    Agreed. Most shade tree mechs don't have the proper tools to make a good, solid crimp connection. Production lines use pneumatic or hydraulic crimp machines with the proper strip lengths and connectors. Crimping in the production line is quicker than a soldering process. Many cold solder joints get made in production.

    The odds of me correctly soldering anything are pretty much nill.

    That’s because solder changes resistance in the wires

    Gonna need a really, really, really sensitive ohmmeter................

    Then you are implying crimp connectors don't change the resistance. :rofl::rofl::rofl:

    Yup, but so does a crimped connection. And don't even get me started on what a cold solder joint does for resistance. That said, a decent crimped connection beats a lousy soldered connection any day of the week in my book - especially when you're working under the dash.

    I suggest you invest in a pair of pliers similar to these. There are cheaper ones out there that will do the job just fine, but this is the design I use. The butt connectors that come with the part I linked earlier look like the better ones that have a heat shrink insulator. After you crimp it heat it with a big lighter or something and it will shrink down and seal up the connection.

    I meant if you replace crimp with solder vs crimp with crimp. That’s why no auto repair manual under the sun tells you to solder anything

    No... I have to disagree here. A proper soldered connection will not change the resistance in any meaningful way for automotive use.
