2006 Silverado - blower problem

I have a 2006 silverado wt 4wd. the blower motor quit working so I went and got a new resistor. put the new resistor in and it didn't help. while putting the new resistor in I noticed a burned wire in the 7 pin plug in for the resistor. replaced the wire and it works ,, if you pull forward on the pigtail, or push back on the pigtail does the same thing with the old or new resistor. when I say push back or pull forward on the pigtail, I mean slightly with your finger. what would you replace next? thanks

If you are describing a problem with a pin in the plug then you replace the 7 pin plug assy.

There shouldn't be any factory splices to that plug.
If you are describing a problem at what could be a splice.... maybe that plug had been previously replaced.

Bought that part from autozone and it did the same thing. Leaning towards bad connection in pigtail

You said you only replaced a wire on the pigtail.
As said, the pigtail likely has more damage or loose connectors and replacing it may fix your problem.

you are right I only replaced one wire in the pigtail. I noticed that that specific pigtail is available just about everywhere;. so I assume there must be a reason why it is. will have to try that now, the problem is where to buy it. prices range from 216. from gm dealer to 6.95 on ebay. the problem with the ones from ebay is there are only two colors of wire, black and white , but I would kind of like to stay with the factory color code.

Frank, Just to be clear, You said you push/pull on the pigtail after replacing the one bad wire & the issue is still there. My question is, are you securing the wire while pushing/pulling on the pigtail assy? I'm wondering if the problem might be on the other end of the wire. Did you replace the entire wire, or cut and splice the original wire?
My point is, when you're pushing & pulling on the pigtail, you could be pushing & pulling on the wire itself &if the problem is really at the other end of the original wire, replacing the whole wire or even the whole harness might fix your problem.

Push & pull on the wire itself & see if its still creating the problem. That might tell you whether to replace the wire, harness or the pigtail.

The pins and sockets in a connector have some mechanical means to prevent the pin and/or socket from moving axially when engaging the 2 halves of the connector. Pull on the wire attached to either pin or socket to insure it is captured. If it is not, trying to find a replacement pin/socket/connector half is almost impossible. Only thing left is to splice in a new connector. As a temporary fix, you should be able to push offending pin/ socket back into its half with the connector engaged. Tape it to something so it can't pull out. Hope this helps.

I separated the wires and while the fan was blowing moved each wire individually. one of the wires you could hear spark, so I am going to replace the harness or pigtail whichever is availabe. thanks for the help.

With use and from the heat.... the contact pins loosen.
It would be best to change the entire 7 pin connector.

just an update. ordered the connector from ebay and it came arrived, paid about 10 dollars for it and it fit alright, but the wire gauge was way off. wires were about 18 gauge. went to autozone and got the same part and the wires were 12 gauge. used the autozone part as the original wires were lots heavier than the ebay part. so it goes to show that cheaper isn't always better. the autozone part was about 3 times as expensive, but much better than changing it out every year due to poor quality.

These blower connections have to pass about 20A at top speed so the connector has to be top-notch.
You can use skinny wire for a short distance as long as the voltage drop along the wire is a small percentage of the 12v to 14v you have to work with.

Problem was fixed. More suggestions are useless.
