I have a 2008 JK. A little while back the AC blower stopped blowing. I checked a lot of the components in the center stack - control knobs and such and found nothing wrong. when I went to look at the HVAC blower the plug that provides it with power was burnt from arcing. Ive had this happen on a chevy too. In hot climates (this jeep has lived 100% in Florida and Georgia) people use max AC a lot and the current through the motor is high. All it takes is a little looseness and arcing and it gets hots and spirals down till it quits. I needed a new connector but Googling kept coming up with other connectors - resistors and stuff from other models with different designs. Finally I struck gold. Searching for the 2008 Jeep kept coming up with all manner of expensive OEM pigtails some of which didnt look right. But eventually I discovered that the toyota Tacoma from 2005 to 2016 uses the exact same connector. Pigtails for that cost $10 all over ebay and amazon. Presumably they have the same problem? why else would the aftermarket be flooded with these connectors?

anyway it fits. Its working, all is right with the world. I wanted to make a thread for this just so it would show up for other people on a google search and with a photo so people could see what connector I was talking about.
Its the one that plugs directly into the blower motor housing under the passenger side (under the glove box)

Left is the original all burnt on one terminal, the right is the (toyota) replacement.

If you want to find the same part, google search for either of the following (or both) toyota part numbers. It should also serve as a reminder (for brand snobs out there) that in the last 20 years car companies are often buying the same parts from the same suppliers

82998-12380
90980-10916

 

How do you take the burned pigtail off the wires so i can put new pigtail?

I am in the process of performing this repair. I have found that My Local Toyota Dealer keeps these parts in stock. I also found that neither of these part numbers is a complete pigtail.

82998-12380 = this part Number is just for the wire that goes inside the housing. it comes with the correct end but you will need to buy 2 of these from the dealer.

90980-10916 = this part Number is for the Housing (the plastic part that's melted) you should only need one of these.

Putting these together should be relatively simple. Just slide the wires in from the back side of the connector. They WON'T be Color coded so you'll need to reference your old burnt connector for which wire goes where. If you connect them backwards the fan will still spin, but in reverse and you won't have as much airflow.
