Dorman Radiator Fan Assembly 621-071 - Read Reviews on Dorman #621-071Alright so the pigtail on my ac control system is burnt out and no one seems to be able to figure out what part it is for me to buy a replacement it connects to the radiator assembly but I'm not sure where it goes to after that. The link above has a good picture of the pigtail female that the plug I need plugs into.

 

You can take the pigtail with you to a parts store or dealer and see if they can match it. You can go to a junk yard and see if you can match it. Other cars or trucks probably have the same pigtail. You can hard wire the wires or get any kind of plug and use that.

 

GM stuff is common, notice the orange color, there are going to be other connectors that will work. I had that issue with a 2 pin crank sensor, replaced it with a cam shaft sensor connector since autozone didn't have that one. You might check a MAF sensor connector part.
