[QUOTE="machoheadgames, post: 429835, member: 18789"] Pretty certain that is the connector for factory air conditioning hookup and isn't related to the heater blower at all. what other wire colors are in there? I believe it is connector C213. the dark green wires should go to your heater blower "on" switch which is a simple push button switch with a terminal on each end. It is normally closed at rest but the HVAC mechanism holds it open to cut the motor off. When you choose defrost or heat, the lever lets go of the switch's button and it operates. The current goes from there to the low-medium-high switch which then shoots the current over to the blower motor resistor to resist it properly before the motor sees the power. If you choose high, then the current basically bypasses the resistor and the motor runs at full speed. So when you said " I reconnected the wire for my blower switch plug and my blower motor now works. If I reconnect the second DK Green wire that runs to this connector it blows the 25 Amp fuse in the #12 slot on the inside fuse box.", I got lost and was no longer sure what you mean. Dark green wires run to the connector in the picture? The plug in your picture should be AC only, not heater, so I don't think you should be touching that plug at all. Edit: scratch what I said about dark green wires in the paragraph above^, i see them in the pinout for that C213 connector in the PDF I attached. I'm not sure what they do but they are definitely not for the heater because they are for AC only. I'll see if I can find what those two are for. One should be 14Ga and one 18, no? [/QUOTE]
