Getting colder, blower motor not working. Need some help.

I am having problems getting my blower motor to work. I pulled the v6 out in may and put in a LB9.

I think the problem lies with a plug that is not plugged in. In the same area my blower motor plugs in, i have a plug with 2 green, 1 red, and 1 black wire that is not plugged into anything.

Its a rectangular plug, any ideas?

I will put a picture of the plug up later when i can.

Forgot to mention, no power to the plug, and fuse is good.

One more update, when i hooked up my voltmeter to theplug in question, i had 0 volts with the fan switch off, and 12 with it on. So i am assuming that is my problem. But what goes there?

Seems like your voltmeter says the motor's shot.

I shoulda told ya to hook the blower motor up to the battery directly and see if it spins... but I guess you can take the new motor back tho.

Hey 9D1BURD, as far as that connector goes, this is about the only thing that I can find that is in that area.

It connects into a wire harness that goes to the A/C low pressure cycling switch in the side of the accumulator. See the item going into the accumulator just above the time stamp in Dave's picture and to the right of the dust cap on the schraeder valve..
