Need help pretty quick

I just put a new a/c compressor on my 1994 truck. It had a bypass pully on it for a while. I have a plug that I am trying to find where it goes. It is right behind the compressor and the plug is red and light blue.

That looks like the power plug for the A/C compressor.

I thought that too, but I just charged the system and it is running fine. I just dont know what this goes too. A/C is blowing cold.

did you check the air intake system? map sensor, or air heater, somewhere in the ductwork?

NonGoggleGuy · 03-21-2009, 02:24 PM

Isn't the t-stat housing near that area? Could be the temp. sensor.

Is this something that has been unplugged while you've been driving the truck w/o problems?

Checked both.......eveything that I can find, that needs a plug has one. I'll try and get some more pics in a little while.

Ok ....here are some more pics.......I still dont know where this goes. There is another plug simular in a couple of the pics but that one has been there for years. No I have not replaced any of the wiring harness either. Thank again for the responses.

leolkfrm · 03-21-2009, 06:00 PM

um I don't see the pics, where did you put them?

Alan Duke · 03-21-2009, 06:01 PM

OK.....I am not given the option of adding the pics......any advice?
