Last week my wifes van A/C button on temp control stopped working and when that happened the a/c would no longer come on. So I took it to dodge and they did a check on it and they told me the a/c heater/temp control is no longer good and to replace the part it will cost $395 for the part only. So I called my brother who is a mechanic and he suggested me to look at www.car-part.com it shows used car parts for reasonable prices. I went there and looked and noticed some say Blue or White plug. So I took the unit of of the van and looked. The plug on the back is white and then shows PO4677615AE. On futher looking I also noticed that the same numbers where also showing up for the blue plug. So can I use the blue or white plug?

 

You will need the white plug that matches the one you have. They are different and won't plug in to each other.
