So I am trying to get my ac to work. I replaced the evap when I replaced the heater core the other week and I just got a new accumulator. I open the box and it has a cap and schrader valve on the top of it. The one on the truck has a connector on it.

My question is this.... Do I have to take the connector off the old one and put it on the new or did they give me the wrong part?

 

i don't know, but does the switch on your old one screw on/off the valve?

 

not sure, but id guess its a part separate from the accumulator so try to take it off the old

 

+1... Assuming you already removed the electrical connector from the old one(green plug), you have to swap the switch itself
