Nissan Repair: A/C PRESSURE SWITCH CONNECTOR, nissan frontier crew cab, frontier crew cab

Question
I have a 2002 Nissan Frontier Crew Cab V-6. My A/C has been having problems where no cold air is blowing out. A mechanic friend took a look at it to see whats going on and he said the problem was minor, I need to buy a pigtail or an A/C Pressure Switch Connector. I saw the part its only a small part. My question is do I go to the dealership to buy this part? It seems that the local Autozone in my area does not have any idea what I'm talking about. Your advise would be greatly appreciated. Thanks!

Answer
Jon,

The dealer would know what you want.  Also, a wrecking yard will save you money if they will let you go out and source the part you need.  A parts store is not going to have a clue.  rockauto.com or courtesyparts.com are both good options if you can get a listing.
