A/C compressor Manuf. Number

If I were the one, I'd I won't bother with the other P/N thing, as long as the compressor configuration and connector position is the same.

Get another compressor from a junkyard, and replace with.

Ensure you or your AC tech uses the right compressor oil for the job, if not you'd have expensive repairs at the end.

After replacing the compressor, use a tightening clip to replace the clip on the water hose. It would also be best to replace that hose to a new one, considering aging must have had its toll on the clip and the water hose, or for preventive reasons, you can also envelope a kind of polythene, that's heat resistant on that water hose connections too.

 

Look up Gates PowerGrip hose clamps for another alternative. They are a pain to remove, I’ve found, but do provide a nice even seal. Make sure it is completely over the underlying nipple so it doesn’t constrict unsupported area of the hose if you do go that route. Good idea to replace the hose if you use them too, as they are difficult too remove. (I still don’t know where to get the special tool that they made for removing them without damaging the hose. I also realize it may be hard to position that clamp removal tool depending on hose/fitting location)....

 

May not be helpful. Sorry!

 

I find that a dealer's parts house will usually help you on part numbers even if you don't buy from them. Sometimes you can get a new part online from another dealer for much less as well but have one of the dealers look up the actual part number you need based on your vin. I agree with the compressor oil concern, don't let just anyone change, vacuum and charge the unit. Probably want to buy some oil from Toyota to be sure.

 

A pair of pinches can be used to grip and remove that clamp.

 

I think “ES27C” is the part number. Do a Google search and you’ll see what I mean...

 

Not sure differences between US version and EU, but this looks like the equivalent site. Here we pay $15.

Okay, I found the wiring for my ‘12 Prius v. I have not figured out the wiring order yet, but as a start, let’s match up the colors:

G(reen)
Y(ellow)
R(ed)
W(hite)
V(iolet)
W-B white with black stripe

 

Do they match up? At least 5 of them I hope, better if all 6....

 

Okay, we are almost there. I am still learning how to read the wiring diagram. Can you confirm that I have the correct wire colors while I do this?

 

And this plugs directly into the compressor?

 

Okay. I believe:

1 G
2 Y
3 R
4 W
5 W-B
6 V

 

The other connector:

1 O-W
2 O-B

O(range)
W(hite)
B(lack)
