A/C wiring pin bent and now hybrid warning light plus no A/C

Hope it's not the ECU....... : ( Have you tried it with it unplugged

 

This is black wiring going into the compressor, the 12 volt wiring? The connection (atop the compressor) has been problematic in past. If the engine bay's been pressure washed or hosed down in anyway, that connector can be a little cup holding water, corroding.

 

Exactly!

This is what I posted in another thread on the AC compressor supplied on Prius models.

There is, however, one "Achille's Heel" with the AC compressor. It's the connector pins that corrode. When this happens, the entire electrical compressor is useless.

Contrary to what some advocates say about dielectric grease, I fill both the AC compressor and water pump connectors with it. It keeps water vapor out of the connection. Pressure of the contact between the connectors displace the grease and make good contact, even though the grease is non conductive

 

That compressor is variable speed and runs on high ac voltage from the inverter. Generally a pin that is just a little too short may not connect. It has to be pulled back or replaced. Then the codes need to be cleared. You may have voltage leakage as well which will cause a hybrid code. Really need to get that connector back to original or go to a salvage yard and get a new cable.

 

Someone's been down this road before, and IIRC was not able to repair the pin connection atop the AC compressor. Again, it is the black, 12 volt connector we're talking about? Not the orange (high voltage) one?

 

That mighta been the outcome in previous case, sadly. Part of the problem was Toyota doesn't offer just that pin connection as a "part". Maybe just buy a salvage compressor?

Check with a dealership service dept first, cus this apparently does happen from time to time.

Again, culprit is poor design plus pressure washing.

 

Thanks Toyota.....................

 

Honestly, that connector is part of the compressor. Even if it were sold separately (I mean, what car maker does sell component parts of their A/C compressors?), there'd be no replacing it without disassembling the compressor, and who does that?

I mean, if the compressor gets replaced and goes into the rebuilt parts stream, and the rebuilder finds nothing else wrong with it, that's probably where it gets fixed. The rebuilder will have the parts and setup for doing that.

The local auto electric specialty shop near me has rebuilt starters and alternators for me on site before. Rather than swapping in some no-name rebuilt from autozone or the like, I've left these guys my original equipment alternator or starter and picked it up later made like new. They have everything needed in back, takes them maybe 20 minutes once they get to it. I don't know if they also do A/C compressors. If there's a shop like that nearby, might be worth asking.

Leaving that low-voltage connector unplugged won't hurt anything, you just won't have A/C.

 

This can't be correct.....?

New aftermarket with all the fixin's?

 

Even the photo is wrong. There are no drive pulleys on the Gen 3 AC compressor.

Could add some, for a sort of retro look.

 

It'd be nice if, you remove the torx screws (or whatever they are) on that connector, and there's 2~3 inches of wire behind. Enough that you can lift it off. And a replacement connector was available.

Here's remanufactured, through Toyota dealerships, $1486 USD:

Ouch! Or, in the original, German, "Autsch!"

 

Rule #1: fur chrisakes don't spray water in the engine compartment. It's not worth it.

 

I filled the connector on my AC compressor, as well as the connector on the water pump, with di-electric grease to prevent water entrance and corrosion.
