Blinking AC light nightmare

Title say it all, I had a blinking AC light come on last August and my AC went out. Lurked here in Tacoma world and finally got around to swapping the Compressor Clutch out over the weekend.

Clutch was gunked up with some stuff. New one went on and my AC was working again!

All week I had cold AC until today... Thursday, I flip the AC on and my dash lights up like a Xmas tree. CEL, ABS, BRAKE lights... my fuel gauge is moving up and down, voltmeter is sitting at 12.1 (normally 13.3) windows won't roll down, AC button and blower won't do anything.

I run to an autozone, they pull a code for an ABS wheel speed sensor... doesn't make sense, I check the fuses, IG1 NO.2 is blown. I Swap it, windows work again, all lights are off but CEL.
Try the AC again, it seems to try and do something, but then back the dreaded blinking light.

Get home, clean and inspect my driverside ABS, looks fine to me. Unplug battery, CEL goes away, AC is still blinking.

I just moved to SA, I need AC to survive here... clutch was unfortunately not the root source of the problem (sincerely hope I never have to touch a pair of snap ring pliers again...) what else should I be looking at here? The Compressor?

 

Here is the old clutch next to the new one. Was gummed up with the stuff shown in the photo and shaking as it spun before.

 

Being turning your A/C on blew the IG1 No 2 fuse suggest's to me that the compressor clutch coil or wire going to it may have shorted.

Does the compressor turn on for a few seconds and then turn off with a flashing A/C light?

The flashing A/C light is when the A/C amplifier does not detect a speed signal from the compressor lock sensor after commanding the MG CLT relay on.
Possible causes are:
Open or shorted wire(s) in the lock sensor circuit
Bad lock sensor
Internal problem in the compressor
Open or shorted wire(s) to the MG CLT relay
Open in the wire from the MG CLT relay to the compressor
Failed compressor clutch
Belt slipping
Failed A/C amplifier

You will need to check your wiring
The MG CLT relay should have power on pins 2 and 5 when the ignition switch is on, the A/C amplifier grounds pin 1 to turn it on.
You can momentarily jump pins 3 and 5 of the relay to see if the clutch engages, if it doesn't then you need to check to see if your getting power to the compressor on Pin 1 (Violet)
Also check the wiring between the lock sensor and A/C amplifier.
The sensor signal itself can only be effectively checked with an oscilloscope.

 

Blower works fine, as soon as I hit the AC button it sounds like the Compressor is turning on and ramping up to do something and then yes, in just a couple seconds it's cuts off and I get the flashing light.

Here is a video of what the clutch was initially doing Before the replacement https://imgur.com/a/y83oND7 I don't think it was electrical to begin with. I'm willing to bet I knocked something lose or messed something up with the harness going between the compressor and lock sensor when I did the install.

Unfortunately electrical has never been my strong suit other then plugging harnesses in places, but this info is definitely going to give me a good place to start on the diagnostic. Thanks for all this info buddy.

 

I could not find out this issue and ended up taking it to a shop, the shop's diagnostic found that the ground fault was coming from the new AC clutch... smh...

I just had them replace the whole compressor.

So I'm out $1500 for that, $100 for the AC clutch, and a Saturday and Sunday of cursing trying to get a damn snap ring on the clutch installed. Turns out that the ground wire was rubbing on the new AC clutch, and it sheered off. It was then grounding itself on the clutch which was causing this issue. Not sure if the part was junk or I did not do a good job installing it.

Regardless, at least now I have AC in my 20 year old truck that's blowing 32 degrees.

 

Thanks for coming back with an update, srry it cost you so much to fix.
