Gbody Single Wire A/C compressor troubleshooting

[@CuttyNick88]

First, let me say I appreciate your videos. You are the reason I went with the March Serpentine kit. I figured this out today on my 88 Cutlass and thought about this video. My system is slightly more intact (still has factory relay), but I had to jump my green/black wire on the factory relay to the solid green wire (2 solid green wires but both worked the same). After I did this, I followed the steps below. *Using the multimeter, insert red lead into the green/white factory connector with a resistor and the black lead into the black (4:16). *Take the single green/black wire and insert it into the solid green side on the weather pack connector (4:22). *Turn on A/C and check for 12V. If you don’t get voltage, you may need to insert green/black wire into the green/white side of the weather pack connector. This should allow the factory pressure switch to control the compressor cutting on and off when desired pressure is reached. You also can check for a bad pressure switch by using a paper clip or wire and jumping the switch (9:36). Also, the larger square connector with red wire is your main power from the fuse box so that will need to be connected as well (7:31). Hope this helps!!!

Thanks bro!!! I still haven’t revisited my A/C yet so I literally just screenshot this and saved to my phone!!! Thanks bro!!!

@@87SSBOI No Prob. I'm in the process of getting some lines made. Once done, I plan on shooting a video myself to help out others.

@@CuttyNick88 that would be great!!! Hit me with a link when u do it!

Great video and thanks for sharing. That plug with the blue tape on it looks like the one that plugs into a sensor that was on the factory thermostat housing.

[@87SSBOI]

Thanks!

[@vgslife9640]

some of the plugs went to the old ecm. the plug you plugged in for your a/c also goes down to the starter wires run from the left side of the bulk head that plugs into your fuse box. great video bro.

[@87SSBOI]

Thanks for the info 🫡💯

[@derrickbosley8889]

That plug controls the high fan speed + AC switch💪🏽

[@derrickbosley8889]

The one you hooked up is the one I'm referring to. The flat plug connects to your OEM AC... The last one I'm unsure.

[@87SSBOI]

@@derrickbosley8889 Man thanks for that because my high speed is intermittent...went and pulled that plug and inspected it...it had minor corrosion and one side of the connector was dry-rotted so it was loose...took That side apart and re-terminated the ends and now it's solid!!! Appreciate your input 🦾🦾🦾

[@mr.g.d.i.y]

Yoo. I’m late on your video but yeah he’s right also I’d advise you to get the electrical service manual for your car it has everything you need to know in it. I have one and it will be the same as yours since we both have a 1987 ss

[@87SSBOI]

@@mr.g.d.i.y Thanks bro...I will get one, that will help a lot!!!

[@bhwjrproductions]

That wire with the blue tape on the top of your motor plugs into a sensor on a power steering hard line next to your steering box.

[@julianhinojosa9695]

Some good info. Trying to install a serpintine kit with a single wire a/c. Thanks

[@marcschneider1777]

Yo SSBoi, i'm dealing with the exact thing like you do. I'm kinda trying figuring it out myself. My question to you is where did that single light green wire come from? was it just dangling in your harness? On the 86ss i'm working on the only light green wire i can find goes to the low pressure switch on the dryer then comes back out and goes down the airbox and plugs into the connector you showed that was unplugged in your video. Heads up to you and this video. The comments along with your info might just solved my issue.

[@87SSBOI]

I appreciate you watching bro!!! It’s been so long ago I honestly can’t remember where that wire came from

[@draysgarage8877]

I don't know if you have it figured out yet. But I would use the green wire from the black connector. Also I believe if won't get 12v till black connector on the dryer sends it.

[@87SSBOI]

Thanks bro...I'm still in the process of figuring out out completely...I appreciate the input 🦾

[@GetMooreProductions]

I have a 87 as well. I just got done putting a 350 fuel injection Jasper engine in it with headers. I'm running into a little bit of AC problems too once it gets warmer I'll be checking mine good look on the video

[@87SSBOI]

Yessir!!! Hope u get it figured quickly!! Need that A/C!! And as old as this vid is I still don't have my A/C hooked up 🤦🏾‍♂️...I only really ride evenings n night tho but still want the luxury of having it

[@oldschool337]

If I’m correct that double plug is for the compressor it should have 12 v when ac is on but it won’t because the green one goes to the low pressure switch and supply power to the compressor harness

[@oldschool337]

$15 binary switch will fix it.

[@Unchained32]

Hate to trouble you but I’m having the same problem with that same wire that plugs into the compressor.It doesn’t even read 1 volt. But the plug in to the accumulator read 12 volts. Any advice?

[@corneliushall1800]

Wits up bro did you make another video on this? … I’m getting ready to start on my ac an was wondering how you wired it up

[@87SSBOI]

Nah I didn't...the AC got put on the back burner til now...I will be posting the progress...dropped one today on some AC stuff as well

[@corneliushall1800]

@@87SSBOI ok I just watch the new drop… ! I’ll be waiting

[@MrBhustle]

the plug with the resistor on it is the ac plug. I believe that other green wire is the high pressure switch for the ac. 👍🏾👍🏾👍🏾 keep up the grind

[@87SSBOI]

Thanks bro!!! That's what I was told the one with the resistor is the for the OG hookup on the pancake style compressor...not sure exactly where the other green wire came from but that's what gets power when the a/c switch is engaged so I'm thinking that's what I hook up to my single wire system

[@TonyBone1986]

Nice! Where you get the AC lines from?

[@87SSBOI]

Custom made at some line shop..i don’t recall the name

[@eknockout1]

Was your blower coming on before this mines come on but not compresser

[@87SSBOI]

Yes that’s the blower spinning in the background when I switched the key on

[@regrich8795]

Yep that double wire plug definitely connects into the OEM compressor....

[@87SSBOI]

Yep...it's weird tho cause I didn't get any power thru it but I got power thru the single green wire when I engaged the A/C...I'll revisit all the wiring once I set everything up...thanks bro 👌🏾

[@regrich8795]

@@87SSBOI yeah that's strange

[@Se7enthsonSS]

I feel like I’m blowing up your page with questions….I see your lines go across the front to driver side. Did you not use the cutlass AC compressor?

[@87SSBOI]

Nah u good bro...this was before I switched to Cutlass condenser

[@jamespeoples4657]

About the green wire that gave you power every time you turned on ac switch, wouldn't that give power to compressor even when not enough freon in system? Wouldn't we still need the pressure switch to send the power? IM CONFUSED

[@87SSBOI]

I haven't made it that far yet...still learning myself...lol

[@terrylinellc5550]

Hey where did you get that radiator support from?

[@87SSBOI]

Dixie Restoration Depot

[@thomasdennis9620]

That Green wire is for your fast idel. The Green with the resistor goes to the compressor

Thanks

Great tk bro and try in my cutlass

Anytime🦾

How many row champion radiator you got and does it keep it cool?

That little small box green and black wire connects to the ac compressor

[@johnniegregory2666]

No problem

[@johnniegregory2666]

Question brother I got a 86 Caprice and the same ac setup you have on your Chevy I been trying to trace all the AC wires that's for using the AC you think you can take pictures of where they are and send them to me so i can know exactly what's what really appreciate it thank you

[@boss94ways51]

Im late to all your videos...im sure you probably figured it out by now...but that purple a gray hose are your vacuum lines 1 goes to carb..1 goes to heater control valve..he built a cutlass and did alot of things do it..FYI..

[@87SSBOI]

Yea I did...I appreciate that tho!!! Thanks for watching 🦾💯

[@johnniegregory2666]

The wire that you was holding that you think it goes to the factory ac compressor it does that's what it goes to the factory ac compressor unit

take it too a shop u go burn the car up

Nah homie...I got this just like erthang else

Yes indeed because most shops be experimenting if they don't know.
