Engage AC Compressor Clutch with a Paperclip on Relay | How to Fix Bypass Won't Engage | Jump Relay

Believe it or not, In most dealship workshop manuals this is step #2 in troubleshooting the ac compressor.

Congratulations!!! After clip insertion u now have pin fitment issues.

I just did this on a 2009 Chevy Traverse the freon was so low that the compressor would not come on did the paperclip trick put two cans of freon and a pressure gauge is just barely in the green on the gauge will get another can or 2 wouldn't have no idea how much money I just saved myself but would probably be $100 or more for sure a big thanks for the video helped me alot

Will the refrigerant go in without the compressor on AND when it gets to the right pressure will the compressor start......what if the system is depleted of all refrigerant and you are just putting on a new compressor? Will running the compressor without any refrigerant ruin it?

So I've got a question on that. You jump the relay like that with the vehicle off correct and then as soon as you turn it on it should make it engage but you will not hear any kind of click as soon as you insert that paper clip with the vehicle off correct?

What if I have Freon in it already but it just not staying on like it supposed to ?

The button on the inside of my van isn't working, can i use this method to bypass the button using wires running in to the cabin?

Thnks. May need to do this to check my ac not working after car battery replacement. System is dead. Reconnected battery. Same. Ill check relay and fuses. Anything else to check for if ac fails after battery replace? Btw. I can connect 12v to the compressor clutch side of relay to force voltge there if need be, right?

After my car sat for a while and i finally got it to a mechanic to fix the alternator i got it back with nothing but hot air blowing. My ac used to be AMAZING. Hubs says the ac compressor clutch thingy isnt doing its thing. He got the can to refill it b4 he knew this and the damn pressure was TOO HIGH. csn he just let it all out and redo it or should i get a new fuse. I need a new car

I did this to get the ac clutch engaged, but when I checked the freon it was at the minimum green level which should be enough, but is still blowing hot (just outside air in not heat), not sure what else to do

I did this with copper wire, do you think it can last longer? Or affect performance? Im planning to use this method permanently

I did this and my paper clip turned red any ideas wats wrong ? Every time I turn in my ac the fuse blows

Did you need a new fuse/relay ? , is it safe to leave it like that?

What if this does not work?

I tried this the other day the clutch kicked in and a few minutes after something went bang and I think a hose burst

hello, my car doesn't want to do that, turning on the switch in the cabin starts the engine fans. There's simply no electricity, what do you think

Thank you very much sincerely. Saved me a lot of time and money.

With this video you showed absolutely nothing about clutch engaging or not engaging

amasing 3k likes on dumb idea :-)))

why u have to engage compressor if there is no freon????? u start filling it up- u get clutch working !!!
thats how it works for gods sake. In most cases if there is little freon and compressor still working but hot air.. but if there is freon and its not working ! u need replace compressor

Can I keep the paperclip on there? or will it harm my car? I took it off and put a relay but it wont turn on

It worked for me but when I replaced the relay the clutch doesnt engage? Is this the relay that may be broken?

U cut scenes idiot. Learn how to make a full video

,

Does the key have to be on "on" position or on "running" position to get this test right ... i have the key on off position and there is no sound or clutch engaging

Thanks omg this is best yet I taught you taught my step dad some new

So I imagine if bypassing the relay doesn't do anything that means my compressor is shot right

Great Advice... I didn't know what was wrong with AC system. This technique allowed me to get the Clutch engaged. And since I had a can of refrigerant, I bought thinking it just needed a charge, I added the can to system. With one can I felt I might be getting cool air. Ran to auto store for another can... added just a little from 2nd can and YES!!! I have cold air. Thanks so much!!

I tried this on my wife's car 🚗 and my neighbor's house exploded

Thk you

I have a kia Sportage 2014! In the mornings whenI start my car and the a/c the compressor clutch wont kick in. After I run the car for about 10 minutes or so the compressor kicks in! Pls advise!

Why can't you turn it on in the car?

Amen! Great help. Had the same rock and a hard place issue with the compressor not engaging due to being empty on refrigerant.

What I'll do is I'll take for example the windshield wiper relay normally they are the same relay I'll take out the relay and put it in the AC relay as long as the numbers match they are the same relay then turn on the AC and see if the AC clutch comes on or not if that relay is working on the windshield wipers for example then it will work on the AC clutch so I just take one that's exactly the same number see where it goes and I will swap out the relays and see if the relay is good

Genius!

Just add refrigerant until the low pressure switch is satisfied and the compressor will safely start. No bypassing of the compressor protection is warranted to charge a system with low refrigerant . No harm done if enough refrigerant is added before compressor damage occurs.

Looks like it would work?? Wish me luck! Getting AC working in my wife’s car would sure make me a happy camper! Thanks!

What happens when you try to fill without the clutch engaging? I realized after watching the video that the clutch was not engaging but was able to fill? Is it a thing that the system can be charged but there is an issue due to the clutch not engaged when filling?

If this works does that mean there is an issue with the relay or fuse?

Thank you Sr this video really helped me to fix my ac problem

I have the same problem, new dryer, ac compressor, power going to try e compressor, low sensor works, but when I cross over the relay the clutch still won’t engage, any thoughts? I’m stumped at this point

Why don’t you have enough refrigerant? Was there a leak? I though it was a closed system. I’m trying to figure out if I have same problem or if it’s my clutch that is bad and I need a new compressor?

Worked for my 2006 Kia Sportage. Thanks :)

I have no idea what you're saying

Tried this compressor kicks on, everytime I turn ac on but still no cold air ?

That was a great help

wow cant believe it was a dam fuse. I changed everything and it was a fuse. I always check fuses lol.

Why would they design the compressor clutch in such way? There should be a manual alternative to engage it without using paper clips or jumper cables.

Unfortunately, the compressor replay for my 2012 Nisson Quest is under (and part of) the fuse panel, and isn't serviceable. The want you to buy the whole panel I guess.
I want a HORSE! 🐎 To hell with cars and the cost to keep them running.
