I can verify with my 2010 acura tsx 2.4, the 3 pin connector, you make the jump between 1 & 2. After I did that, the compressor ran without cycling on and off. It was just ON. It allowed me to add the appropriate amount of freon. Now i need a new ac pressure switch 🤑 thank you so much RB the mechanic. You helped me big time with these diagrams.

[@RBTheMechanic]

U have to vacuum the system to add and use machine

[@jdrems4580]

I have a 2006 jeep liberty. I tried recharging the system, but it wont take refrigerant. If i jump the ac clutch relay the compressor kicks on but it wont kick on when i try to jump the low pressure switch. The low pressure switch is new. I replaced the compressor because it burned up. I put the gauges on and the ac system and it has no leaks, it holds a vacuum. I haven’t changed to orfice tube or the receiver drier. What could cause the low pressure switch to not be jumped?

[@rickwaa2919]

Just a word of caution to all you guys, anything more then two wires has a 5 volt reference wire going back to the computer...PLEASE identify this 5 volt wire before you attempt any bypass. I have seen it go wrong. The motor will stall and the computer will be fried and suddenly you could be out a grand and maybe even a tow to a dealer.

Yuppp

[@ANGIEB52]

Yeah, I just tried this before reading this 🤭🧐🤔 When I jump and get the fans going the ac console freezes up …

[@RBTheMechanic]

@@ANGIEB52 so it could be ur pressure switch u still need to test other things

[@danielsmith9130]

😊🙏 thank you!!! I was just about to test a 3-wire setup... No thanks! Headed to the store to get a multimeter and replace the switch....

[@RBTheMechanic]

@@danielsmith9130 yupp good idea!!

[@johntoyin5425]

Thanks for the video,. Pls with 2006 Infiniti QX56 do i need to evaquate refrigerant to replace the presure switch or does it has a valve?

[@RBTheMechanic]

Not sure if it has valve I would recover the Freon from systym just to be on the safe side

[@MyPostville]

07 Honda Odyssey - relay is ok - i jumped the relay & i get power in to the compressor however with the relay in place nothing happens , any ideas? faulty pressure switch? Tnx!

[@RBTheMechanic]

Did u check to see if ur systym had as Freon pressure?

[@MyPostville]

@@RBTheMechanic @the end was a faulty compressor

[@AnDr1LLox]

Does the refrigerant have to be evacuated on Odyssey 2005 to replace ac pressure switch or does it have a valve?

[@RBTheMechanic]

I don’t think it has a valve

[@AnDr1LLox]

@@RBTheMechanic thank you for the reply. It did not and the system had to be evacuated. Thank you for the information.

[@thamwaikeong5885]

My old car has just a simple two-wire switch screwed to the top of the receiver-drier. Is that the high-pressure liquid side ? Do I just pull out the connector and jump the two pins ? I find this switch a nuisance and unnecessary expense. My previous car never had such a switch on the receiver-drier.

[@RBTheMechanic]

Think so some cars have 2 switches what car is that year make model?

[@thamwaikeong5885]

@@RBTheMechanic I am in Malaysia. It is a 1996 Proton Saga, with the Mitsubishi 4G13, 1,300 cc engine. The airconditioner compressor is a Sankyo (Sanden) SD-505, with R12 Freon gas.

Hey Mac Please help me with my car 2 pin ac pressure switch. How I can check it with multimeter. I just don't know what position should switch will be either closed or open ,when car ac is on and when car Ac is of. I am Checking it with Continuity . When my car ac is off ,the switch shows no continuity means switch is open. And as soon as I turn my ac on switch shows continuity means switch is closed . It it how it works .

[@Anonymous-nc2jq]
