Hello, my name is***** will be helping you out! I have over thirteen year of experience in the automotive world for numerous different makes & models. I enjoy doing what I do, it is my life.
You need to know if refrigerant has to be extracted to remove the pressure sensor without refrigerant going everywhere?
Yes you have to have 0 refrigerant because it does not have a schrader valve.
removing it will cause refrigerant to come out.
Is there anything else I can help you with? Did I answer your question?
I will double check one moment
vin number please
I do not see a procedure for removal and replacement that shows no valve there , only shows diagram of location and procedure to diagnose a non working ac system.
is the ac relay good?
If the relay wasn't bad, remove the relay and check for battery voltage on two of the terminals. If there is no voltage to contact side of the relay, check fuse 20. Also check the fuse connections. Do not use a logic probe to check for battery voltage, they are not accurate for measuring battery voltage
attempting to bypass this one could cause ecm or ac control damage. you can monitor the voltage on the 5 volt signal wire to see what the volts are while connected. Do you have a scan tool? If you want a temporary fix, you can jump power to ac fan relay and ac clutch relay together would make the ac run and keep the pressure from being to high
You need a scan tool or at least a volt meter to really identify if the pressure sensor is the problem, sometimes a bad ECT sensor goes bad making the ac think it is over heating even though your temperature does not show hot & is not over heating. If you still want to proceed with jumpping the fan & clutch is up to you, I can not guarantee anything because it is not the "proper" technique. And jumping it will allow you to see if the system works, but not to see if the pressure sensor is bad. only a volt meter and scan tool can identify that.
Have I answered all your questions?
What else can I help you with? or would you like another tech to help you?
My pleasure, have you located the ac condenser fan relay and the ac clutch relay?
apply positive voltage on pin number 2 on both the ac fan relay and ac clutch relay. should be pink wire and blue wire.
if you are unsure which pin on the relay box needs voltage you can send me a picture of the ac relay location without the relay on it
yes if you have a smart phone apply voltage at your own risk and make sure it is the right pin. Do a quick voltage injection/release to see if clutch operates or not.
Yes you need a wire and possibly a pin that attaches to the wire so you can fit the power feed in the pin terminal of the clutch and ac fan relay
Anything that has power on the vehicle
That is fine
If you feel you are applying voltage to the wrong pin, then immediately remove
And if the compressor functions, you must keep power to the ac fan as well to prevent high pressure damage. and when you are done using the ac, remove your power feeds or install a toggle switch to deactivate power feeds
Leaving them direct will obviously mean they stay engaging always and will drain battery
yes 2 relays in the fuse box one for ac fan and other for ac clutch
here is the index, find two relays one for ac fan other for ac clutch
pull out the clutch relay and ac fan relay and put power to the appropriate pin and the ac will/should work, do you need anything else? Or can I put my rating up?
ok, have I answered all your questions? Can I go ahead and have you rate me?
No, it will be pin number 2 on each relay
prongs and relay and sometimes on the empty pin, let me try to find a picture give me a little bit of time.
Do not get a terminal description location on my end to determine that. only other option is direct power on ac fan itself and the ac compressor it self
if you had a test light that would be a way to determine this, but you have limited tools.
its a breeze to fix with the right equipment a scan tool is kind of a must to diagnose newer vehicles.
And i mean direct power feed to the red wire of the fan and the ac compressor
No, the pressure switch you do not touch, it can be done either by both the relays, or directly on the fan motor for ac, and directly on the compressor wire, look at the wiring diagram I sent to you. the compressor wire will be either blu/red or red/wht. The wire for the a/c fan will be Red or Blue. Only if you can not do it from the relays. These procedures again or not recommended nor guaranteed to work , but you have no equipment and scan tool and your asking for other solutions to get by and make it work for your dog. If you can not attempt by yourself, I would highly recommend to take it to a certified auto repair facility that can also read what the refrigerant level is. At this point, I highly recommend you take the vehicle to a certified repair facility to get it properly fixed with proper equipment. I feel I have answered your question and on top of your question, I also feel I attempted to answer more beyond your question. If you feel satisfied with my answers, please leave me a 5 star rating.
It was my pleasure answering your question. Now that we have either answered, or somewhat answered the question, I will offer my rating. Please let me know if for some reason you are not satisfied with the results I gave you, let me know because I strive for excellence & a 5 star. If you feel 5 star is not worth it, let me know what else I can do or change. Leaving a bad rating or negative rating only hurts me not the site. So please let me know if there is something I can do for you to earn your 5 star rating. Thank you. Sincerely, Michael.
I apologize, I am not frustrated, I just mis-understood the actual question. I understood it as if removing the pressure sensor would cause refrigerant to release, yes it will release refrigerant, if that was not the question, then I will have to opt out and let another tech assist you. Would you like another tech?
Unfortunately, you would have to open a new question and finish this one if you have a new question.
What is your new question?
Do you have a voltmeter?
Then unfortunately, I can not help any further if we have nothing to diagnose the issue with. You can put random parts, but I can not help you without the proper equipment.
Are you ready to rate? or would you like to seek another tech?
Absolutely,, Take care! Have a wonderful night.
You are right, I apologize the hard time relating to a novice perspective, but still tried to explain the best way I could to do some sort of by-pass, I could not see any other routes then the ones I have attempted for you. Thank you for the rating.
