ok i need your help. 1995 gm s10 2.2l(4cylinder) truck.. ac not working.. if i apply 12volt to compressor clutch clicks.. only pressure switch is on compressor 2 wire.. if i paper clip two wires on pressure switch nothing.. no cut on.. i checked all my relays i have 3 on back of firewall(5pin) with 12 volt test lead.. they click.. I’ve replaced all my o rings and the two crush washers on compressor. I replaced the small ofice tube.. still compressor not cutting on .. i replace dash controls still nothing.. at loss? Any ideas
Check if you have refrigerant in the system, of its up to 100psi startic pressure on both sides, start the car and apply battery voltage on the compressor, with the blower speed at 2 or 12 o clock. If ac blow cold
Ok sir ,I subscribe I gave you a thumb up ,my friend car is a 2019 hyundai kona ,they brought it to the dealer the dealer told them they need a compressor, they replaced the compressor, they replaced all seals they spent lots of money not realy sure what they did ,when I checked the car it has no codes ,the freon was empty, I added 1234yf it worked for seconds then stop ,I used autel scan tool to actively the relay wit engine off key on I herd click,when I try to activate with engine running it says fail.,what do u think
Welcome to the family, Sorry for that sir, this dealership have done a terrible job, they failed to perform a comprehensive leak test before recharging the refrigerant. If they have sealed the system completely they is no way the system should be empty. I suppose they gave you warranty so kindly get it back to them to double check where the leak is coming from
@drcoolautofix they took the car to 3 persons before me ,I saw a list of work they did ,witch was almost everything except the evaporator ,but the only part they showed me was the old compressor, I don't have the wireing diagram ,I'm supposed to look at it tomorrow, if I have the wiring diagram I can do more test ,thanks anyway
This is a test subject which is only intended to be used and verify if the sensor is the problem. It will not fry anything however I don't recommend you using it that way. Replace the sensor afterwards
Great idea on using the coin battery... Should work great
Great content ❤❤
Thanks for the video... Need to do this on a 3 wire Porsche connector ... How can I make sure which is signal, and which is negative?
Thank you for the help
Thanks so much bro
thank you very sir for sharing...god bless.
Always welcome
On the toyota after you connect the two wires on the side do you need to plug it back again? Or just left the plug disconnected?
Either ways works
can you do a picture of the 3 pin with coin?? did you say center postive and which end goes to neg batt?
I repair ac units and ran into this

Will this fry anything or mess anything up?

cant understand what you said about the negative part of battery
Replay it if you don't get it
