2004 first gen Tacoma ac problems

Hello everyone this is my first post I hope I put this in the right place, I’ll get to the point I basically replaced from the condenser to the ac compressor, I have hooked it up to a machine and found no leaks, the compressor worked before I put Freon back in and it stoped found a broken ground and fixed it.
Now it doesn’t engage at all.
Is there any advice on what I could try to do.

 

First thing is check the fuse... you should see as long row of fuses in the engine compartment fuse-relay box, it should be the bottom one marked AC and is 10 amp.

 

sorry for the late reply I check the fuses and switched it out with a new one I still have the same problem.
I have replaced the condenser, condition receiver, and expansion valve. someone had told me to check pressure switch but I cant really find any information on it as of right now.

 

The pressure switch in behind the glove box. If you have continuity between input and output then the switch is not giving you problems. Can also check for power on switch output. If you get 12v the low pressure switch is not the problem.

This video shows exactly where the low pressure switch is (actually called dual pressure switch on 1st gen): https://youtu.be/MokkOp6uJeQ?t=162

And the diagram on page 2 of the attached pdf will help you figure out which terminal is input/output on the switch

Did you replace the AC clutch along with the compressor? If you are getting power to it but its not engaging thats most likely the problem

 

How much did you put back in? Was it measured or just a can from oriellys etc?

 

it was a machine we have a work it reads the pressure automatically and puts the right amount as far as i understand.

 

thank you ill look into it this weekend when i get some time, I'm thankful for you're time!

 

I replaced the whole Ac compressor.
