Customer Question

im working on a 91 camry that when I put in the r134 it plugs up the air conditioning system the low side gets it in and it doesn't go thru to the high side but when I run it with air it blows thru with plenty of power and the system is opened air goes thru with ease. could the expansion valve be giving me fits.

Hello...welcome and thank you for using Justanswer.

I need to ask a few things before my answer,sorry.

Is the AC system empty ?

Are you using a bottle with a single hose to top off the ac ?

Did you vacuum the system to get rid of possible moisture ?

let me know.

Thank you.

i vacumm the system then thru gauges i install the can in the low side and it doesent seem to go to the high side but if i run the compressor it seems to push air thru the system with the line opened it holds 1.7 lbs
Expert:  I. Silva replied 1 year ago.

Ok , so ,after you charge the system with 1.7 lbs ...does the compressor come ON and what are the readings on the gages ,low and high sides ?

Do you get any cold air inside the vehicle ?

Does the radiator fan come on with AC on ?

Let me know.

Thank you.

the compressor will not come on because of the pressure switches on the high side if I bleed over some Freon to the high side it will come on but the gauges remain static or stay the same theres a little cold air comeing out and the fan does not come on.the compressor works good.

when I put the Freon in just the low side registers any pressure nothing on the high side. it doesn't go thru.
