Stoped the AC doesn't work properly and is charged ,where is the fan controlled temp sense if there is one

Test/scan fan control circuits for both A/C and engine cooling first to find the cause , save money on guess work. describe what you mean by 'A/C doesn't work properly? --Not cooling ? compressor short-cycling? Condenser fan inop.?
Ok , ac gets cold while the compressor is on,but compressor won't stay on ,it looks like both fans come on normally if you don't use the AC . If you run the AC the fans stop working after a while and the car gets hot .the compressor does short cycle for a while but stops working after the car gets to 180 or higher.i did add some 134 a and pressure is about 150 psi
Do you have a scanner to watch live data and what kind of gauge set are you using? Need BOTH sides high and low pressures. Fans should be on WHENEVER the compressor is engaged. Would be good to see what the PCM is commanding.
I don't have a scan tool , but I did check to see if the fans come on when the AC is on and the fans do not come on automaticlly when the compressor is on .I'm just using standard ac gauges for 134a , and it's 150 on the high side when the compressor is on.it just seems like the AC is over loading the fan relay or fan controller and stops the fans from working until it cools down .I do have a volt meter if that can be used somehow .
BEFORE more damage is done , get a good source(either factory manual or 'alldatadiy.com'-small fee) for circuit description , and component location and operation. I'm pretty sure the fans should always be running when compressor is engaged , and most likely they are CONTROLLED by a separate circuit than the cooling fans. FIX the fan problem , and it may fix the other problems. PROPER system information is the key.
