When i run my AC it discharges freon from somewhere by the compressor

freon ok ? compressor ok ? if both lines feel same either compressor not working or no //low on freon

Are you talking about the hi or low? If you traced the wiring it will lead to the pressure switch The hi switch is located on discharge side if compressor before the condenser cooling radiator. Be damn careful Do not connect Freon can to high side you risk serious injury. Perhaps you will better served by letting a repair shop do this for you. You may have unseen problems, it may the ECU that is holding it out. Freon is not something an inexperienced person should not deal with.

to start with it will be high vacuum reading as suction is low pressure
secondly it means that the system is vacant of any gas and is well below 0 psi
if it is a high discharge pressure ( after the ac compressor) it means that the condenser is not being cooled by the fan or you have excessive gas in the system or the tx valve is blocked
I strongly suggest that you seek the services of an accredited ac specialist shop as r134a gas runs at a lot higher pressure that the r12 or r22 gas before you do serious damage to the ac compressor and system

The ac compressor has a switch under it most of the time people
replace compressor please be carful you have to discharge system before pulling swith off compressor even then that switch
let a pro take a stab at it danger I would take it to shop I work on car a lot replace compressor assemble better anyway last longer
to hot to break down do it right first time cheaper in the long runlong run

If the compressor locked up the chances there are metallic parts in the rest of the system are great. Flushing out the system is best left to professionals. If your system has not been converted from R 12 freon to R-134a freon, now's the time to do it. The oil in the R-12 system is not compatible with r-134a. If there is still freon in the system you cannot simply discharge it into the air.. The fine is huge. Have an AC shop do the work.

I am going to assume you meant AC Compressor as the condenser is basically like a radiator in that it cools the freon.

I would say that your freon is probably too low to kick the compressor on. This could be simple as adding some freon (With Leak stop(just to be sure)) would get it working again. The question is, why did it get low? Could be just age and it needs a little freon but usually means that there is a leak somewhere (Hopefully it is not the condenser leaking). Some leaks are small enough that you just need to add freon every month or so but they eventually get bigger. Look for oil around the AC connections and hoses. Could be an O-ring that has gone bad. Hopefully it is simply low on freon.

do you have freon in the system because the low pressure switch will not let the compressor run with out enough freon dont know where the switch is but it should be near the dryer there is also a diode in the harness going to the compressor

There is a high pressure relief valve on the compressor to avoid over filling the system and locking up the compressor, or blowing a A/C hose, ect.,
You need a set of gauges to do it right (connected to high and low ports) then read this.

You have a leak somewhere in the ac system. I'd add some freon for now, but you need to get the leak fixed eventually. Just go get a can of freon and follow the directions. It's really easy

Get a freon charger with a guage and make sure the unit is at the right pressure when running. If the unit starts and then stops you usually need to add freon because the compressor is running dry because the charge cant keep up with demand.

Add freon slowly and be sure the ac is on. A small puff....and wait to see if compressor comes on. When it does you can add until the guage reads in range. Try to keep it in the mid to lower end of the range. Believe it or not the fuller units dont run as cool!

Be careful! Adding freon too fast to a compressor can cause "slugging" and can damage the system!
