This could the restrictor valve ,but to test you will need the correct machine that empties the gas weighs the extracted gas and vacumns the system before recharging ,best advice is to take it to someone who has the correct machine

My ac compressor wont come on but when i bypass it it work but doesnt cool


You need to have gauges put on and system tested. Sounds like might only be low. System will not kick in if low.

On my BMW 325XI Wagon, the ac is not cooling, the drier, expansion valve, compressor & ac control module have been replaced. Starts to cool as low as 65 degrees & then compressor shuts off.


sounds like unproper ac evacuation before charging the freon to your ac system. do a proper evacuetion to the system check the ac compressor oil charge the proper freon & amount check the vehicle tag for the amount of freon under the wood close to the radiator

Is engine temperature badly affect AC compressor prformance ?provided that i bought a new compressor since 9 months but now stop function despite adequate fereon


It should not affect the A/C compressor. The A/C coils are actually in front of the radiator so the A/C should cool regardless.

Here's what you want the system to do. You want the Freon to maintain a steady pressure when the A/C is on. There are 2 pressure cutoff switches. 1high, 1low pressure. The compressor will cutout when either switch is tripped. This means a moderate amount of Freon is supposed to be in the system to avoid tripping the switches.

At this point your dryer tank will frost or sweat, the lines from the tank will frost too. The Freon can remove the most heat in this condition.

You can loan tools from Autozone or Oreillys with a deposit. You need to measure the pressure in the system and have the car windows rolled down and air on high to make it perform. Also use the correct "oil charge", the compressor will fail without oil.

Your compressor will not start if the pressure is below the Low pressure minimum. You may want to change the LOW pressure switch. If the compressor does not start, check the fuse or add Freon. The compressor will not run if there is too much pressure. Measure and remove Freon to cancel the high pressure switch.

When you have your pressure right everything should work providing the system was properly prepped before the Freon was added. Final note, the manifold gauges show TEMPERATURE variables for installing Freon. In simple terms, Freon is a gas that expands and if you add it in Cold weather it will expand and have higher pressure and be overfilled in Hot weather.

AC IS NOT COOLING. FREON HAS BEEN CHECKED AND IS FINE.


Impossible to tell w/o the belt being installed. If the compressor is dead, no amount of freon will work. My guess is that they probably removed the belt due to compressor issues but if the compressor does kick on and there's no cool air, it may need freon. Freon can't be added unless the compressor is on and running.

Ac compressor does not turn on when car has been sitting & it's hot outside. Works fine in the morning.


either the freon charge is about 1/3 low, or the expansion valve needs to be replaced. Freon is getting into the evaporator, but not in great enough volume to cool the air unless it is coming in cool to start with. check your ac charge, and if it is full, then have it emptied, change out the expansion valve, and recharge it

Car full of freon, air conditioner still not cooling


Yes the system can be full of freon and yet not work, the pressure switch could faulty, the expansion valve too could be faulty, he drier receiver too.
On switching 'on' the AC , is the AC compressor workingor rather does it engage?
The AC compressor clutch too could be not functioning.
I guess you have to go step by step to check first if the AC compressor does rotate on switching 'on' the AC.

A/C blowing hot air. Compressor activates and system has pressure.


Could be the expansion valve. That's what allows the temperature to actually drop in the system - the contents of the AC system are under pressure, and are at a certain temperature. When the freon goes through the expansion valve, the pressure drops suddenly and dramatically, which "flash chills" the freon, allowing the air to blow cold. If it fails, you may get lukewarm air from the AC despite everything else working. Also though, check to see whether the AC evaporator fan (underhood) is working - on some cars, if it doesn't turn on, the compressor won't be run enough to cool the air.
