Ac low pressure switch


coolant has nothing to do with the ac system
coolant goes in a radiator
gas goes in the ac system and should be only installed by an accredited ac specialist shop using the correct equipment
If you have to add gas then there is a leak in the system
second point , when you turn on the ac compressor , and start to add gas ,when the gas pressure is sufficient then the ac compressor will switch on
Best to have the specialist do the job for you

MY 2001 ELDORADO AC WON'T ACTIVATE AS IT ADVISES THE REFRIGANT IS LOW. I TRIED TO ADD REFRIGERANT BUT THE COMPRESSOR WON'T COME ON TA INHALE IT SO HOW DO I GET THE REFRIGERANT IN? THANKS -JWB-


Hi, the way to get the compressor to come on is to short the connector to the pressure sensor on the return line. The sensor is along the same line you were trying to charge on. Just remove the connector and use a large paper clip to connect the terminals inside the connector. Please let me know if you have more questions, and thanks for using FixYa.

After i put the ac on my bmw x5 2003 get over heat and smell burn


pls. check your ac compressor magnetic clutch attached in front of ur compressor if its working/ ac clutch engage when u turn the ac switch on and disengage when u turn the ac switch off/ it normally makes a clacking sound when it engage with the rotation of ur compressor/ if its not engaging it means ur magnetic clutch is stuck up giving excessive load to ur engine thats why it overheats/ it smell burnt because its magnetic coil is fried/ or check cooling system of ur car might be that coolant is empty/ fan is not working/ radiator is clogged or thermostatic valve is stuck blocking coolant flow....

AC clutch engages and disengages constantly


the system is low on charge, as far as the attempt to add refrigerant u did something wrong, no sure what, the rapid cycling of the compressor is only caused by a low charge 99% of the time. Have u hooked up a set of gauges to check pressures?

Air conditioner not cooling.....


Hi!

First, I'd try checking your local Library for an AC repair manual. An Ac system has a number of different parts that all work together to cool.

That said, there are some things you can check that are easy.
First, Check the controls. Is the AC on, the blower on, and the temperature selector set on cold? Really check, because this is what is wrong about 10% of the time.

Next, with the car off, find the AC compressor. Is the belt still on it? Have someone start the car and turn the AC on while you watch the compressor. The outer part should turn, and when they turn the AC on, there should be a click, and the inner part will start to turn as the clutch engages.

Next, Look at the fans. If your car has an electric fan, it should come on when the AC has been on for while. If your car has a manual fan, then it might be the fan clutch, but there isn't an easy way to check this.

If it isn't one of the above, then you are probably out of DIY territory. Because of this car's age it probably has R-12, an older type of refrigerant that is no longer manufactured for environmental reasons. The $1100 for the compressor replacement seems high, but that should include evacuating the system and recovering the refrigerant, replacing the compressor, receiver/dryer, and expansion valve, flushing the system of the old refrigerant and oil, replacing the oil some that is r-134 compatible, and installing the updated fittings and o-rings for R-134. You can see how that adds up in terms of time and Parts.

Good luck!
