Get a can of your vehicles coolant and recharge the a/c with a can or 2 of your specified coolant theres really not much to do to putting a can on screw on to nip turn vehicle on and let the can do its job make sure to match your coolant specifacations
you can buy the add on cans almost any car part store

1993 Eldorado Cadillac ac compressor won't take freon. Display says compressor off, low refrigerant. How to bypass computer? Can compressor relay be jumped using paper clip? Which holes? to


Grab some refrigerant gauges and take readings. If the low side has more than 40 psi or so of pressure, the low limit switch will close and allow the compressor to run. If there is indeed low pressure causing the compressor not to run, you will need to flush the system after eliminating the source of the leak. If the a/c compressor has never been changed, it is probably the source of the leak.

I have a 1999 Cadillac Eldorado ETC. When I turn the heater on and bring it out the bi-level vents....The driver side blows heat and the passenger side blows ice cold....even with the air cond. turned...


the temperature door inside (there is two one for each side of car) is possibly broken if you turn the blower on low turn the temp on the passenger side from full hot to full cold or vise versa and listen closely for a clicking or snapping sound if this is heard you have a broken door in side then the dash has to come out the air conditioning has to be discharged of refrigerant which has to be done by a facility with a license. if no noise is heard it could be a control head or a motor but the most likely cause is a broken door.

AC comes on, then shuts down before car is cooled. Compressor activates and blows cool air for about 15 seconds then shuts down.


Low on R134a, you need to have the system recharged. Try to stay away from the do it your self kit that most Auto Parts store carry.
Below are normal car AC pressure readings with 134A

Normal readings on high and low side with AC OFF (static pressure) – Depends on outside temperature, but normally is between 80-105 PSI

Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s – Ranges from 25-35 PSI

Normal high side reading ranges from 200-350 PSI

Don’t assume that if adding little Freon is good that adding a lot is better! Overcharging just a little can decrease the performance of the system and possibly damage the compressor.

Thank you for using fixya and good luck.

Digital dash reads out low coolant and runs hot.


it means just what it says..your low on engine coolant and that is causing it to run extra hot...this is not good! let car cooldown and take radiator cap off have a look inside with a flashlite..water level should be almost up to the filler neck. if you have the red dex-cool you"ll have to put in the same its not recomended to mix the green and red. if it doesnt your in luck just fill up a jug or get a garden hose and fill it up to the top if its low. leave cap off for now and put some water in the coolant tank if its empty only about halfway dont overfill. now start the engine and let it warm up for about a minute and see if the water level goes down if it does add a little more water up to the neck, now turn off the engine and let it stay like that for another minute to make sure trapped air can get out. Now put back on the cap. Now go for a 10 min drive around town and then see if the warnings have cleared and its running at a normal temp range. also park in a new locating so after you turn your car off you can check to see if its go a slow leak overnight.

A/c compressor not working added freon but it


Either the system is still low of freon,or the sensor (one of them)is bad.The sensors are on the high side of the system,liquid line.If you will get on chat,I can help you with this,it will take a while,I will need to know how much freon was added.And what the system is doing,is the ac clutch engaging,etc?Ask for ronicon,when you click on chat with,type my name in,roniecon,with your text,that you are writing .

Air cond dash light works, compressor doesn't go on.


AC's have a low freon switch that shuts off the system to protect the compressor in the advent that you have a freon leak have the system checked for a leak
