Hi I am having trouble getting my air conditioner working again, I bought a kit to refill the system thinking that was the problem I put a minimal amount of pressure back in the system like the intructions said with out the truck running, then I started the truck and added the rest of the can into the system and right away the compressor kicked on and off three or four times quickly and then stopped coming on, so I went into the truck to have a look and the ac light on the dash was now blinking it was'nt doing that before I started, any ideas? 1992 gmc sierra 4x4 5.7lt
Disconnect the NEGATIVE wire from your battery for at least 1 minute, then reconnect. This will reset the computer and if you did not over fill, the problem will be resolved.
ON MY 92 SIERRA THE HEATER A/C CONTROL, THE A/C LIGHT IS FLASHING ALL THE TIME, A/C STILL WORKS AND GOES AWAY WHEN YOU TURN THE HEATER ON. I'AM THINKING SENSOR OR RELAY, BUT WHICH ONE AND WHERE ARE THEY.
Sounds like a problem with the censor or a bad pig tail, try unplugging the pig tail and sticking a paper clip in both sides and then turn the ac on, that will tell you which it is

Antifreeze is only for the radiator, does not affect the air conditioner, make sure you have the setting on cold, if it is still hot than take it to your local air conditioner re gas station, most auto electricians do it, dealerships usually send them out which you end up paying extra for!!! You just need a re gas in your air conditioner.
Hi, determine if your car uses R134 or R12 refrigerant. You will notice screw type connectors on the both the High Pressure Side and Low Pressure Side lines in models using R12 refrigerant. R134 compatible models have quick connect valves on both sides. Models made before 1995 may use the old R12 refrigerant. If this is the case, you must have your Chrysler's air conditioning system retrofitted to use R134 refrigerant. Mixing R12 and R134 refrigerants is dangerous and may cause damage to your vehicle.
Check your air conditioning system pressure using an automotive air conditioning pressure gauge. Keep in mind that in order to get an accurate reading, the air conditioner has be turned on the coldest setting with maximum blowing power.
Remove the Low Pressure Side port valve cap and set it aside. The location of the port varies, but it is usually in front of the engine block. Attach the refill hose to the port on the Low Pressure Side of the air conditioning system. The Low Pressure Side port is smaller the High Pressure Side port. Because the ports are different sizes, the refill kit hose should fit only on the Low Pressure Side port. Additionally, the High Pressure Side port will usually have a red cap or be marked with an H or the word High
Allow the air conditioner to **** the refrigerant out of the can by slowly turning the valve on the refill kit hose. Pay attention to the way you hold the can. Most kits will have you hold the can upright when you recharge the air conditioning system. It may take as long as 10 minutes to empty a single can.
Turn the valve to the off position and remove the refill hose from the port. Recap the port before closing the hood.
Let the air conditioner stay on for at least 30 minutes. This allows the refrigerant to move throughout the entire system.
Take care
If the blower works but its just not blowing cold air, its possible to recharge the AC system yourself. Most auto parts stores carry AC recharge kits. Instructions to recharge the AC are belowl
RECHARGING AC SYSTEM
1.Turn the truck on and turn AC on HIGH 2.Locate the low side AC line (will have a valve and cap similar to the cap on a tire) 3.Insert the oil or R-134A can to the hose (Do not turn the screw to puncture the can yet) 4.Insert the other end of the refill hose to the low side valve 5.Puncture the R-134A can with the screw on the refill hose 6.You should feel the system suction the refrigerant out of the can 7.Check for frost on the AC lines and the air blowing inside the truck 8.If frost develops and the air is cold, you've successfully recharged the system and disconnect the refill hose. DO NOT ADD MORE REFRIGERANT...overcharging the system will damage your compressor and will be less effective
Best of luck and enjoy your vacation. Greg
Hopefully this answers your question and you're able to get your AC working again. Best of luck.

Apart from doing a low side pressure check, you can try to recharge the system yourself with a refill kit that's readily available at most auto parts stores. If you're concerned about a leak, also get a can of R-134A with the UV dye that will show any leaking components. RECHARGING AC SYSTEM

Sounds like the A/C system just needs to be recharged. When was the last time you had this done? Just take it in to your mechanic and he can do it for you and if that's not it for some reason, then he will be able to find the problem but most likely you need more freon added.
You need to refill the A/C. It works on pressure in the system if its below operating pressure it will not work at all. Buy a refill kit and follow instruction.
Sounds like there is a refrigerant ( freon ) leak somewhere in the system. The A/C system will have to be partially refilled, and then leak tested. Only then will an accurate cost of repairs able to be determined. Hope this helps.
Air conditioner will not work if low on r-134a coolant. System has to have pressure. You can charge it yourself by buy a air conditioner refill kit at any auto parts store. If you don't know how to do it sometimes they will do if for you if you ask.
