Question about 1999 Ford F150 Regular Cab

A/c system 99f150extcab

I put a guage on the recharge line with a can of rga12,the new stuff. Anyhow the press. was about 90psi without adding any refridgerant, the press. stayed the same with the truck runningthere is a little cool air on the low setting but when placed on high it is hot. Seems too me that either something is stuck ,like a switch/relay or the pump is bad. I do not have alot of experience with a/c systems but I am current on other mechanical systems

Your A/C Compressor could be shot. I would take it in to get it inspected. Just because you have pressure in the line that doesn't mean the compressor is working.

Trying to recharge A/C system in 2003 Frontier CRew Cab. Do you have a diagram of system so I can locate high and low pressure lines.

To recharge A/C system in 2003 Frontier Crew Cab. Brother, don't concern yourself about the technical stuff of which is high or low pressure line. The refill/charge kit line will only fit on ONE of the 2 line fittings anyway. The line fittings I speak of are covered with a plastic cap like the one on your tire valve stem. Get your recharge kit from parts store, get mine from NAPA, with the line and a bottle of Freon. Find the charge fitting, usually on the passenger side under hood not far from firewall. Take the cap off and put it in your pocket. Open the kit, screw the piercing pin of the canister end out and put that end on the Freon canister. DON"T pierce the canister YET. Screw the other end on the charge fitting of your system and start the engine, turn on the AC on high, NOW pierce the canister top by screwing the knob/t-handle all the way in and then back it out half way. This will allow the Freon to escape the canister and the AC compressor will pull it into the system. Now, I've one trick for you. Before piercing the canister, get a small bucket of HOT water and have it there at the vehicle front. Soon as you pierce the canister and back the pin out half way, stick the canister into the hot water in the bucket. The heat will force ALL the Freon out of the canister till empty. Once empty, remove the kit line from the charge fitting on your vehicle, remove the canister from the kit line, trash the empty and hide the kit line where you can find it later, dump the water and put the bucket away, and go sit in the cool. One canister should take care of the recharge. If you put too much in from another full can, it may overcharge the system and still have no AC. That's just the nature of the beast. If it leaks down, get a leak detector kit from same place you got the recharge kit and find the leak. They also make a literal "Stop Leak" kit for AC systems too. Same place will have it. Brother, old school on this stuff. I figure things out quickly. There's no reason why this I told you won' work. It's what I do. Have fun Bro.

How is the best way to recharge freon in the ferrari 328.? any common point of freon leakage?

All vehicles will leak a miniscule amount of freon from the seals throughout the coolant lines, you can use a leak detector additive when adding freon or use a freon gas leak detector to find any substantial leaks in the system by guiding the probe around all the components while the vehicle and ac are running. You could use a heldheld freon charger with a built in pressure guage provided you have the correct fittings, otherwise I'd recommend having both your low/high pressure sides monitored while adding freon and making sure your compressor is turning on and off properly as the high pressure side reaches its peak.

Ac just stop working without any indication! where do I look for the problem?

Step 1) Check to see if there is AC Coolant in the line. There are many posts on this on the net. The low side is just behind the passenger front light. Remove the light and it is right there. You can get to it without removing the light but a bit tricky. Get a filling can and hose from parts place. Not too bad

95 honda accord trying to recharge ac. will only take a about half a pound on a empty system any suggestions

run a vacuum pump on it prior to recharging. Chances are you're adding refrigerant to air. But more importantly, if you're adding refrigerant, you got a leak. It's useless to keep adding refrigerant without finding and repairing the leak, and not removing all air out of the system prior to adding refrigerant

Air Conditioning suction and liquid lines are leaking and an accumulator was needs to be replaced. Can I do this repairal myself? Gary Davidson

Yes providing you have the tools necessary to disassemble & reassemble & the correct parts. You will need to recharge system after replacement. If you dont have recharge hoses & guage, may have to pay to have system evacuated & recharged.

Replaced the compressor in my 1999 Dodge Caravan. The pulley failed on the old one so I bought a new compressor with clutch. I recovered the R-134a and replaced the compressor. I recovered 1 oz of old from...

the new compressor was likely shipped pre oiled. it should have had a tag on it saying if it was oiled or not, and how much. if you added more oil, the system has probably been over oiled and hydro locked. recover the refrigerant again, if you are working with an actual automotive a c machine you should be able to draw that extra oz of PAG oil out, then recharge refrigerant. hopefully that will do it! otherwise, you could have a restriction in your system, possible from debris in one of the compressors, in which case you will need to flush the lines out. good luck!

A/C blows warm. I would like to recharge the

Let a professional do this, you will no doubt put TOO much in and overcharge the system without the proper pressure guages.

If you decide to do it check the haynes manual it will show you where the valves are for the low and high pressure side, they are usually covered by different color plastic covers.

Need help recharging ac iin a97 ford explorer

First it can be dangerous or fatal to service or attempt repairs or your vehicle's ac without the proper training or equipment so I will describe the proper steps for you to use to help ensure your safety. I'm guessing you have a standard recharge kit from walmart, autozone, etc. which consists of a pressure guage, screw on tap, valve, hose with attached fitting if yours differs let me know before proceeding otherwise, first attach hose to the low pressure charging port on the refrigerant line. This will be on the larger tube usually near or on the accumulator. the silver aluminum cylinder with several wire connections and 2 black plastic covers which will be your quick connect connections the smaller diameter one will be your low pressure side. Be sure to wear gloves and eye protection!!! check to ensure your connection is not leaking and check guage to see if any coolant is left over in the system.If it is completely discharged then ther is a substantial leak which could have caused your system to be contaminated with dirt/moisture loss of circulating oil in which you would just be throwing your money away recharging the system without finding the leak/s and repairing them. If coolant is still present, then check first for obvious leaks by checking for refrigerant oil on any hose, tubing, and fittings that are a part of the refrigerant system, next you could take some soapy water pour it on and look for any bubbles to appear which indicate a leak otherwise you would need a gas or coolant leak detector or a can of leak detector run through the system with a colored dye or one detected by a uv light. A small leak could allow your system to function for months before it fully depletes. Also if your compressor cycles on and off every couple of seconds that is from low pressure. Otherwise tap your can of r134a make sure the can remains upright at all times open valve to allow flow to low pres line your vehicle will need to be running with the ac on high cool DO NOT OVERFILL!!! keep your eye on guage I always put a thermometer in one of the vents you should have cold air between 38-45 degrees otherwise you may need several cans to completely fill system or one of the components I discussed earlier will need to be repaired for more efficient cooling. Let me know if you have any other questions and how this works out for you.

97 Olds Aurora AC blowing warm air a day after recharging system

Several- The system should hold freon for years without leaking. There are pressure switches and they cut off the compressor with an undercharge and an overcharge. You need guages to measure the charge. There are testers the A/C shops have called "sniffers" which can detect a leak. If you have no leak then you need a technician to add or remove freon to get the concentration right. Or you need guages.
