Climate control module has been replaced twice. Works correctly for several days and then blows heat only

Do you hear the compressor cycling on/ off regularly? Every couple of minutes. If not and it is cycling on/off every few seconds,I would suspect the system is low on freon. If it was serviced recently then I would suspect a leak in the system that relates to the lack of freon.
If just low on freon, shops have cans with gauges that can be purchased to top off the amount of freon in the system. Otherwise you'll need to find the leak.

I have a 2008 Honda Civic which blows cold hair at first and then starts blowing warm air.

It sounds like you are just tossing parts on it, not diagnosing it first. Sometimes it is cheaper to pay a professional. Does the compressor stay running when it isn't cold? If so, is the return pipe, (the large 1) cold? When you replaced the freon, was it evacuated proprely, with a vacuum pump, for at least 20 minutes at -28 psi vacuum? If the compressor turns off when it gets warm, is power still going to the compressor? If it is, the magnetic coil is failing and/or the clutch gap has become excessive, not unusual on higher mileage Hondas. Your question about the fuse baffles me, why even ask, just replace it with a spare fuse.

How do I find and repair a/c freon leak?

There is a kit for finding the leak. First degrease any parts related to the AC system (hoses and lines especially). Most auto parts stores sell a kit that has a UV (ultraviolet) dye in it for this purpose. You charge the system with it and after a few days of running it you can shine a UV light on it and the area where the leak is will glow and show you the general area of the leak.

2006 Ford Fusion Air Conditioning compressure not turning on.

Thats pretty high if the system is not running. Average pressure on the low and high side should be near outside air temp.
Normal low side is 30-40 psi and high side is 200-250 psi when the system is running and the freon charge is full.

Air Conditioner does not stay cold in my 1991 Honda Civic, freon does not hold, what is it going to cost me to get it working again?

Hi, it sounds like you have you have a leak. Bringing your car in for service for this kind of repair usually can cost several hundred dollars, 300 - 500 $. This problem is usually a leaky o-ring at one of the hose connections, so in order to find it you need to put a dye tracer in with the freon. There is possible ways that you could fix it your self. First go to your local auto parts store and pick up a can of freon with a sealer in it and give that a try, or you can go all out and get a kit that has what you will need to trace the leak, then you can replace the defective part and then re-charge the system.

Your Honda takes R12 freon, R12 freon is no longer sold, if your car has not been retro fitted to 134a freon, you will have to buy a retro fit kit, so you can install 134a freon, If it has been or after retro fitted, total freon 1.5 lbs 134a freon.

My 99 s10 blazer has ac problems. i tried to fill the refrigerant and the psi bounces between 55 and 20, it starts at 20 the builds to 55, then the clutch kicks on and the psi drops back dowm to 20. this...

I'm assuming that's the high side pressure reading. It sounds like you don't have enough refrigerant in there still. Depending on outside temperature the high should be around 130-150 and the low side between 25 - 30 or so with the compressor clutch engaged. Once you connect the can to the low side you'll have to start the car and turn the a/c on to get more in there until the pressure readings are correct.

Air condition is not cooling my honday civic lx 96? I bougth a freon's cane and hook it up but the freon doesn't get transfer into the car?what I am missing?

you need to put a pressure gauge on the freon input nozzle and see how much freon is already in your system You are probably getting no cooling because the clutch on the front of the A/C compressor is broken, or the switch on the dash is not opening the vents inside correctly. Putting more freon into an already full system can have unpleasant results. So if when checking the gauge, the freon levels are ok, next, run the car, and look at the front of the A/C compressor.see if the clutch clicks in and out as the A/C is turned on/off. If the clutch free-spins all the time it needs to be replaced, or if its silent completely, the wiring to the A/C needs to be checked. If the clutch is ok, head under the dash ad listen for the vent doors opening and closing as you cycle the A/C on/off. If you can't hear them, a vacuum pipe or electrical connection/A/C switch is to blame.
