Help with Air!

My air conditioner is blowing hot and it is starting to make me mad. I tried to recharge the system but it really didn't work to well. My compressor kickes on and off about every 2 seconds. Unfortunatly to charge the system you need the compressor to be on. What could be the problem?

The compressor is short cycling due to low freon levels.
The first thing to find out is why your AC lost the freon charge. Have your vehicle checked by a qualified mechanic.

It may just be a simple seal, or something else requiring big money.

But to get you cool air once again. You can buy a cheap charging hose and a 1 pound can of freon. Turn your AC to the highest setting. Hook up the can of freon and charge the system. After the can of freon, check to see if the comressor has stopped short cycling. If it has, check the temperature coming from your AC vents. If it is cold enough, don't add any more. If it is still warm, add 1 more can. This is not recommended due to the possiblity of overcharging the system without a proper set of gauges.

This will get you cool air at the very least. I would however ask you to have the AC system check by a qualified mechanic.

Good Luck!

Is there anyway of overriding the compressor to keep it on while i fill it?

Once you start filling it the cycling will stop.

Fill the system with one of these available at interdynamics. They are available at Autozone.

Also fill with the AC on MAX and the fan on high.

You don't want to bypass anything. Just add the freon, you will soon see that the compressor will stop short cycling.

Don't worry about the compressor until after you've added the first can of freon.

Make sure you're adding the correct freon. If your truck has R12, you're out of luck. You'll have to convert your system to R134a. R12 is no longer available for the backyard mechanic. :2cents:

R12 retrofitting kits.

All you have to do is get the R12 evacuated for free from a AC service center. They just love to take your R12 for nothing.

R12 ended with the '95 models.

2000 Blazers are R134a.

r12 ENDED WITH 1994.

Thanks guys! My air is blowing ICE COLD! The compressor was shutting off because it had a low charge. Now it is up and running perfectly, thanks again.

you're good to go bro

Is this what were looking to go with?I have no problem with releasing r12 into enviroment

Yip, and I have a BIG PROBLEM WITH YOU RELEASING R12 INTO THE ENVIRONMENT.

You do know that some government officials do patrol these boards and they will see this and can track you down and have a nice intimate conversation with you and your lawyer as they hand you a large fine.

If anyone witnesses you doing that, you could be fined and put into jail.

*Nods* Used refrigerant should be reclaimed and recycled, no matter the grade. Intentionally releasing refrigerant into the atmosphere is severely frowned upon, even the "reformulated" R-134a which is supposed to be more environmentally friendly. If you have a leak, you have a leak, and that cannot be avoided. However, releasing any kind of refrigerant into open air is a serious federal no-no. If you goofed up a recharge or overcharged your coolant - please see a mechanic. The shop will have a machine that will remove and store the waste refrigerant for reclaimation.

I was not actually gonna release it I have somebody that can take it just thought i throw it out there,

just thought i throw it out there,

Well don't.

I was not actually gonna release it I have somebody that can take it just thought i throw it out there,

Then why did you bring it up.

Grow up.

because if i wanted to i could.I was interested in the product page that you listed and did not find a shop till this morn that would do that for free.

I had it removed today but here is my question.He told me before putting the new r134 adapters to put a screwdriver on the low service port.Now wouldn't all the freon be out by this time or is he just trying to cover his tracks?I had the ac on and its hot so i am assuming its out plus it only took about a minute for him to do it.

Ignore him and follow the directions with the kit.

alrighty will do and will report back on how it goes.

Ok hooked up the gauge the first time after retrofitting the high and low adapters and it read 5.I called a different shop they told me to go ahead because thats allowable in the gauge reading.I inserted about a quarter can of it in and the guage shot in to the red.I stopped called back they told me to bleed the 134 out then put rest of can in.So i had them bleed it out then i went and filled it up up.First can and a half compressor only clicked on and off.Then with the third can the compressor finally came on all the time.Another note was how the gauge went into yellow but when it clicked it went to blue then when it finally came on all the time it stayed steady at the blue on the gauge and the air is cool not ice but cool.It feels like my r12 last summer which is good.Should i check pressure in a day or so to make sure i have no leaks.I looked at the system and no dye came out of it anywhere i could see so i do not have any leaks and the high side port adapter cap is on snug because you can not tighten it beyond or it goes loose.Overall one of the easiest things ever to do to this truck after getting everyone fired up.Sorry about that but its better now and i do not smell oil except at stop lights and stop signs.Which is huge improvement.

You aure you are using refrigerant with oil?

Also, yes, check it again in a bit.

You are refilling it with the AC on max and the fan on full blast right?

Yes it is pre mixed.I am using the RkR7kit.It retrofits it.The high low side port adapters screw over top of the existing ones.Yes i filled it withthe ac on max and fan on full blast.I took it for a ride after i was done.My system did not overheat actually ran cooler and it did not go warm.So i figured it was good.Will check pressure either tommorow or Sunday to make sure it is holding.When you notice the difference is when you step out of the truck.

You only need to use the low pressure side to refill.

i know but you have to convert the high side. It comes with its own special adapter.You put it on then the cap and forget it.
