You cannot get R12 anymore. You have to get it converted to a 134a system. Auto parts stores have them. There is a label under the hood that has the charge information on it, but may be inaccurate with 134a. You charge by pressure. You have to evacuate the system for a couple hours before you add the new freon assuming the system has no leaks.
You will need to replace the control board. The board controls the controls the compressor and it is not allowing it to kick back on after the unit has cooled. Here is the board to order.
The part comes with a 365 day, any part, any reason return policy.
Try to check if you have enough freon. You may also try to clean the evaporator of your AC. Dirt might be clogging to the evap that is whay you are not getting the temp that you want.
if u adding through a can from a parts store, u need to have the system evacuated 1st to make sure u dont have any in there before u add the incorrect amount and lock up the system.
Hi
The R134 capicity for your truck is 64oz with rear a/c.
If the system hoses have been disconnected or if you
are replacing any of the system components ie.
compresor/condenser or reciever drier. It is importent
to evacuate the system to remove any moisture from the system before charging, to avoid problems down
the road, I recommend taking it to somone that has
the proper equipment to ensure all moisture is removed and it gets the proper oil charge and won't
get air bound, plus any leaks that remain will be detected. A proper evacuation and charge can be the
difference between luke warm and COLD air.
Hope this helps.
any charge port will evac the system
the compressor will not be running
adding oil is not necessary as there is enough in the replacement compressor
run the vacuum pump for a couple of hours and then lock of the system to see it it holds vacuum
first "Evacuate the system" make sure it holds 18" of vacuum. If it does it is safe to charge you must put the oil back in the system after evacuation and before the refrigerant. The amount of refrigerant should be marked on a label under the hood.
Hi. To answer your question, yes and no. If it has R-12 in it, it needs to be removed, or, as we call it, evacuated. Then, you buy a new kit that has everything you need to adapt the R-12 fittings to the new style R-134A fittings. Then, after the system is empty, add th 134A. We do not recommend that you put R-134A into a system that already has R-12 in it. You could damage the compressor.
need to evacuate the system check the orifice tube put back together and re-vacuum system to remove the air from the system. it's cycling to fast which means air in the system.
any air left in the system will counter any refrigerant in the system.
Since '92 Hondas come with R-12 there will be R-134a adapters on the high & Lo pressure fittings that go over the original Schrader valves hose fittings. These attach to the top of the original R-12 fittings so you should be able to see them installed over the originals. R-134 hoses won't fit R-12 fittings- this is the primary way that prevents folks from putting in the wrong types of freon.
Conversion kits come with stickers to put on the car indicating that it has been changed to R-134a so you can look for that IF whomever did the conversion followed through with putting them on. The best way to know for sure is to compare your fittings with R-12 & R-134a fittings to see which ones you have.
Evacuating the R-12 is easy, but it is a state jail felony in most jurisdictions unless you have a recycling system and a license to handle it.. R-12 is an expensive commodity and you should have no problem finding a facility that will evacuate your R-12 for free. No more R-12 is being made, it is hard to find & very expensive and will only get more so.
I would find an independent auto A/C guy or gal to do business with who will recycle the R-12 then flush, vaccuum & refill with 134a for free or minimal costs after you do the seals and kit, because R-12 is very hard to find, very expensive with lots of paperwork and must be bought in large amounts that are cost prohibitive even for an A/c shop. If someone wants to charge you for taking your R-12 just move on down the road to the next guy because they will likely rip you off on other things too. Find someone you can work with and have a rapport- the good ones will talk you through what you need to do to convert & will be happy to get your R-12 in return for those services. If you are in a large city there are probably several wholesalers who sell everything you need and will do the evacuation and refill for you for trade- provided you have enough R-12 remaining that is worth their efforts..
