@Dave 2000 talks about this in his thread. He wired up an electric fan in lieu of the mechanical fan and reports some interesting results. Didn't @jcardona1 use an electric fan to help with his AC?
Air conditioning compressor, rocket science? (1 Viewer)

I copied jcardona1 electric fan set up and works great! I'm in the same boat
and having AC issues....about to replace compressor, drier, low line and expansion valve...can't wait to get my AC fix
All good suggestions--another issue that has come up is the heater valve not closing all the way and letting some warm water in--the AC overcomes this when operating efficiently(at speed), but can't overcome it at idle....
Good luck

When they do the "busy and not the kinda work I wanna do thing", I tell them, "Sorry I don't want to bother you, I had no idea you were so busy, and leave. They get the point right quick. You are the customer and they are earning your $$$$. Also if they wont' answer your questions go elsewhere....It's part of sales.

I replaced:
Compressor
Fan clutch
Water pump
Filter.
Its working but its not cold at idle. I still need to drive down the road and after a while its ice cold.
I purchased a $99 vacuum and then those stupid cans.
I noticed one is "Artic Freeze" with oil sealant. A local shop refused to vacuum it out fear of damage.
Can it be vacuumed and charged by a shop?
About 8 years ago it was not cold and we just had it topped off by a store and it was awesome so I assumed this is the case again?
Things to try, new fan belts.

Jay, don't take this the wrong way, but its clear....you don't know what you are doing with respect to A/C work.
At this point, you've just been 'throwing parts at it' and not achieving your goal (cool air at idle/low speed).
While there have been many well meaning suggestions given here, I recommend you take your rig to a professional, tell them what you've done already and let them sort it out. OR...study the situation more thoroughly, buy/rent the proper tools and have a knowledgeable mentor come help you.
Hope you get it worked out. Its getting pretty hot out there.

um, not so much... I have taken out many, many burnt up cooling parts and have also done the 120K service of belts and water pump and air conditioning clutch. Next is to remove the heater coil and see if there is a dead beaver or dead opossum stuck up inside.
Today we found the belt was new but sloppy and we are doing that tonight.
Am I stupid? Sure! No one can take that title from me, But I have so much metal that I need to cut corners and do this week end warrior.
Plus can you recommend a good toyoya guy in 96001? no so easy unless you like Lithia Toyota and I dont.
When I asked for a used 2008 "FJ200 Land cruiser" they had me drive 2 down to look at a stupid "FJ" I told them its sacrilege words and drove away.
What im doing is a major refreshing of my FJ80 that I have had for over 20 years.
sorry to many Cruisers and to many beers to do spell check

yes to mere mortals. I forget I just walk among them.

Hi Jay,
As mentioned previously....I mean you no 'offense', in fact applaud you for doing the work yourself and trying to maintain your cruiser. I am only concerned that you might not fully understand the workings of an A/C system and what is required to achieve your goal.
You did not go into any detail as to 'how' you replaced the compressor, pumped the system down and then recharged it. I didn't see any mention of the use of 'gauges' to help diagnose any problems prior to..... or after the recharge.
Any number of things could be causing your problem. If your compressor was shot, then a new one was certainly in order, but did you flush the lines or make any attempt to remove the residual oil in the system? Do you know the condition/function of the TXV on your evaporator (located behind the glove compartment)? IF that is part of your problem you will be evacuating the system all over again to replace it.
Too much (or too little) refrigerant charge can also give you trouble, as will too much oil. The charge should be 'weighed' in...but the use of gauges is also important to monitor exactly what is happening. When you filled the system with refrigerant, did you 'purge' the line first? If not... you just put air and moisture back into the system you just vacuumed out.
Now... all of those things affect the performance of your A/C system across the board and your issue seems to be related to low speed/idle cooling. But since that is when you need cooling the most...it is important that your A/C system be working to full capacity.
My guess is that you do not have enough air flowing across your condenser at low/idle speed for your system to adequately make the heat transfer.
So the first thing to look at is your fan clutch. You said you replaced it? OK, with what clutch? If not the most aggressive OEM for your vehicle then you might not be getting enough air flow even though the unit is 'new'. Do you know your idle speed coolant temps? If your cooling system is not performing correctly then your A/C temps will suffer along with it.
Your A/C belt needs to be tensioned properly of course (easy to do) and check the air gap of the compressor clutch (even if new). If you live in a very hot climate (like many of us), you might consider an AUX Fan (pusher) for added low speed performance, BUT only after making sure your system is working to full potential (both your A/C system and your cooling system).
If you decide to take your vehicle to a 'pro', it doesn't need to be a 'Toyota' dealership or necessarily anyone familiar with them. You only need a person who understands the principles of A/C systems...as it will apply to all vehicles.

Thanks, it looks like the belt tensioner was sloppy. It really jumped to life after a small tweak.
Id love a good mechanic in the area. The last one burt up my FJ40 so im in between mechanics and for the most part will be doing everything my self with my friend and a 6 pack of beer. Ok I have a keg actually.

I have seen several rigs running Freeze 12/Artic Freeze . When setup right it works really well. It is a Propane based mixture. It is OK to replace either R12 or R134a. It is NOT DESIGNED TO BE MIXED WITH EITHER ONE! It will not perform well that way.

I did put the freez and two small cans of the white cans from napa so yes mixed.

I am by no means an expert in automotive AC, but it is not recommended to combine any of the different gases. Most shops will NOt work on propane based gases as it contaminates the R12/R134a. It may be best to evacuate the mix you now have Zander replace with 100% propane based product. It takes much less than either kind of freon, and it runs at a much lower head pressure. That means it is less work for your a/c belt to turn the compressor, and the compressor will generate less heat. I don't remember what/how much oil it requires, but I don't think it is rare or expensive. John
