Sorry for the late response, been real busy recently so haven't gotten much work done on the 80. Ended up replacing expansion valve and recharging. After driving around and then hooking up gauges, low side read 30 and high side 210 at idle with ambient temp at condenser of around 85 degrees...
I replaced all the items because the clutch was for sure broken on the compressor so I assumed complete failure. Prior to installing all new parts, I did flush out all the lines and the evaporator. I did make a mistake in the process of flushing. I installed the new TXV and then flushed...
What would be examples of restrictions? Fan clutch is brand new. Condenser and radiator are brand new. Heater valve is fully shut. I'm thinking possibly evaporator not doing it's job?
lol I live in Florida so that could be a possibility but the fact it's not blowing very cold leads me to believe something i malfunctioning. My 92' 80 Series blows ice cold and will cycle on the hottest of days in Florida.

Recently replaced most of the A/C system. Installed new compressor, condenser, dryer, expansion valve, pressure switch. Using vacuum pump, removed moisture and added freon with manifold gauges. Low side pressure was around 25 and high side pressure 275ish (maybe a little higher) with...
My LX470 has the VGRS, VSC OFF, and VSC TRAC lights on. They are steady and remain on all the time while driving. Took it to Toyota to get diagnosed and the codes pulled were ABS: C1289, C1291, C1340 VGRS: C1554, C1568 AHC: 1777. I was told these are all related to the VGRS going bad except for...

I have a 92' 3FE LC. Recently I replaced my fuel sender with another used unit that was known to be in good working order because my gauge needle was jumping/dancing and not marking correctly. The needle shows a fairly accurate depiction when I accelerate and then I let go of gas pedal, the...
So that indeed was the issue. To solve my problem I had to use the r12 fitting to fill the freon from the low side. Found an old r12 gauge set I had lying around and bought some brass pipe fitting to adapt the r12 low side hose to the r134 gauge. I then proceeded to fill 2 12 ounce cans (first...
So I think I found the issue. The r134 adapter to the service port is not pushing in the original r12 Schrader valve in deep enough. To test this, I took the top cover off the compressor which houses both the high side and low side service ports. I then attached the gauge hoses to the service...
Ok, so I did as you instructed. Filled high side with one entire can with vehicle off (liquid fill) and attempted to fill low side (with vehicle on), but compressor would not take the r134. I shook the can (not upside down) for about 50 minutes before I stopped because I felt I was making no...
Ok, I have done this to a tee EXCEPT I open the low side fully when I do it, thus getting those high pressure numbers (80-120) on the low side you mentioned. I will reattempt all steps again as you've described and get back with the readings.
Correct, the evaporator was not replaced. Also, correct in that I flushed the remaining lines and evaporator. I did so by using one of the pressurized ac flush kits with Johnsen's Flush solvent and just blowing the solvent through the lines/evaporator.
I added a total of a little over 7 ounces...
Brian,
Did as you instructed and the system took the whole can on the high side in a few minutes. Turned the land cruiser on and started trying to fill the low side. Pressure was around 130 and wasn't taking freon. Clutch was engaged as soon as I turned the A/C on. I then stopped trying to add...
