Does your a/c blow hot air when your Yota is not moving? Have you found a way to fix this problem?

Didn't you answer your own question with that link???

Mine takes a few miles to stay cold at traffic lights in the hot afternoon when I first crank it up, but after it finally cools the truck off it will keep the truck cool inside in 99 degree weather at idle indefinitely on recirc...

I would also check that the fan is operating properly....

Dose anybody know the size of that fan in front of the condensor?

Mine did the same and keeping in mind that it should be spinning with AC on at idle this is what I found on my 90 3slo:
As you are looking at front of vehicle, just left behind grille is the AC fan. Just right of grille center is a resistor block with two wires. One wire was broke at resistor or the spade the wire hooked to was broke off at resistor, replaced resistor with bone yard donor and then it worked great from then on spinning like mad with AC on at idle. I assume it cuts off after some road speed, but I couldn't run fast enough to confirm.
Hope yours is the same and this helps.

I had a similar problem and cleaned the fins on my radiators and viola, cool air at idle, Very cold air while moving. Better all the way around.
