Toyota often replaces the evaporator with this condition but even if they do the condition will most likely return.
 
First, DO NOT allow the A/C compressor to run unless actual cooling, initial cool down, is REQUIRED. A/C dehumidification of the cabin airflow results in the evaporator, think SPONGE, being left saturated with moisture once the A/C is switched off.
 
Dark, moist, dank A/C plenum, perfect breeding area for the microbes whose "leavings" produce that rather horrid mould and mildew odor.
 
In the mean time it helps, really helps, if you can leave the windows lowered, even slightly during times the car is parked under shelter. That allows the accumulated moisture to evaporate and be flushed out of the cabin.
 
Many upscale vehicles now have a UV light mounted within the A/C plenum to combat the microbe breeding. Toyota has experimented over the years, since '91, with several anti-microbe, fungicide, coating on the ~10,000 sq. inches of evaporator surface area. These have either been found to be detrimental to human health or wash away too quickly.

My 2005 Camry is blowing hot air with the indicator light flashing. I have checked other online forum early this summer (May) and following the suggestion, I replaced the clutch relay (placed in the fuse box under the hood) and after done that the AC went to back normal. Then just last week, the AC broke again. I unplugged the clutch relay and put it back on, then the AC started working just fine. However, yesterday, the AC stopped working again. Does anybody have any idea what's wrong with my AC? By the way, it also seems like the AC is more likely to broke when outside temperature is hot.

#100 of 107 compressor failure? 98 LE by eliotb

Sep 10, 2011 (7:29 am)

Hi: the car is a '98 camry le, 4cyl with 95k on it. a couple of months ago the AC began to get weak and i was hearing a noise that rose with engine speed, then fell as the tranny shifted. It goes on when the AC clutch engages. Goes off when the clutch disengages. As mentioned, AC output is weak now.
 
Local shop says compressor, probaby the bearings, is going bad and quotes me roughly $900 to replace compressor and drier, and maybe an expansion valve.
 
Questions: does this diagnosis sound correct and does the rough estimate seem appropriate? Since we are going into fall and I've dropped about $2,350 into this car in the past year I thought I'd wait to spring. (previous work was oil pump seals, water pump, timing belt, starter, battery and new tires)
 
Thanks.

Your engine is "threatening" to overheat and the A/C is disabled automatically.

I had the same problem with my 99 solara, read about blending doors,and switches, and vacuum lines and after I spent many hours and scraped knuckles found nothing! As a shot in the dark I tried one of those cheat Walmart/autozone 134 recharge cans..... Worked great for the rest of the season, come to find out it was just low... It's starting to get warm again and same thing, thinking I had it all figured out, tried this agian... All I found was two empty cans and no ac.... After looking further I found the actual problem. The thinner line (liquid line) coming from the firewall to the dryer has come loose from the clips and was rubbing on e belt creating the leak. $85 from the dealer waiting on it now. This is why I'm back on the Internet ... Looking for an easier way to replace this line... Lots of bending and spinning to get the old one out. Worried about damaging the new one when I put it in. Also question if I should replace the dryer since I'm there anyway???

Air stops blowing altogether, or stops providing cooling..??
 
For the former your evaporator is likely freezing over/up.

Engine tending toward overheating maybe.
 
In that case A/C will be disabled if the engine coolant temperature gets too close to overheating, not actual overheating, just close.
 
Check for failure of the radiator cooling fan(s) and in various operating modes, high speed, low speed, etc.
