Yet another AC question

[ND 4 SPD SHO]

Just got my AC recharged(r-12 still). It'll work for about 10 min, then
it'll start blowing warm and extremely humid air. Let the car sit for a
little while and it'll do the same thing. Do I have a drain clogged up
somewhere or what? Any ideas appreciated...

Sounds like you've got a worn clutch. When the coil on the pulley is cold it can flow more current therefore producing a more powerful magnetic field. This enables it to overcome the air gap between the clutch and pulley. This problem has been addressed in many previous posts. Go to the shotimes.com website and there is a thorough write up on how to fix the problem.

Make sure at least one of your fans is running..I had that problem and it was the inboard fan...It would blow cold untill the car warmed up...

Zolton,
There is not enough information to give you a guess as to what the problem might be. You had the system recharged, did you have the leak fixed?
If the system had to be recharged, it has a leak!
Are your fans working properly? Is the compressor clutch cycling? Do the fans come on when the A/C is turned on? When you had the system recharged, did the mechanic check the high and low side pressures? If your system is blowing warm air, there is a problem with heat transfer, assuming your fresh charge has not leaked down. The next question is what part of the system is not working properly? Is it the compressor clutch and/or clutch coil, or possibly the orifice tube has become restricted? If you paid to have the system recharged you should go back to the mechanic who did the work. rangerj
