When the problem presents I turn off the A/C for a couple of minutes and then it starts to work fine again, also if I set the blower to the max. sometimes it helps.
It always feels like the engine of the car is really suffering when the A/C is on, it does not overheats or anything but it just feels like is "overworking" more than what the normal would be. Also it makes way more noise, I know this because this is the second Montero Sport I have and I know how is supposed to sound and feel when the A/C is running.
Another thing is that if the temperature outside is 80 or over it does not cools off if the car is park or going at a very low speed.

    your compressor could be starting to sease up, when a compressor locks up, it will put a heavy drain on your motor,, when you notice this drain, cycle your AC system OFF, if your motor seems to be better I would have your compressor checked by a qualified AC tech.. when was the last time your AC freon level was checked? also if you have had freon put in recently, did you have compressor oil put in as well? could be low on oil too..
