of 1998 dodge ram 1500 when I cut the AC on it blows cold for about 20 minutes then it starts to get hot not like the heat on justno cold and kinda smell a moisture smell very light could just be the temp change in the truck. So then I cut it off for about 30 minutes and back on and it blows cold again for about 20 minutes. when i bought it the needle valve in the low side was bad so it had no freon in it but i fixed that and filled it up.
Thank you
