ok so after searching a bit I decided to ask for halp. I have a 99 with climate control and some pretty cold air. the problem is that the air only turns off if either A. it was in the on position PRIOR to starting the motor or B. I rev to 3000 rpm at some point in which case it will start blowing cold air but intermittently will blow warm again until I rev again. after awhile it will stay cold but this is really annoying.

 

Sounds like you are low on freon. Its not wanting to cycle since its low. Maybe im wrong. I suck at hvac.

 

well I thought maybe so but after buying a can with the gauge on it, it seemed to be at normal pressure and I even opened the can up to see if it would take any and it didn't.

 

It could be a few things. Overcharging an HVAC system has some very similar symptoms to a system with low refrigerant. Another thing to consider is a vacuum leak causing the blend door to not stay in position causing a little warm air to blow though. Can you hear anything happening under the dash when the air gets warm?
