I have searched for a possible answer to my issue and may have gotten close, but thought I would ask flat out. Sorry if this is a re-post.

My A/C starts out blowing cold air and after about 10-15 minutes I can still hear the (blower) fan working, but nothing is coming out of vents. If I hit the A/C button to off, it starts blowing very cold air in about 30 seconds, and continues to do so for several minutes. After the air starts to warm up, I turn the A/C button back to On and it works again for another 10-15mins and process starts all over again.

It almost seems like it is building ice up in the system and blocking the air, then after turning the air off, the vent air is just passing over the ice build-up, thus continuing to blow cold air. This is compounded on days when the outside temp is very hot. Also have experience condensated air blowing from the center vents.

Any thoughts??
