2002 LSE Air Conditioner Problems

My air conditioner will blow hot air all of sudden for about 2-5 minutes and then it changes back to blowing cold air or sometimes it will only blow cold air if the temperature on set on 65 or 60 degrees. Does anyone else have this problem. I took my car to the dealership and they couldn't find anything wrong(imagine that).

I have a similar problem, but my A/C goes to hot and I have to wait for it to return to cool, which takes 45 - 60 minutes. Do you have a fix to your problem?

The problem is a DCCV Part #xw4z-18495-aa. This controls the flow of hot water through the heater core
