I was driving down the freeway today turned my ac on, it blew cold air for about 25 seconds then started to flash on and off blowing cold air. I have never ran into this before but it seems as though the computer is trying to tell me something. Hopefully someone will know, otherwise I will take it in. Thanx for any input.

 

it's your A/C compressor. it is a frequent problem with a lot of SC's. if you would do a search you will find lot's of good info.

 

Sorry to tell you but it means there has been a catastrophic A/C system failure, usually the compressor has died.
