I'm having a problem with my 1996 LT1. When I try to use the a/c, or heat, or defroster, anything using the climate controls, it will work for about 5 minutes, and then stop blowing air. Everything seems to work well when it's working (a/c is cold, defroster works well, ect), but only for a few minutes, and then stops blowing. It sometimes starts working again about 30 minutes later, but I'd like to get this fixed so I have air conditioning, and especially defroster in the winter. Any suggestions would be greatly appreciated!

 

Only when the fan is on high speed and or slower speeds?
