Hoping we can find a solution to our AC problem. Normally our AC is just blowing out warm air when AC is on. Warm air comes out in front and back of van. The air does not normally work but once in awhile you can actually hear a transition happen and the air will start coming out cold. The warm air pressure will slow and you can tell the air is switching back on. We just had the freon tested and we have no leaks. When we first started noticing a problem with the air it would only work if we were driving fast like on the freeway. Once we slowed or if we were driving down a road where we had several stops it would switch and start blowing warm air again.
Hope this makes sense to someone! Thanks!
