I went for a drive today on the freeway, 70 mph. I decided to try the rear air again and it fired right up, nice and cold. So i hit the front air and it came on just not very hard. The temperature was cold but not as cold as it should be. When i came to a stop the front air went almost completely off. The rear air stayed cold for a few min then started to warm up. When i took off again it got cold again and the front air turned back on. The fan was on #4. It felt like it was on #1
