Old thread but anyways sounds like it's working normal. I had one of these Webasto Blue Cool units when they first came out several years ago in a company truck. Piece of crap. You can stay marginally comfortable for about 4 hours (give or take) in the summer time with the unit. There are a few things you must do in order for it to work better. The system re-charges as you are driving down the highway and takes a good 10 hours driving to fully charge up so you'll allegedly have 10 hours of comfort time sleeping. While you're driving that 10 hours you must keep the sleeper curtains closed and seal off the bunk from the cab. You also should turn the bunk AC fan on high andf set the temp as cold as possible. It'll be like an icebox when you climb in the bunk and go to bed - make sure to close the bunk curtain behind you. What the unit does is recirculate that cool air. If it supposed to create it's own cool air it always did a poor job imo. I always ended up idling the truck to stay comfortable. If you have a top bunk you might even try closing it off by letting that down and hanging a sheet over the side to where your bunk area is "sealed off" and the unit is only recirc'ing air for that small area you sleep in. Yeah if you don't these things the unit is pretty worthless and ike I said only works marginally well for a few hours even doing that. If you're in 90-100* weather you can pretty much figure that half your 10 hour break or more is going to be idle time to stay comfy.
