2001 U320 42' with two slides.
I have a problem with living room slide bag inflating after extending. I turn the key on and wait for amber light and bag to deflate. I push extend button with red light on until you can hear pump quit and red light goes out. I turn off ignition key and key at the extension control. Bag around it does not inflate...suggestions??? I tried search but must be entering wrong verbage...I know I'm not the first..

Mike, is the aux compressor running? It usually will be. There is an aluminum box on the ceiling of the bay where the compressor is located, on the drivers side, that has indicator lights. See if any faults are indicated. If one of your locking pins didn't engage then the air bladder may not inflate. Here are the HWH manuals if you don't have them.
