Last winter I wrote about this and it happened again this winter. So the booster, which is under the cab, came out. Turns out it was full of moisture and the source of the moisture was the breather filter which is mounted in the rear corner of the cab behind the seat on the driver's side. The filter can was completely rusted out and the breather hose had ice in it. Apparently water was able to drip onto the filter through a seam in the cab above the filler cap. If you have one of these trucks, you might want to check that area out before you have the same problem. JH
