Just a quick follow up on this issue. One small note, this is my wife's truck so I don't drive it much.
When the "pump noise" goes on it goes away once you give it gas. The only thing I can thing of is, the issue is the ASS coolant recircling cycling pump not operating correctly.
I think she...
I need a bit of help. We have a sound that comes on briefly and it sounds like a pump. The dealer wants the truck for three days and they don't have a loaner program.
It runs year-round and I switch off the ASS system every time I drive. The sound does stop when I turn off the fan.
Any thoughts...
We have a droning fan sound that comes and goes. It turns off when we turn off the hvac fan. The dealer said they would need the truck for three days to check it out. Any thoughts?
