Blew heater hose help

[Cwmartinjr]

I blew my heater hose that goes under my driver side to the sleeper on my 2014 cascadia and lost my speedometer, cruise (which I belive to be linked to my speedometer) and what weird is my dash selection for my a/c controls. I have a feeling that something got wet but not sure where.

How or why did that heater hose blow on you? Was it rubbing against something, old hose, a lose clamp, plugged heater core or was it internal pressure that physically blew a hole in the line? Just curious.

Just a old hose. When I replaced my hoses I didn't know those where there.
