My '04 Tahoe's heater core took out the entire dashboard last February
I spent three days pulling apart my dash to replace a $45 part that GM designed to fail right behind the radio. The plastic housing cracked at 78k miles and dumped coolant all over the passenger floor. Dealer quoted me $1,200. Did it myself with YouTube and a socket set, but whoever thought routing that hose through the center console needs their head examined. Anyone else run into this on their GMT800?

Oh come on, that hose routing makes total sense! They wanted to keep the core close to the passenger side for heat distribution. Plus the center console is the safest spot from crash damage. I actually swapped mine out at 95k and the plastic was still fine. Might be a batch issue but not a design flaw. YouTube videos just make it look harder than it is.
