Car Forum / Oldsmobile Cars / February 2006Bravada Heater Failed
My 2000 Bravada heater is running all cold lately. The heat went out gradually. I had dexcool init when I bought it, but shortly thereafter found out it had been run too hot and solidified. I have had the system flushed, multiple times, twice in the year before the heat went out, 4 times since. The thermostat has been replaced. The fluid the comes out during the flush is very hot. I've been told the heater coil and radiator are ok. Any other ideas what the problem is? Are both hoses to the heater hot? If so then my guess is that the temperature control door (this is on the air flow side) is not working. > My 2000 Bravada heater is running all cold lately. The heat went out > gradually.

Any other ideas what the problem is? The top hose gets HOT, but the bottom hose gets only warm at best. Someone at work said maybe the core needs to be blown out. Does that make sense? Yes, your findings suggest that the core has low flow through it. A reverse flush might help out. > The top hose gets HOT, but the bottom hose gets only warm at best.
