My dodge dakota blows air fine but it is like room temperature air even when on the warmest setting. Winter is fast approaching and I'm trying to figure out what it is. I have a slow anti-freeze leak so I topped of the levels to see if that was the problem..but its not. Any ideas or any help??? Thermostat? Heater Core?
Thanks in Advance
if it doesn't, then you might need to check to see if the valves are fully opening to allow heat to flow into the cab. also, if neither one of those fix the problem, you might have a bad heater core. are you getting fluid in the cab?
