Had fluid leaking into passenger floorboard several months ago, only when defroster was running, & only occasionally. (Assumed heater core was going out?) Last week, upon turning on heater, there was a constant noise from behind the glovebox, that sounded like a leaf or something stuck in the fan, & within 15 minutes, the heater started blowing cold. Have read that it is common problem on these trucks with the blend door breaking (fixed w/heatertreater). Temp gauge working normally, A/C ok, nothing leaking in floorboard at present, just no heat & the clicking noise when fan is on. Is this the blend door prob, or the actual heater core itself, or something else?
have the same problem?
