My 2004 Montero gen 3 limited is losing its heat. I first noticed it a few weeks back when the heat on the pass side felt less hot. Now only the far left vent is getting any heat. Radiator was just flushed this summer and is still full and looks good. When I dial the control from cold to hot I can hear a motorized sound under the dash kind of behind the steering wheel but can’t specifically hear the door shutting. The left vent changes temp from cold to hot but the others stay cold. Could the blend door be only partially functional? Or is it more likely a clogged heater core? Anyone know how to get to the blend door to check it out?
Also when I have the fan on full and switch from cold to hot there is much less air coming out on hot vrs cold. The cold setting seems much more powerful. Not sure if a malfunctioning blend door would cause that.
Thanks for any insight! Hoping I don’t have to remove the whole dash.
